Check the CC and CFLAGS lines in the makefile
If your C library does not support the times(3) function, change the
#define TIMES to
#undef TIMES in speed.c
If it does, check the HZ value for the times(3) function.
If your system does not define CLK_TCK it will be assumed to
be 100.0.
If possible use gcc v 2.7.?
Turn on the maximum optimising (normally '-O3 -fomit-frame-pointer' for gcc)
In recent times, some system compilers give better performace.
type 'make'
run './destest' to check things are ok.
run './rpw' to check the tty code for reading passwords works.
run './speed' to see how fast those optimisations make the library run :-)
run './des_opts' to determin the best compile time options.
The output from des_opts should be put in the makefile options and des_enc.c
should be rebuilt. For 64 bit computers, do not use the DES_PTR option.
For the DEC Alpha, edit des.h and change DES_LONG to 'unsigned int'
and then you can use the 'DES_PTR' option.
The file options.txt has the options listed for best speed on quite a
few systems. Look and the options (UNROLL, PTR, RISC2 etc) and then
turn on the relevent option in the Makefile
There are some special Makefile targets that make life easier.
make cc - standard cc build
make gcc - standard gcc build
make x86-elf - x86 assember (elf), linux-elf.
make x86-out - x86 assember (a.out), FreeBSD
make x86-solaris- x86 assember
make x86-bsdi - x86 assember (a.out with primative assember).
If at all possible use the assember (for Windows NT/95, use
asm/win32.obj to link with). The x86 assember is very very fast.
A make install will by default install
libdes.a in /usr/local/lib/libdes.a
des in /usr/local/bin/des
des_crypt.man in /usr/local/man/man3/des_crypt.3
des.man in /usr/local/man/man1/des.1
des.h in /usr/include/des.h
des(1) should be compatible with sunOS's but I have been unable to
test it.
These routines should compile on MSDOS, most 32bit and 64bit version
of Unix (BSD and SYSV) and VMS, without modification.
The only problems should be #include files that are in the wrong places.
These routines can be compiled under MSDOS.
I have successfully encrypted files using des(1) under MSDOS and then
decrypted the files on a SparcStation.
I have been able to compile and test the routines with
Microsoft C v 5.1 and Turbo C v 2.0.
The code in this library is in no way optimised for the 16bit
operation of MSDOS.
When building for glibc, ignore all of the above and just unpack into
glibc-1.??/des and then gmake as per normal.
As a final note on performace. Certain CPUs like sparcs and Alpha often give
a %10 speed difference depending on the link order. It is rather anoying
when one program reports 'x' DES encrypts a second and another reports
'x*0.9' the speed.

[ This is an old file, I don't know if it is true anymore
but I will leave the file here - eay 21/11/95 ]
To use this library with Bones (kerberos without DES):
1) Get my modified Bones - eBones. It can be found on
gondwana.ecr.mu.oz.au (128.250.1.63) /pub/athena/eBones-p9.tar.Z
and
nic.funet.fi (128.214.6.100) /pub/unix/security/Kerberos/eBones-p9.tar.Z
2) Unpack this library in src/lib/des, makeing sure it is version
3.00 or greater (libdes.tar.93-10-07.Z). This versions differences
from the version in comp.sources.misc volume 29 patchlevel2.
The primarily difference is that it should compile under kerberos :-).
It can be found at.
ftp.psy.uq.oz.au (130.102.32.1) /pub/DES/libdes.tar.93-10-07.Z
Now do a normal kerberos build and things should work.
One problem I found when I was build on my local sun.

Modes of DES
Quite a bit of the following information has been taken from
AS 2805.5.2
Australian Standard
Electronic funds transfer - Requirements for interfaces,
Part 5.2: Modes of operation for an n-bit block cipher algorithm
Appendix A
There are several different modes in which DES can be used, they are
as follows.
Electronic Codebook Mode (ECB) (des_ecb_encrypt())
- 64 bits are enciphered at a time.
- The order of the blocks can be rearranged without detection.
- The same plaintext block always produces the same ciphertext block
(for the same key) making it vulnerable to a 'dictionary attack'.
- An error will only affect one ciphertext block.
Cipher Block Chaining Mode (CBC) (des_cbc_encrypt())
- a multiple of 64 bits are enciphered at a time.
- The CBC mode produces the same ciphertext whenever the same
plaintext is encrypted using the same key and starting variable.
- The chaining operation makes the ciphertext blocks dependent on the
current and all preceding plaintext blocks and therefore blocks can not
be rearranged.
- The use of different starting variables prevents the same plaintext
enciphering to the same ciphertext.
- An error will affect the current and the following ciphertext blocks.
Cipher Feedback Mode (CFB) (des_cfb_encrypt())
- a number of bits (j) <= 64 are enciphered at a time.
- The CFB mode produces the same ciphertext whenever the same
plaintext is encrypted using the same key and starting variable.
- The chaining operation makes the ciphertext variables dependent on the
current and all preceding variables and therefore j-bit variables are
chained together and con not be rearranged.
- The use of different starting variables prevents the same plaintext
enciphering to the same ciphertext.
- The strength of the CFB mode depends on the size of k (maximal if
j == k). In my implementation this is always the case.
- Selection of a small value for j will require more cycles through
the encipherment algorithm per unit of plaintext and thus cause
greater processing overheads.
- Only multiples of j bits can be enciphered.
- An error will affect the current and the following ciphertext variables.
Output Feedback Mode (OFB) (des_ofb_encrypt())
- a number of bits (j) <= 64 are enciphered at a time.
- The OFB mode produces the same ciphertext whenever the same
plaintext enciphered using the same key and starting variable. More
over, in the OFB mode the same key stream is produced when the same
key and start variable are used. Consequently, for security reasons
a specific start variable should be used only once for a given key.
- The absence of chaining makes the OFB more vulnerable to specific attacks.
- The use of different start variables values prevents the same
plaintext enciphering to the same ciphertext, by producing different
key streams.
- Selection of a small value for j will require more cycles through
the encipherment algorithm per unit of plaintext and thus cause
greater processing overheads.
- Only multiples of j bits can be enciphered.
- OFB mode of operation does not extend ciphertext errors in the
resultant plaintext output. Every bit error in the ciphertext causes
only one bit to be in error in the deciphered plaintext.
- OFB mode is not self-synchronising. If the two operation of
encipherment and decipherment get out of synchronism, the system needs
to be re-initialised.
- Each re-initialisation should use a value of the start variable
different from the start variable values used before with the same
key. The reason for this is that an identical bit stream would be
produced each time from the same parameters. This would be
susceptible to a 'known plaintext' attack.
Triple ECB Mode (des_3ecb_encrypt())
- Encrypt with key1, decrypt with key2 and encrypt with key1 again.
- As for ECB encryption but increases the effective key length to 112 bits.
- If both keys are the same it is equivalent to encrypting once with
just one key.
Triple CBC Mode (des_3cbc_encrypt())
- Encrypt with key1, decrypt with key2 and encrypt with key1 again.
- As for CBC encryption but increases the effective key length to 112 bits.
- If both keys are the same it is equivalent to encrypting once with
just one key.

libdes is now also shipped with SSLeay. Primary ftp site of
ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz
The best way to build this library is to build it as part of SSLeay.
This kit builds a DES encryption library and a DES encryption program.
It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
triple cfb, desx, and MIT's pcbc encryption modes and also has a fast
implementation of crypt(3).
It contains support routines to read keys from a terminal,
generate a random key, generate a key from an arbitrary length string,
read/write encrypted data from/to a file descriptor.
The implementation was written so as to conform with the manual entry
for the des_crypt(3) library routines from MIT's project Athena.
destest should be run after compilation to test the des routines.
rpw should be run after compilation to test the read password routines.
The des program is a replacement for the sun des command. I believe it
conforms to the sun version.
The Imakefile is setup for use in the kerberos distribution.
These routines are best compiled with gcc or any other good
optimising compiler.
Just turn you optimiser up to the highest settings and run destest
after the build to make sure everything works.
I believe these routines are close to the fastest and most portable DES
routines that use small lookup tables (4.5k) that are publicly available.
The fcrypt routine is faster than ufc's fcrypt (when compiling with
gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
(on a sun3/260 168 vs 336). It is a function of CPU on chip cache size.
[ 10-Jan-97 and a function of an incorrect speed testing program in
ufc which gave much better test figures that reality ].
It is worth noting that on sparc and Alpha CPUs, performance of the DES
library can vary by upto %10 due to the positioning of files after application
linkage.

