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
