(Including all changes for FreeBSD - importing the original eBones distribution would be too complex at this stage, since I don't have access to Piero's CVS.) (If you want to include eBones in your system, don't forget to include MAKE_EBONES in /etc/make.conf.) (This stuff is now also suppable from braae.ru.ac.za.) Bones originally from MIT SIPB. Original port to FreeBSD 1.x by Piero Serini. Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet. Nice bug fixes from Doug Rabson.

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
|