Version 4.01 14/01/97
Even faster inner loop in the DES assember for x86 and a modification
for IP/FP which is faster on x86. Both of these changes are
from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His
changes make the assember run %40 faster on a pentium. This is just
a case of getting the instruction sequence 'just right'.
All credit to 'Svend' :-)
Quite a few special x86 'make' targets.
A libdes-l (lite) distribution.
Version 4.00
After a bit of a pause, I'll up the major version number since this
is mostly a performace release. I've added x86 assember and
added more options for performance. A %28 speedup for gcc
on a pentium and the assember is a %50 speedup.
MIPS CPU's, sparc and Alpha are the main CPU's with speedups.
Run des_opts to work out which options should be used.
DES_RISC1/DES_RISC2 use alternative inner loops which use
more registers but should give speedups on any CPU that does
dual issue (pentium). DES_UNROLL unrolls the inner loop,
which costs in code size.
Version 3.26
I've finally removed one of the shifts in D_ENCRYPT. This
meant I've changed the des_SPtrans table (spr.h), the set_key()
function and some things in des_enc.c. This has definitly
made things faster :-). I've known about this one for some
time but I've been too lazy to follow it up :-).
Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^..
instead of L^=((..)|(..)|(..).. This should save a register at
least.
Assember for x86. The file to replace is des_enc.c, which is replaced
by one of the assember files found in asm. Look at des/asm/readme
for more info.
/* Modification to fcrypt so it can be compiled to support
HPUX 10.x's long password format, define -DLONGCRYPT to use this.
Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */
SIGWINCH case put in des_read_passwd() so the function does not
'exit' if this function is recieved.
Version 3.25 17/07/96
Modified read_pwd.c so that stdin can be read if not a tty.
Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches.
des_init_random_number_generator() shortened due to VMS linker
limits.
Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2
8 byte quantites xored before and after encryption.
des_xcbc_encryption() - the name is funny to preserve the des_
prefix on all functions.
Version 3.24 20/04/96
The DES_PTR macro option checked and used by SSLeay configuration
Version 3.23 11/04/96
Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha,
it gives a %20 speedup :-)
Fixed the problem with des.pl under perl5. The patches were
sent by Ed Kubaitis (ejk@uiuc.edu).
if fcrypt.c, changed values to handle illegal salt values the way
normal crypt() implementations do. Some programs apparently use
them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se>
Version 3.22 29/11/95
Bug in des(1), an error with the uuencoding stuff when the
'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au>
for the patch.
Version 3.21 22/11/95
After some emailing back and forth with
Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things
and in a future version I will probably put in some of the
optimisation he suggested for use with the DES_USE_PTR option.
Extra routines from Mark Murray <mark@grondar.za> for use in
freeBSD. They mostly involve random number generation for use
with kerberos. They involve evil machine specific system calls
etc so I would normally suggest pushing this stuff into the
application and/or using RAND_seed()/RAND_bytes() if you are
using this DES library as part of SSLeay.
Redone the read_pw() function so that it is cleaner and
supports termios, thanks to Sameer Parekh <sameer@c2.org>
for the initial patches for this.
Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been
done just to make things more consistent.
I have also now added triple DES versions of cfb and ofb.
Version 3.20
Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com,
my des_random_seed() function was only copying 4 bytes of the
passed seed into the init structure. It is now fixed to copy 8.
My own suggestion is to used something like MD5 :-)
Version 3.19
While looking at my code one day, I though, why do I keep on
calling des_encrypt(in,out,ks,enc) when every function that
calls it has in and out the same. So I dropped the 'out'
parameter, people should not be using this function.
Version 3.18 30/08/95
Fixed a few bit with the distribution and the filenames.
3.17 had been munged via a move to DOS and back again.
NO CODE CHANGES
Version 3.17 14/07/95
Fixed ede3 cbc which I had broken in 3.16. I have also
removed some unneeded variables in 7-8 of the routines.
Version 3.16 26/06/95
Added des_encrypt2() which does not use IP/FP, used by triple
des routines. Tweaked things a bit elsewhere. %13 speedup on
sparc and %6 on a R4400 for ede3 cbc mode.
Version 3.15 06/06/95
Added des_ncbc_encrypt(), it is des_cbc mode except that it is
'normal' and copies the new iv value back over the top of the
passed parameter.
CHANGED des_ede3_cbc_encrypt() so that it too now overwrites
the iv. THIS WILL BREAK EXISTING CODE, but since this function
only new, I feel I can change it, not so with des_cbc_encrypt :-(.
I need to update the documentation.
Version 3.14 31/05/95
New release upon the world, as part of my SSL implementation.
New copyright and usage stuff. Basically free for all to use
as long as you say it came from me :-)
Version 3.13 31/05/95
A fix in speed.c, if HZ is not defined, I set it to 100.0
which is reasonable for most unixes except SunOS 4.x.
I now have a #ifdef sun but timing for SunOS 4.x looked very
good :-(. At my last job where I used SunOS 4.x, it was
defined to be 60.0 (look at the old INSTALL documentation), at
the last release had it changed to 100.0 since I now work with
Solaris2 and SVR4 boxes.
Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this
one out.
Version 3.12 08/05/95
As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>,
my D_ENCRYPT macro in crypt() had an un-necessary variable.
It has been removed.
Version 3.11 03/05/95
Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys
and one iv. It is a standard and I needed it for my SSL code.
It makes more sense to use this for triple DES than
3cbc_encrypt(). I have also added (or should I say tested :-)
cfb64_encrypt() which is cfb64 but it will encrypt a partial
number of bytes - 3 bytes in 3 bytes out. Again this is for
my SSL library, as a form of encryption to use with SSL
telnet.
Version 3.10 22/03/95
Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls
to cbc3_encrypt, the 2 iv values that were being returned to
be used in the next call were reversed :-(.
Many thanks to Bill Wade <wade@Stoner.COM> for pointing out
this error.
Version 3.09 01/02/95
Fixed des_random_key to far more random, it was rather feeble
with regards to picking the initial seed. The problem was
pointed out by Olaf Kirch <okir@monad.swb.de>.
Version 3.08 14/12/94
Added Makefile.PL so libdes can be built into perl5.
Changed des_locl.h so RAND is always defined.
Version 3.07 05/12/94
Added GNUmake and stuff so the library can be build with
glibc.
Version 3.06 30/08/94
Added rpc_enc.c which contains _des_crypt. This is for use in
secure_rpc v 4.0
