1 Fixed the weak key values which were wrong :-(
2 Defining SIGACTION causes sigaction() to be used instead of signal().
3 SIGUSR1/SIGUSR2 are no longer mapped in the read tty stuff because it
4 can cause problems. This should hopefully not affect normal
5 applications.
7 Version 4.04
8 Fixed a few tests in destest. Also added x86 assember for
9 des_ncbc_encrypt() which is the standard cbc mode function.
10 This makes a very very large performace difference.
11 Ariel Glenn ariel@columbia.edu reports that the terminal
12 'turn echo off' can return (errno == EINVAL) under solaris
13 when redirection is used. So I now catch that as well as ENOTTY.
16 Version 4.03
17 Left a static out of enc_write.c, which caused to buffer to be
18 continiously malloc()ed. Does anyone use these functions? I keep
19 on feeling like removing them since I only had these in there
20 for a version of kerberised login. Anyway, this was pointed out
21 by Theo de Raadt <deraadt@cvs.openbsd.org>
22 The 'n' bit ofb code was wrong, it was not shifting the shift
23 register. It worked correctly for n == 64. Thanks to
24 Gigi Ankeny <Gigi.Ankeny@Eng.Sun.COM> for pointing this one out.
26 Version 4.02
27 I was doing 'if (memcmp(weak_keys[i],key,sizeof(key)) == 0)'
28 when checking for weak keys which is wrong :-(, pointed out by
29 Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>.
31 Version 4.01
32 Even faster inner loop in the DES assembler for x86 and a modification
33 for IP/FP which is faster on x86. Both of these changes are
34 from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His
35 changes make the assembler run %40 faster on a pentium. This is just
36 a case of getting the instruction sequence 'just right'.
37 All credit to 'Svend' :-)
38 Quite a few special x86 'make' targets.
39 A libdes-l (lite) distribution.
41 Version 4.00
42 After a bit of a pause, I'll up the major version number since this
43 is mostly a performace release. I've added x86 assembler and
44 added more options for performance. A %28 speedup for gcc
45 on a pentium and the assembler is a %50 speedup.
46 MIPS CPU's, sparc and Alpha are the main CPU's with speedups.
47 Run des_opts to work out which options should be used.
48 DES_RISC1/DES_RISC2 use alternative inner loops which use
49 more registers but should give speedups on any CPU that does
50 dual issue (pentium). DES_UNROLL unrolls the inner loop,
51 which costs in code size.
53 Version 3.26
54 I've finally removed one of the shifts in D_ENCRYPT. This
55 meant I've changed the des_SPtrans table (spr.h), the set_key()
56 function and some things in des_enc.c. This has definitly
57 made things faster :-). I've known about this one for some
58 time but I've been too lazy to follow it up :-).
59 Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^..
60 instead of L^=((..)|(..)|(..).. This should save a register at
61 least.
62 Assember for x86. The file to replace is des_enc.c, which is replaced
63 by one of the assembler files found in asm. Look at des/asm/readme
64 for more info.
66 /* Modification to fcrypt so it can be compiled to support
67 HPUX 10.x's long password format, define -DLONGCRYPT to use this.
68 Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */
70 SIGWINCH case put in des_read_passwd() so the function does not
71 'exit' if this function is recieved.
73 Version 3.25 17/07/96
74 Modified read_pwd.c so that stdin can be read if not a tty.
75 Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches.
76 des_init_random_number_generator() shortened due to VMS linker
77 limits.
78 Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2
79 8 byte quantites xored before and after encryption.
80 des_xcbc_encryption() - the name is funny to preserve the des_
81 prefix on all functions.
83 Version 3.24 20/04/96
84 The DES_PTR macro option checked and used by SSLeay configuration
86 Version 3.23 11/04/96
87 Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha,
88 it gives a %20 speedup :-)
89 Fixed the problem with des.pl under perl5. The patches were
90 sent by Ed Kubaitis (ejk@uiuc.edu).
91 if fcrypt.c, changed values to handle illegal salt values the way
92 normal crypt() implementations do. Some programs apparently use
93 them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se>
95 Version 3.22 29/11/95
96 Bug in des(1), an error with the uuencoding stuff when the
97 'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au>
98 for the patch.
100 Version 3.21 22/11/95
101 After some emailing back and forth with
102 Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things
103 and in a future version I will probably put in some of the
104 optimisation he suggested for use with the DES_USE_PTR option.
105 Extra routines from Mark Murray <mark@grondar.za> for use in
106 freeBSD. They mostly involve random number generation for use
107 with kerberos. They involve evil machine specific system calls
108 etc so I would normally suggest pushing this stuff into the
109 application and/or using RAND_seed()/RAND_bytes() if you are
110 using this DES library as part of SSLeay.
111 Redone the read_pw() function so that it is cleaner and
112 supports termios, thanks to Sameer Parekh <sameer@c2.org>
113 for the initial patches for this.
