The primary ftp site for this library is
|
|
ftp://ftp.psy.uq.oz.au/pub/Crypto/DES/libdes-x.xx.tar.gz
|
|
libdes is now also shipped with SSLeay. Primary ftp site of
|
|
ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.xx.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, 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.