Finally fixed the cfb_enc problems.
Fixed a few parameter parsing bugs in des (-3 and -b), thanks
to Rob McMillan <R.McMillan@its.gu.edu.au>
Version 3.05 21/04/94
for unsigned long l; gcc does not produce ((l>>34) == 0)
This causes bugs in cfb_enc.
Thanks to Hadmut Danisch <danisch@ira.uka.de>
Version 3.04 20/04/94
Added a version number to des.c and libdes.a
Version 3.03 12/01/94
Fixed a bug in non zero iv in 3cbc_enc.
Version 3.02 29/10/93
I now work in a place where there are 6+ architectures and 14+
OS versions :-).
Fixed TERMIO definition so the most sys V boxes will work :-)
Release upon comp.sources.misc
Version 3.01 08/10/93
Added des_3cbc_encrypt()
Version 3.00 07/10/93
Fixed up documentation.
quad_cksum definitely compatible with MIT's now.
Version 2.30 24/08/93
Triple DES now defaults to triple cbc but can do triple ecb
with the -b flag.
Fixed some MSDOS uuen/uudecoding problems, thanks to
Added prototypes.
Version 2.22 29/06/93
Fixed a bug in des_is_weak_key() which stopped it working :-(
thanks to engineering@MorningStar.Com.
Version 2.21 03/06/93
des(1) with no arguments gives quite a bit of help.
Added -c (generate ckecksum) flag to des(1).
Added -3 (triple DES) flag to des(1).
Added cfb and ofb routines to the library.
Version 2.20 11/03/93
Added -u (uuencode) flag to des(1).
I have been playing with byte order in quad_cksum to make it
compatible with MIT's version. All I can say is avid this
function if possible since MIT's output is endian dependent.
Version 2.12 14/10/92
Added MSDOS specific macro in ecb_encrypt which gives a %70
speed up when the code is compiled with turbo C.
Version 2.11 12/10/92
Speedup in set_key (recoding of PC-1)
I now do it in 47 simple operations, down from 60.
Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov)
for motivating me to look for a faster system :-)
The speedup is probably less that 1% but it is still 13
instructions less :-).
Version 2.10 06/10/92
The code now works on the 64bit ETA10 and CRAY without modifications or
#defines. I believe the code should work on any machine that
defines long, int or short to be 8 bytes long.
Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu)
for helping me fix the code to run on 64bit machines (he had
access to an ETA10).
Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov>
for testing the routines on a CRAY.
read_password.c has been renamed to read_passwd.c
string_to_key.c has been renamed to string2key.c
Version 2.00 14/09/92
Made mods so that the library should work on 64bit CPU's.
Removed all my uchar and ulong defs. To many different
versions of unix define them in their header files in too many
different combinations :-)
IRIX - Sillicon Graphics mods (mostly in read_password.c).
Thanks to Andrew Daviel (advax@erich.triumf.ca)
Version 1.99 26/08/92
Fixed a bug or 2 in enc_read.c
Fixed a bug in enc_write.c
Fixed a pseudo bug in fcrypt.c (very obscure).
Version 1.98 31/07/92
Support for the ETA10. This is a strange machine that defines
longs and ints as 8 bytes and shorts as 4 bytes.
Since I do evil things with long * that assume that they are 4
bytes. Look in the Makefile for the option to compile for
this machine. quad_cksum appears to have problems but I
will don't have the time to fix it right now, and this is not
a function that uses DES and so will not effect the main uses
of the library.
Version 1.97 20/05/92 eay
Fixed the Imakefile and made some changes to des.h to fix some
problems when building this package with Kerberos v 4.
Version 1.96 18/05/92 eay
Fixed a small bug in string_to_key() where problems could
occur if des_check_key was set to true and the string
generated a weak key.
Patch2 posted to comp.sources.misc
Version 1.95 13/05/92 eay
Added an alternative version of the D_ENCRYPT macro in
ecb_encrypt and fcrypt. Depending on the compiler, one version or the
other will be faster. This was inspired by
Dana How <how@isl.stanford.edu>, and her pointers about doing the
*(ulong *)((uchar *)ptr+(value&0xfc))
vs
ptr[value&0x3f]
to stop the C compiler doing a <<2 to convert the long array index.
Version 1.94 05/05/92 eay
Fixed an incompatibility between my string_to_key and the MIT
version. When the key is longer than 8 chars, I was wrapping
with a different method. To use the old version, define
OLD_STR_TO_KEY in the makefile. Thanks to
viktor@newsu.shearson.com (Viktor Dukhovni).
Version 1.93 28/04/92 eay
Fixed the VMS mods so that echo is now turned off in
read_password. Thanks again to brennan@coco.cchs.su.oz.AU.
MSDOS support added. The routines can be compiled with
Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined.
Patch1 posted to comp.sources.misc
Version 1.92 13/04/92 eay
Changed D_ENCRYPT so that the rotation of R occurs outside of
the loop. This required rotating all the longs in sp.h (now
called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM>
speed.c has been changed so it will work without SIGALRM. If
times(3) is not present it will try to use ftime() instead.
Version 1.91 08/04/92 eay
Added -E/-D options to des(1) so it can use string_to_key.
Added SVR4 mods suggested by witr@rwwa.COM
Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If
anyone knows how to turn of tty echo in VMS please tell me or
implement it yourself :-).
Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS
does not like IN/OUT being used.
Libdes posted to comp.sources.misc
Version 1.9 24/03/92 eay
Now contains a fast small crypt replacement.
Added des(1) command.
Added des_rw_mode so people can use cbc encryption with
enc_read and enc_write.
Version 1.8 15/10/91 eay
Bug in cbc_cksum.
Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this
one out.
Version 1.7 24/09/91 eay
Fixed set_key :-)
set_key is 4 times faster and takes less space.
There are a few minor changes that could be made.
Version 1.6 19/09/1991 eay
Finally go IP and FP finished.
Now I need to fix set_key.
This version is quite a bit faster that 1.51
Version 1.52 15/06/1991 eay
20% speedup in ecb_encrypt by changing the E bit selection
to use 2 32bit words. This also required modification of the
sp table. There is still a way to speedup the IP and IP-1
(hints from outer@sq.com) still working on this one :-(.
Version 1.51 07/06/1991 eay
Faster des_encrypt by loop unrolling
Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu)
Version 1.50 28/05/1991 eay
Optimised the code a bit more for the sparc. I have improved the
speed of the inner des_encrypt by speeding up the initial and
final permutations.
Version 1.40 23/10/1990 eay
Fixed des_random_key, it did not produce a random key :-(
Version 1.30 2/10/1990 eay
Have made des_quad_cksum the same as MIT's, the full package
should be compatible with MIT's
Have tested on a DECstation 3100
Still need to fix des_set_key (make it faster).
Does des_cbc_encrypts at 70.5k/sec on a 3100.
Version 1.20 18/09/1990 eay
Fixed byte order dependencies.
Fixed (I hope) all the word alignment problems.
Speedup in des_ecb_encrypt.
Version 1.10 11/09/1990 eay
Added des_enc_read and des_enc_write.
Still need to fix des_quad_cksum.
Still need to document des_enc_read and des_enc_write.
Version 1.00 27/08/1990 eay

