-Release apon comp.sources.misc
-Version 3.01 08/10/93
- Added des_3cbc_encrypt()
-
-Version 3.00 07/10/93
- Fixed up documentation.
- quad_cksum definitly compatable with MIT's now.
-
-Version 2.30 24/08/93
- Tripple DES now defaults to tripple cbc but can do tripple 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 (tripple 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 aviod 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
- Optimized 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