First up, let me say I don't like writing in assembler. It is not portable,
dependant on the particular CPU architecture release and is generally a pig
to debug and get right. Having said that, the x86 architecture is probably
the most important for speed due to number of boxes and since
it appears to be the worst architecture to to get
good C compilers for. So due to this, I have lowered myself to do
assembler for the inner DES routines in libdes :-).
The file to implement in assembler is des_enc.c. Replace the following
4 functions
des_encrypt(DES_LONG data[2],des_key_schedule ks, int encrypt);
des_encrypt2(DES_LONG data[2],des_key_schedule ks, int encrypt);
des_encrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
des_decrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
They encrypt/decrypt the 64 bits held in 'data' using
the 'ks' key schedules. The only difference between the 4 functions is that
des_encrypt2() does not perform IP() or FP() on the data (this is an
optimization for when doing triple DES and des_encrypt3() and des_decrypt3()
perform triple des. The triple DES routines are in here because it does
make a big difference to have them located near the des_encrypt2 function
at link time..
Now as we all know, there are lots of different operating systems running on
x86 boxes, and unfortunately they normally try to make sure their assembler
formating is not the same as the other peoples.
The 4 main formats I know of are
Microsoft Windows 95/Windows NT
Elf Includes Linux and FreeBSD(?).
a.out The older Linux.
Solaris Same as Elf but different comments :-(.
Now I was not overly keen to write 4 different copies of the same code,
so I wrote a few perl routines to output the correct assembler, given
a target assembler type. This code is ugly and is just a hack.
The libraries are x86unix.pl and x86ms.pl.
des586.pl, des686.pl and des-som[23].pl are the programs to actually
generate the assembler.
So to generate elf assembler
perl des-som3.pl elf >dx86-elf.s
For Windows 95/NT
perl des-som2.pl win32 >win32.asm
[ update 4 Jan 1996 ]
I have added another way to do things.
perl des-som3.pl cpp >dx86-cpp.s
generates a file that will be included by dx86unix.cpp when it is compiled.
To build for elf, a.out, solaris, bsdi etc,
cc -E -DELF asm/dx86unix.cpp | as -o asm/dx86-elf.o
cc -E -DSOL asm/dx86unix.cpp | as -o asm/dx86-sol.o
cc -E -DOUT asm/dx86unix.cpp | as -o asm/dx86-out.o
cc -E -DBSDI asm/dx86unix.cpp | as -o asm/dx86bsdi.o
This was done to cut down the number of files in the distribution.
Now the ugly part. I acquired my copy of Intels
"Optimization's For Intel's 32-Bit Processors" and found a few interesting
things. First, the aim of the exersize is to 'extract' one byte at a time
from a word and do an array lookup. This involves getting the byte from
the 4 locations in the word and moving it to a new word and doing the lookup.
The most obvious way to do this is
xor eax, eax # clear word
movb al, cl # get low byte
xor edi DWORD PTR 0x100+des_SP[eax] # xor in word
movb al, ch # get next byte
xor edi DWORD PTR 0x300+des_SP[eax] # xor in word
shr ecx 16
which seems ok. For the pentium, this system appears to be the best.
One has to do instruction interleaving to keep both functional units
operating, but it is basically very efficient.
Now the crunch. When a full register is used after a partial write, eg.
mov al, cl
xor edi, DWORD PTR 0x100+des_SP[eax]
386 - 1 cycle stall
486 - 1 cycle stall
586 - 0 cycle stall
686 - at least 7 cycle stall (page 22 of the above mentioned document).
So the technique that produces the best results on a pentium, according to
the documentation, will produce hideous results on a pentium pro.
To get around this, des686.pl will generate code that is not as fast on
a pentium, should be very good on a pentium pro.
mov eax, ecx # copy word
shr ecx, 8 # line up next byte
and eax, 0fch # mask byte
xor edi DWORD PTR 0x100+des_SP[eax] # xor in array lookup
mov eax, ecx # get word
shr ecx 8 # line up next byte
and eax, 0fch # mask byte
xor edi DWORD PTR 0x300+des_SP[eax] # xor in array lookup
Due to the execution units in the pentium, this actually works quite well.
For a pentium pro it should be very good. This is the type of output
Visual C++ generates.
There is a third option. instead of using
mov al, ch
which is bad on the pentium pro, one may be able to use
movzx eax, ch
which may not incur the partial write penalty. On the pentium,
this instruction takes 4 cycles so is not worth using but on the
pentium pro it appears it may be worth while. I need access to one to
experiment :-).
eric (20 Oct 1996)
22 Nov 1996 - I have asked people to run the 2 different version on pentium
pros and it appears that the intel documentation is wrong. The
mov al,bh is still faster on a pentium pro, so just use the des586.pl
install des686.pl
3 Dec 1996 - I added des_encrypt3/des_decrypt3 because I have moved these
functions into des_enc.c because it does make a massive performance
difference on some boxes to have the functions code located close to
the des_encrypt2() function.
9 Jan 1996 - des-som2.pl is now the correct perl script to use for
pentiums. It contains an inner loop from
Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> which does raw ecb DES calls at
273,000 per second. He had a previous version at 250,000 and the best
I was able to get was 203,000. The content has not changed, this is all
due to instruction sequencing (and actual instructions choice) which is able
to keep both functional units of the pentium going.
We may have lost the ugly register usage restrictions when x86 went 32 bit
but for the pentium it has been replaced by evil instruction ordering tricks.
13 Jan 1996 - des-som3.pl, more optimizations from Svend Olaf.
raw DES at 281,000 per second on a pentium 100.

The DES library.
Please note that this library was originally written to operate with
eBones, a version of Kerberos that had had encryption removed when it left
the USA and then put back in. As such there are some routines that I will
advise not using but they are still in the library for historical reasons.
For all calls that have an 'input' and 'output' variables, they can be the
same.
This library requires the inclusion of 'des.h'.
All of the encryption functions take what is called a des_key_schedule as an
argument. A des_key_schedule is an expanded form of the des key.
A des_key is 8 bytes of odd parity, the type used to hold the key is a
des_cblock. A des_cblock is an array of 8 bytes, often in this library
description I will refer to input bytes when the function specifies
des_cblock's as input or output, this just means that the variable should
be a multiple of 8 bytes.
The define DES_ENCRYPT is passed to specify encryption, DES_DECRYPT to
specify decryption. The functions and global variable are as follows:
int des_check_key;
DES keys are supposed to be odd parity. If this variable is set to
a non-zero value, des_set_key() will check that the key has odd
parity and is not one of the known weak DES keys. By default this
variable is turned off;
void des_set_odd_parity(
des_cblock *key );
This function takes a DES key (8 bytes) and sets the parity to odd.
int des_is_weak_key(
des_cblock *key );
This function returns a non-zero value if the DES key passed is a
weak, DES key. If it is a weak key, don't use it, try a different
one. If you are using 'random' keys, the chances of hitting a weak
key are 1/2^52 so it is probably not worth checking for them.
int des_set_key(
des_cblock *key,
des_key_schedule schedule);
Des_set_key converts an 8 byte DES key into a des_key_schedule.
A des_key_schedule is an expanded form of the key which is used to
perform actual encryption. It can be regenerated from the DES key
so it only needs to be kept when encryption or decryption is about
to occur. Don't save or pass around des_key_schedule's since they
are CPU architecture dependent, DES keys are not. If des_check_key
is non zero, zero is returned if the key has the wrong parity or
the key is a weak key, else 1 is returned.
int des_key_sched(
des_cblock *key,
des_key_schedule schedule);
An alternative name for des_set_key().
int des_rw_mode; /* defaults to DES_PCBC_MODE */
This flag holds either DES_CBC_MODE or DES_PCBC_MODE (default).
This specifies the function to use in the enc_read() and enc_write()
functions.
void des_encrypt(
unsigned long *data,
des_key_schedule ks,
int enc);
This is the DES encryption function that gets called by just about
every other DES routine in the library. You should not use this
function except to implement 'modes' of DES. I say this because the
functions that call this routine do the conversion from 'char *' to
long, and this needs to be done to make sure 'non-aligned' memory
access do not occur. The characters are loaded 'little endian',
have a look at my source code for more details on how I use this
function.
Data is a pointer to 2 unsigned long's and ks is the
des_key_schedule to use. enc, is non zero specifies encryption,
zero if decryption.
void des_encrypt2(
unsigned long *data,
des_key_schedule ks,
int enc);
This functions is the same as des_encrypt() except that the DES
initial permutation (IP) and final permutation (FP) have been left
out. As for des_encrypt(), you should not use this function.
It is used by the routines in my library that implement triple DES.
IP() des_encrypt2() des_encrypt2() des_encrypt2() FP() is the same
as des_encrypt() des_encrypt() des_encrypt() except faster :-).
void des_ecb_encrypt(
des_cblock *input,
des_cblock *output,
des_key_schedule ks,
int enc);
This is the basic Electronic Code Book form of DES, the most basic
form. Input is encrypted into output using the key represented by
ks. If enc is non zero (DES_ENCRYPT), encryption occurs, otherwise
decryption occurs. Input is 8 bytes long and output is 8 bytes.
(the des_cblock structure is 8 chars).
void des_ecb3_encrypt(
des_cblock *input,
des_cblock *output,
des_key_schedule ks1,
des_key_schedule ks2,
des_key_schedule ks3,
int enc);
This is the 3 key EDE mode of ECB DES. What this means is that
the 8 bytes of input is encrypted with ks1, decrypted with ks2 and
then encrypted again with ks3, before being put into output;
C=E(ks3,D(ks2,E(ks1,M))). There is a macro, des_ecb2_encrypt()
that only takes 2 des_key_schedules that implements,
C=E(ks1,D(ks2,E(ks1,M))) in that the final encrypt is done with ks1.
void des_cbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule ks,
des_cblock *ivec,
int enc);
This routine implements DES in Cipher Block Chaining mode.
Input, which should be a multiple of 8 bytes is encrypted
(or decrypted) to output which will also be a multiple of 8 bytes.
The number of bytes is in length (and from what I've said above,
should be a multiple of 8). If length is not a multiple of 8, I'm
not being held responsible :-). ivec is the initialisation vector.
This function does not modify this variable. To correctly implement
cbc mode, you need to do one of 2 things; copy the last 8 bytes of
cipher text for use as the next ivec in your application,
or use des_ncbc_encrypt().
Only this routine has this problem with updating the ivec, all
other routines that are implementing cbc mode update ivec.
void des_ncbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule sk,
des_cblock *ivec,
int enc);
For historical reasons, des_cbc_encrypt() did not update the
ivec with the value requires so that subsequent calls to
des_cbc_encrypt() would 'chain'. This was needed so that the same
'length' values would not need to be used when decrypting.
des_ncbc_encrypt() does the right thing. It is the same as
des_cbc_encrypt accept that ivec is updates with the correct value
to pass in subsequent calls to des_ncbc_encrypt(). I advise using
des_ncbc_encrypt() instead of des_cbc_encrypt();
void des_xcbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule sk,
des_cblock *ivec,
des_cblock *inw,
des_cblock *outw,
int enc);
This is RSA's DESX mode of DES. It uses inw and outw to
'whiten' the encryption. inw and outw are secret (unlike the iv)
and are as such, part of the key. So the key is sort of 24 bytes.
This is much better than cbc des.
void des_3cbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule sk1,
des_key_schedule sk2,
des_cblock *ivec1,
des_cblock *ivec2,
int enc);
This function is flawed, do not use it. I have left it in the
library because it is used in my des(1) program and will function
correctly when used by des(1). If I removed the function, people
could end up unable to decrypt files.
This routine implements outer triple cbc encryption using 2 ks and
2 ivec's. Use des_ede2_cbc_encrypt() instead.
void des_ede3_cbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule ks1,
des_key_schedule ks2,
des_key_schedule ks3,
des_cblock *ivec,
int enc);
This function implements inner triple CBC DES encryption with 3
keys. What this means is that each 'DES' operation
inside the cbc mode is really an C=E(ks3,D(ks2,E(ks1,M))).
Again, this is cbc mode so an ivec is requires.
This mode is used by SSL.
There is also a des_ede2_cbc_encrypt() that only uses 2
des_key_schedule's, the first being reused for the final
encryption. C=E(ks1,D(ks2,E(ks1,M))). This form of triple DES
is used by the RSAref library.
void des_pcbc_encrypt(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule ks,
des_cblock *ivec,
int enc);
This is Propagating Cipher Block Chaining mode of DES. It is used
by Kerberos v4. It's parameters are the same as des_ncbc_encrypt().
void des_cfb_encrypt(
unsigned char *in,
unsigned char *out,
int numbits,
long length,
des_key_schedule ks,
des_cblock *ivec,
int enc);
Cipher Feedback Back mode of DES. This implementation 'feeds back'
in numbit blocks. The input (and output) is in multiples of numbits
bits. numbits should to be a multiple of 8 bits. Length is the
number of bytes input. If numbits is not a multiple of 8 bits,
the extra bits in the bytes will be considered padding. So if
numbits is 12, for each 2 input bytes, the 4 high bits of the
second byte will be ignored. So to encode 72 bits when using
a numbits of 12 take 12 bytes. To encode 72 bits when using
numbits of 9 will take 16 bytes. To encode 80 bits when using
numbits of 16 will take 10 bytes. etc, etc. This padding will
apply to both input and output.
void des_cfb64_encrypt(
unsigned char *in,
unsigned char *out,
long length,
des_key_schedule ks,
des_cblock *ivec,
int *num,
int enc);
This is one of the more useful functions in this DES library, it
implements CFB mode of DES with 64bit feedback. Why is this
useful you ask? Because this routine will allow you to encrypt an
arbitrary number of bytes, no 8 byte padding. Each call to this
routine will encrypt the input bytes to output and then update ivec
and num. num contains 'how far' we are though ivec. If this does
not make much sense, read more about cfb mode of DES :-).
void des_ede3_cfb64_encrypt(
unsigned char *in,
unsigned char *out,
long length,
des_key_schedule ks1,
des_key_schedule ks2,
des_key_schedule ks3,
des_cblock *ivec,
int *num,
int enc);
Same as des_cfb64_encrypt() accept that the DES operation is
triple DES. As usual, there is a macro for
des_ede2_cfb64_encrypt() which reuses ks1.
void des_ofb_encrypt(
unsigned char *in,
unsigned char *out,
int numbits,
long length,
des_key_schedule ks,
des_cblock *ivec);
This is a implementation of Output Feed Back mode of DES. It is
the same as des_cfb_encrypt() in that numbits is the size of the
units dealt with during input and output (in bits).
void des_ofb64_encrypt(
unsigned char *in,
unsigned char *out,
long length,
des_key_schedule ks,
des_cblock *ivec,
int *num);
The same as des_cfb64_encrypt() except that it is Output Feed Back
mode.
void des_ede3_ofb64_encrypt(
unsigned char *in,
unsigned char *out,
long length,
des_key_schedule ks1,
des_key_schedule ks2,
des_key_schedule ks3,
des_cblock *ivec,
int *num);
Same as des_ofb64_encrypt() accept that the DES operation is
triple DES. As usual, there is a macro for
des_ede2_ofb64_encrypt() which reuses ks1.
int des_read_pw_string(
char *buf,
int length,
char *prompt,
int verify);
This routine is used to get a password from the terminal with echo
turned off. Buf is where the string will end up and length is the
size of buf. Prompt is a string presented to the 'user' and if
verify is set, the key is asked for twice and unless the 2 copies
match, an error is returned. A return code of -1 indicates a
system error, 1 failure due to use interaction, and 0 is success.
unsigned long des_cbc_cksum(
des_cblock *input,
des_cblock *output,
long length,
des_key_schedule ks,
des_cblock *ivec);
This function produces an 8 byte checksum from input that it puts in
output and returns the last 4 bytes as a long. The checksum is
generated via cbc mode of DES in which only the last 8 byes are
kept. I would recommend not using this function but instead using
the EVP_Digest routines, or at least using MD5 or SHA. This
function is used by Kerberos v4 so that is why it stays in the
library.
char *des_fcrypt(
const char *buf,
const char *salt
char *ret);
This is my fast version of the unix crypt(3) function. This version
takes only a small amount of space relative to other fast
crypt() implementations. This is different to the normal crypt
in that the third parameter is the buffer that the return value
is written into. It needs to be at least 14 bytes long. This
function is thread safe, unlike the normal crypt.
char *crypt(
const char *buf,
const char *salt);
This function calls des_fcrypt() with a static array passed as the
third parameter. This emulates the normal non-thread safe semantics
of crypt(3).
void des_string_to_key(
char *str,
des_cblock *key);
This function takes str and converts it into a DES key. I would
recommend using MD5 instead and use the first 8 bytes of output.
When I wrote the first version of these routines back in 1990, MD5
did not exist but I feel these routines are still sound. This
routines is compatible with the one in MIT's libdes.
void des_string_to_2keys(
char *str,
des_cblock *key1,
des_cblock *key2);
This function takes str and converts it into 2 DES keys.
I would recommend using MD5 and using the 16 bytes as the 2 keys.
I have nothing against these 2 'string_to_key' routines, it's just
that if you say that your encryption key is generated by using the
16 bytes of an MD5 hash, every-one knows how you generated your
keys.
int des_read_password(
des_cblock *key,
char *prompt,
int verify);
This routine combines des_read_pw_string() with des_string_to_key().
int des_read_2passwords(
des_cblock *key1,
des_cblock *key2,
char *prompt,
int verify);
This routine combines des_read_pw_string() with des_string_to_2key().
void des_random_seed(
des_cblock key);
This routine sets a starting point for des_random_key().
void des_random_key(
des_cblock ret);
This function return a random key. Make sure to 'seed' the random
number generator (with des_random_seed()) before using this function.
I personally now use a MD5 based random number system.
int des_enc_read(
int fd,
char *buf,
int len,
des_key_schedule ks,
des_cblock *iv);
This function will write to a file descriptor the encrypted data
from buf. This data will be preceded by a 4 byte 'byte count' and
will be padded out to 8 bytes. The encryption is either CBC of
PCBC depending on the value of des_rw_mode. If it is DES_PCBC_MODE,
pcbc is used, if DES_CBC_MODE, cbc is used. The default is to use
DES_PCBC_MODE.
int des_enc_write(
int fd,
char *buf,
int len,
des_key_schedule ks,
des_cblock *iv);
This routines read stuff written by des_enc_read() and decrypts it.
I have used these routines quite a lot but I don't believe they are
suitable for non-blocking io. If you are after a full
authentication/encryption over networks, have a look at SSL instead.
unsigned long des_quad_cksum(
des_cblock *input,
des_cblock *output,
long length,
int out_count,
des_cblock *seed);
This is a function from Kerberos v4 that is not anything to do with
DES but was needed. It is a cksum that is quicker to generate than
des_cbc_cksum(); I personally would use MD5 routines now.
=====
Modes of DES
Quite a bit of the following information has been taken from
AS 2805.5.2
Australian Standard
Electronic funds transfer - Requirements for interfaces,
Part 5.2: Modes of operation for an n-bit block cipher algorithm
Appendix A
There are several different modes in which DES can be used, they are
as follows.
Electronic Codebook Mode (ECB) (des_ecb_encrypt())
- 64 bits are enciphered at a time.
- The order of the blocks can be rearranged without detection.
- The same plaintext block always produces the same ciphertext block
(for the same key) making it vulnerable to a 'dictionary attack'.
- An error will only affect one ciphertext block.
Cipher Block Chaining Mode (CBC) (des_cbc_encrypt())
- a multiple of 64 bits are enciphered at a time.
- The CBC mode produces the same ciphertext whenever the same
plaintext is encrypted using the same key and starting variable.
- The chaining operation makes the ciphertext blocks dependent on the
current and all preceding plaintext blocks and therefore blocks can not
be rearranged.
- The use of different starting variables prevents the same plaintext
enciphering to the same ciphertext.
- An error will affect the current and the following ciphertext blocks.
Cipher Feedback Mode (CFB) (des_cfb_encrypt())
- a number of bits (j) <= 64 are enciphered at a time.
- The CFB mode produces the same ciphertext whenever the same
plaintext is encrypted using the same key and starting variable.
- The chaining operation makes the ciphertext variables dependent on the
current and all preceding variables and therefore j-bit variables are
chained together and can not be rearranged.
- The use of different starting variables prevents the same plaintext
enciphering to the same ciphertext.
- The strength of the CFB mode depends on the size of k (maximal if
j == k). In my implementation this is always the case.
- Selection of a small value for j will require more cycles through
the encipherment algorithm per unit of plaintext and thus cause
greater processing overheads.
- Only multiples of j bits can be enciphered.
- An error will affect the current and the following ciphertext variables.
Output Feedback Mode (OFB) (des_ofb_encrypt())
- a number of bits (j) <= 64 are enciphered at a time.
- The OFB mode produces the same ciphertext whenever the same
plaintext enciphered using the same key and starting variable. More
over, in the OFB mode the same key stream is produced when the same
key and start variable are used. Consequently, for security reasons
a specific start variable should be used only once for a given key.
- The absence of chaining makes the OFB more vulnerable to specific attacks.
- The use of different start variables values prevents the same
plaintext enciphering to the same ciphertext, by producing different
key streams.
- Selection of a small value for j will require more cycles through
the encipherment algorithm per unit of plaintext and thus cause
greater processing overheads.
- Only multiples of j bits can be enciphered.
- OFB mode of operation does not extend ciphertext errors in the
resultant plaintext output. Every bit error in the ciphertext causes
only one bit to be in error in the deciphered plaintext.
- OFB mode is not self-synchronising. If the two operation of
encipherment and decipherment get out of synchronism, the system needs
to be re-initialised.
- Each re-initialisation should use a value of the start variable
different from the start variable values used before with the same
key. The reason for this is that an identical bit stream would be
produced each time from the same parameters. This would be
susceptible to a ' known plaintext' attack.
Triple ECB Mode (des_ecb3_encrypt())
- Encrypt with key1, decrypt with key2 and encrypt with key3 again.
- As for ECB encryption but increases the key length to 168 bits.
There are theoretic attacks that can be used that make the effective
key length 112 bits, but this attack also requires 2^56 blocks of
memory, not very likely, even for the NSA.
- If both keys are the same it is equivalent to encrypting once with
just one key.
- If the first and last key are the same, the key length is 112 bits.
There are attacks that could reduce the key space to 55 bit's but it
requires 2^56 blocks of memory.
- If all 3 keys are the same, this is effectively the same as normal
ecb mode.
Triple CBC Mode (des_ede3_cbc_encrypt())
- Encrypt with key1, decrypt with key2 and then encrypt with key3.
- As for CBC encryption but increases the key length to 168 bits with
the same restrictions as for triple ecb mode.

[

] ]
.SH DESCRIPTION
.B des
encrypts and decrypts data using the
Data Encryption Standard algorithm.
One of
.B \-e, \-E
(for encrypt) or
.B \-d, \-D
(for decrypt) must be specified.
It is also possible to use
.B \-c
or
.B \-C
in conjunction or instead of the a encrypt/decrypt option to generate
a 16 character hexadecimal checksum, generated via the
.I des_cbc_cksum.
.LP
Two standard encryption modes are supported by the
.B des
program, Cipher Block Chaining (the default) and Electronic Code Book
(specified with
.B \-b
).
.LP
The key used for the DES
algorithm is obtained by prompting the user unless the
.B `\-k
.I key'
option is given.
If the key is an argument to the
.B des
command, it is potentially visible to users executing
.BR ps (1)
or a derivative. To minimise this possibility,
.B des
takes care to destroy the key argument immediately upon entry.
If your shell keeps a history file be careful to make sure it is not
world readable.
.LP
Since this program attempts to maintain compatability with sunOS's
des(1) command, there are 2 different methods used to convert the user
supplied key to a des key.
Whenever and one or more of
.B \-E, \-D, \-C
or
.B \-3
options are used, the key conversion procedure will not be compatible
with the sunOS des(1) version but will use all the user supplied
character to generate the des key.
.B des
command reads from standard input unless
.I input-file
is specified and writes to standard output unless
.I output-file
is given.
.SH OPTIONS
.TP
.B \-b
Select ECB
(eight bytes at a time) encryption mode.
.TP
.B \-3
Encrypt using triple encryption.
By default triple cbc encryption is used but if the
.B \-b
option is used then triple ecb encryption is performed.
If the key is less than 8 characters long, the flag has no effect.
.TP
.B \-e
Encrypt data using an 8 byte key in a manner compatible with sunOS
des(1).
.TP
.B \-E
Encrypt data using a key of nearly unlimited length (1024 bytes).
This will product a more secure encryption.
.TP
.B \-d
Decrypt data that was encrypted with the \-e option.
.TP
.B \-D
Decrypt data that was encrypted with the \-E option.
.TP
.B \-c
Generate a 16 character hexadecimal cbc checksum and output this to
stderr.
If a filename was specified after the
.B \-c
option, the checksum is output to that file.
The checksum is generated using a key generated in a sunOS compatible
manner.
.TP
.B \-C
A cbc checksum is generated in the same manner as described for the
.B \-c
option but the DES key is generated in the same manner as used for the
.B \-E
and
.B \-D
options
.TP
.B \-f
Does nothing - allowed for compatibility with sunOS des(1) command.
.TP
.B \-s
Does nothing - allowed for compatibility with sunOS des(1) command.
.TP
.B "\-k \fIkey\fP"
Use the encryption
.I key
specified.
.TP
.B "\-h"
The
.I key
is assumed to be a 16 character hexadecimal number.
If the
.B "\-3"
option is used the key is assumed to be a 32 character hexadecimal
number.
.TP
.B \-u
This flag is used to read and write uuencoded files. If decrypting,
the input file is assumed to contain uuencoded, DES encrypted data.
If encrypting, the characters following the -u are used as the name of
the uuencoded file to embed in the begin line of the uuencoded
output. If there is no name specified after the -u, the name text.des
will be embedded in the header.
.SH SEE ALSO
.B ps (1)
.B des_crypt(3)
.SH BUGS
.LP
The problem with using the
.B -e
option is the short key length.
It would be better to use a real 56-bit key rather than an
ASCII-based 56-bit pattern. Knowing that the key was derived from ASCII
radically reduces the time necessary for a brute-force cryptographic attack.
My attempt to remove this problem is to add an alternative text-key to
DES-key function. This alternative function (accessed via
.B -E, -D, -S
and
.B -3
)
uses DES to help generate the key.
.LP
Be carefully when using the -u option. Doing des -ud <filename> will
not decrypt filename (the -u option will gobble the d option).
.LP
The VMS operating system operates in a world where files are always a
multiple of 512 bytes. This causes problems when encrypted data is
send from unix to VMS since a 88 byte file will suddenly be padded
with 424 null bytes. To get around this problem, use the -u option
to uuencode the data before it is send to the VMS system.

# 11 April 1996 - patched to circumvent Perl 5 (through 5.002) problem
# with sign-extension on right shift operations.
# Ed Kubaitis - ejk@uiuc.edu
#
# eay - 92/08/31 - I think I have fixed all problems for 64bit
# versions of perl but I could be wrong since I have not tested it yet :-).
#
# This is an implementation of DES in perl.
# The two routines (des_set_key and des_ecb_encrypt)
# take 8 byte objects as arguments.
#
# des_set_key takes an 8 byte string as a key and returns a key schedule
# for use in calls to des_ecb_encrypt.
# des_ecb_encrypt takes three arguments, the first is a key schedule
# (make sure to pass it by reference with the *), the second is 1
# to encrypt, 0 to decrypt. The third argument is an 8 byte object
# to encrypt. The function returns an 8 byte object that has been
# DES encrypted.
#
# example:
# require 'des.pl'
#
# $key =pack("C8",0x12,0x23,0x45,0x67,0x89,0xab,0xcd,0xef);
# @ks= &des_set_key($key);

.SH DESCRIPTION
This library contains a fast implementation of the DES encryption
algorithm.
.PP
There are two phases to the use of DES encryption.
The first is the generation of a
.I des_key_schedule
from a key,
the second is the actual encryption.
A des key is of type
.I des_cblock.
This type is made from 8 characters with odd parity.
The least significant bit in the character is the parity bit.
The key schedule is an expanded form of the key; it is used to speed the
encryption process.
.PP
.I des_read_password
writes the string specified by prompt to the standard output,
turns off echo and reads an input string from standard input
until terminated with a newline.
If verify is non-zero, it prompts and reads the input again and verifies
that both entered passwords are the same.
The entered string is converted into a des key by using the
.I des_string_to_key
routine.
The new key is placed in the
.I des_cblock
that was passed (by reference) to the routine.
If there were no errors,
.I des_read_password
returns 0,
-1 is returned if there was a terminal error and 1 is returned for
any other error.
.PP
.I des_read_2password
operates in the same way as
.I des_read_password
except that it generates 2 keys by using the
.I des_string_to_2key
function.
.PP
.I des_read_pw_string
is called by
.I des_read_password
to read and verify a string from a terminal device.
The string is returned in
.I buf.
The size of
.I buf
is passed to the routine via the
.I length
parameter.
.PP
.I des_string_to_key
converts a string into a valid des key.
.PP
.I des_string_to_2key
converts a string into 2 valid des keys.
This routine is best suited for used to generate keys for use with
.I des_3ecb_encrypt.
.PP
.I des_random_key
returns a random key that is made of a combination of process id,
time and an increasing counter.
.PP
Before a des key can be used it is converted into a
.I des_key_schedule
via the
.I des_set_key
routine.
If the
.I des_check_key
flag is non-zero,
.I des_set_key
will check that the key passed is of odd parity and is not a week or
semi-weak key.
If the parity is wrong,
then -1 is returned.
If the key is a weak key,
then -2 is returned.
If an error is returned,
the key schedule is not generated.
.PP
.I des_key_sched
is another name for the
.I des_set_key
function.
.PP
The following routines mostly operate on an input and output stream of
.I des_cblock's.
.PP
.I des_ecb_encrypt
is the basic DES encryption routine that encrypts or decrypts a single 8-byte
.I des_cblock
in
.I electronic code book
mode.
It always transforms the input data, pointed to by
.I input,
into the output data,
pointed to by the
.I output
argument.
If the
.I encrypt
argument is non-zero (DES_ENCRYPT),
the
.I input
(cleartext) is encrypted in to the
.I output
(ciphertext) using the key_schedule specified by the
.I schedule
argument,
previously set via
.I des_set_key.
If
.I encrypt
is zero (DES_DECRYPT),
the
.I input
(now ciphertext)
is decrypted into the
.I output
(now cleartext).
Input and output may overlap.
No meaningful value is returned.
.PP
.I des_3ecb_encrypt
encrypts/decrypts the
.I input
block by using triple ecb DES encryption.
This involves encrypting the input with
.I ks1,
decryption with the key schedule
.I ks2,
and then encryption with the first again.
This routine greatly reduces the chances of brute force breaking of
DES and has the advantage of if
.I ks1
and
.I ks2
are the same, it is equivalent to just encryption using ecb mode and
.I ks1
as the key.
.PP
.I des_cbc_encrypt
encrypts/decrypts using the
.I cipher-block-chaining
mode of DES.
If the
.I encrypt
argument is non-zero,
the routine cipher-block-chain encrypts the cleartext data pointed to by the
.I input
argument into the ciphertext pointed to by the
.I output
argument,
using the key schedule provided by the
.I schedule
argument,
and initialisation vector provided by the
.I ivec
argument.
If the
.I length
argument is not an integral multiple of eight bytes,
the last block is copied to a temporary area and zero filled.
The output is always
an integral multiple of eight bytes.
To make multiple cbc encrypt calls on a large amount of data appear to
be one
.I des_cbc_encrypt
call, the
.I ivec
of subsequent calls should be the last 8 bytes of the output.
.PP
.I des_3cbc_encrypt
encrypts/decrypts the
.I input
block by using triple cbc DES encryption.
This involves encrypting the input with key schedule
.I ks1,
decryption with the key schedule
.I ks2,
and then encryption with the first again.
2 initialisation vectors are required,
.I ivec1
and
.I ivec2.
Unlike
.I des_cbc_encrypt,
these initialisation vectors are modified by the subroutine.
This routine greatly reduces the chances of brute force breaking of
DES and has the advantage of if
.I ks1
and
.I ks2
are the same, it is equivalent to just encryption using cbc mode and
.I ks1
as the key.
.PP
.I des_pcbc_encrypt
encrypt/decrypts using a modified block chaining mode.
It provides better error propagation characteristics than cbc
encryption.
.PP
.I des_cfb_encrypt
encrypt/decrypts using cipher feedback mode. This method takes an
array of characters as input and outputs and array of characters. It
does not require any padding to 8 character groups. Note: the ivec
variable is changed and the new changed value needs to be passed to
the next call to this function. Since this function runs a complete
DES ecb encryption per numbits, this function is only suggested for
use when sending small numbers of characters.
.PP
.I des_ofb_encrypt
encrypt using output feedback mode. This method takes an
array of characters as input and outputs and array of characters. It
does not require any padding to 8 character groups. Note: the ivec
variable is changed and the new changed value needs to be passed to
the next call to this function. Since this function runs a complete
DES ecb encryption per numbits, this function is only suggested for
use when sending small numbers of characters.
.PP
.I des_cbc_cksum
produces an 8 byte checksum based on the input stream (via cbc encryption).
The last 4 bytes of the checksum is returned and the complete 8 bytes is
placed in
.I output.
.PP
.I des_quad_cksum
returns a 4 byte checksum from the input bytes.
The algorithm can be iterated over the input,
depending on
.I out_count,
1, 2, 3 or 4 times.
If
.I output
is non-NULL,
the 8 bytes generated by each pass are written into
.I output.
.PP
.I des_enc_write
is used to write
.I len
bytes
to file descriptor
.I fd
from buffer
.I buf.
The data is encrypted via
.I pcbc_encrypt
(default) using
.I sched
for the key and
.I iv
as a starting vector.
The actual data send down
.I fd
consists of 4 bytes (in network byte order) containing the length of the
following encrypted data. The encrypted data then follows, padded with random
data out to a multiple of 8 bytes.
.PP
.I des_enc_read
is used to read
.I len
bytes
from file descriptor
.I fd
into buffer
.I buf.
The data being read from
.I fd
is assumed to have come from
.I des_enc_write
and is decrypted using
.I sched
for the key schedule and
.I iv
for the initial vector.
The
.I des_enc_read/des_enc_write
pair can be used to read/write to files, pipes and sockets.
I have used them in implementing a version of rlogin in which all
data is encrypted.
.PP
.I des_rw_mode
is used to specify the encryption mode to use with
.I des_enc_read
and
.I des_end_write.
If set to
.I DES_PCBC_MODE
(the default), des_pcbc_encrypt is used.
If set to
.I DES_CBC_MODE
des_cbc_encrypt is used.
These two routines and the variable are not part of the normal MIT library.
.PP
.I des_set_odd_parity
sets the parity of the passed
.I key
to odd. This routine is not part of the standard MIT library.
.PP
.I des_is_weak_key
returns 1 is the passed key is a weak key (pick again :-),
0 if it is ok.
This routine is not part of the standard MIT library.
.PP
.I crypt
is a replacement for the normal system crypt.
It is much faster than the system crypt.
.PP
.SH FILES
/usr/include/des.h
.br
/usr/lib/libdes.a
.PP
The encryption routines have been tested on 16bit, 32bit and 64bit
machines of various endian and even works under VMS.
.PP
.SH BUGS
.PP
If you think this manual is sparse,
read the des_crypt(3) manual from the MIT kerberos (or bones outside
of the USA) distribution.
.PP
.I des_cfb_encrypt
and
.I des_ofb_encrypt
operates on input of 8 bits. What this means is that if you set
numbits to 12, and length to 2, the first 12 bits will come from the 1st
input byte and the low half of the second input byte. The second 12
bits will have the low 8 bits taken from the 3rd input byte and the
top 4 bits taken from the 4th input byte. The same holds for output.
This function has been implemented this way because most people will
be using a multiple of 8 and because once you get into pulling bytes input
bytes apart things get ugly!
.PP
.I des_read_pw_string
is the most machine/OS dependent function and normally generates the
most problems when porting this code.
.PP
.I des_string_to_key
is probably different from the MIT version since there are lots
of fun ways to implement one-way encryption of a text string.
.PP
The routines are optimised for 32 bit machines and so are not efficient
on IBM PCs.
.PP
NOTE: extensive work has been done on this library since this document
was origionally written. Please try to read des.doc from the libdes
distribution since it is far more upto date and documents more of the
functions. Libdes is now also being shipped as part of SSLeay, a
general cryptographic library that amonst other things implements
netscapes SSL protocoll. The most recent version can be found in
SSLeay distributions.

The output has been subject to swaps of the form

different words. The main trick is to remember that
t=((l>>size)^r)&(mask);
r^=t;
l^=(t<<size);
can be used to swap and move bits between words.
So l = 0 1 2 3 r = 16 17 18 19

Thanks for hints from Richard Outerbridge - he told me IP&FP
could be done in 15 xor, 10 shifts and 5 ands.
When I finally started to think of the problem in 2D
I first got ~42 operations without xors. When I remembered
how to use xors :-) I got it to its final state.

The output has been subject to swaps of the form
0 1 -> 3 1 but the odd and even bits have been put into
2 3 2 0
different words. The main trick is to remember that
t=((l>>size)^r)&(mask);
r^=t;
l^=(t<<size);
can be used to swap and move bits between words.
So l = 0 1 2 3 r = 16 17 18 19

8 9 10 11 24 25 26 27

t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19
6^20 7^21 -- -- 4 5 20 21 6 7 22 23

14^28 15^29 -- -- 12 13 28 29 14 15 28 29
Thanks for hints from Richard Outerbridge - he told me IP&FP
could be done in 15 xor, 10 shifts and 5 ands.
When I finally started to think of the problem in 2D
I first got ~42 operations without xors. When I remembered
how to use xors :-) I got it to its final state.