114 Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been
115 done just to make things more consistent.
116 I have also now added triple DES versions of cfb and ofb.
118 Version 3.20
119 Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com,
120 my des_random_seed() function was only copying 4 bytes of the
121 passed seed into the init structure. It is now fixed to copy 8.
122 My own suggestion is to used something like MD5 :-)
124 Version 3.19
125 While looking at my code one day, I though, why do I keep on
126 calling des_encrypt(in,out,ks,enc) when every function that
127 calls it has in and out the same. So I dropped the 'out'
128 parameter, people should not be using this function.
130 Version 3.18 30/08/95
131 Fixed a few bit with the distribution and the filenames.
132 3.17 had been munged via a move to DOS and back again.
133 NO CODE CHANGES
135 Version 3.17 14/07/95
136 Fixed ede3 cbc which I had broken in 3.16. I have also
137 removed some unneeded variables in 7-8 of the routines.
139 Version 3.16 26/06/95
140 Added des_encrypt2() which does not use IP/FP, used by triple
141 des routines. Tweaked things a bit elsewhere. %13 speedup on
142 sparc and %6 on a R4400 for ede3 cbc mode.
144 Version 3.15 06/06/95
145 Added des_ncbc_encrypt(), it is des_cbc mode except that it is
146 'normal' and copies the new iv value back over the top of the
147 passed parameter.
148 CHANGED des_ede3_cbc_encrypt() so that it too now overwrites
149 the iv. THIS WILL BREAK EXISTING CODE, but since this function
150 only new, I feel I can change it, not so with des_cbc_encrypt :-(.
151 I need to update the documentation.
153 Version 3.14 31/05/95
154 New release upon the world, as part of my SSL implementation.
155 New copyright and usage stuff. Basically free for all to use
156 as long as you say it came from me :-)
158 Version 3.13 31/05/95
159 A fix in speed.c, if HZ is not defined, I set it to 100.0
160 which is reasonable for most unixes except SunOS 4.x.
161 I now have a #ifdef sun but timing for SunOS 4.x looked very
162 good :-(. At my last job where I used SunOS 4.x, it was
163 defined to be 60.0 (look at the old INSTALL documentation), at
164 the last release had it changed to 100.0 since I now work with
165 Solaris2 and SVR4 boxes.
166 Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this
167 one out.
169 Version 3.12 08/05/95
170 As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>,
171 my D_ENCRYPT macro in crypt() had an un-necessary variable.
172 It has been removed.
174 Version 3.11 03/05/95
175 Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys
176 and one iv. It is a standard and I needed it for my SSL code.
177 It makes more sense to use this for triple DES than
178 3cbc_encrypt(). I have also added (or should I say tested :-)
179 cfb64_encrypt() which is cfb64 but it will encrypt a partial
180 number of bytes - 3 bytes in 3 bytes out. Again this is for
181 my SSL library, as a form of encryption to use with SSL
182 telnet.
184 Version 3.10 22/03/95
185 Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls
186 to cbc3_encrypt, the 2 iv values that were being returned to
187 be used in the next call were reversed :-(.
188 Many thanks to Bill Wade <wade@Stoner.COM> for pointing out
189 this error.
191 Version 3.09 01/02/95
192 Fixed des_random_key to far more random, it was rather feeble
193 with regards to picking the initial seed. The problem was
194 pointed out by Olaf Kirch <okir@monad.swb.de>.
196 Version 3.08 14/12/94
197 Added Makefile.PL so libdes can be built into perl5.
198 Changed des_locl.h so RAND is always defined.
200 Version 3.07 05/12/94
201 Added GNUmake and stuff so the library can be build with
202 glibc.
204 Version 3.06 30/08/94
205 Added rpc_enc.c which contains _des_crypt. This is for use in
206 secure_rpc v 4.0
207 Finally fixed the cfb_enc problems.
208 Fixed a few parameter parsing bugs in des (-3 and -b), thanks
209 to Rob McMillan <R.McMillan@its.gu.edu.au>
211 Version 3.05 21/04/94
212 for unsigned long l; gcc does not produce ((l>>34) == 0)
213 This causes bugs in cfb_enc.
214 Thanks to Hadmut Danisch <danisch@ira.uka.de>
216 Version 3.04 20/04/94
217 Added a version number to des.c and libdes.a
219 Version 3.03 12/01/94
220 Fixed a bug in non zero iv in 3cbc_enc.
222 Version 3.02 29/10/93
223 I now work in a place where there are 6+ architectures and 14+
224 OS versions :-).
225 Fixed TERMIO definition so the most sys V boxes will work :-)
227 Release upon comp.sources.misc
228 Version 3.01 08/10/93
229 Added des_3cbc_encrypt()
231 Version 3.00 07/10/93
232 Fixed up documentation.
233 quad_cksum definitely compatible with MIT's now.
235 Version 2.30 24/08/93
236 Triple DES now defaults to triple cbc but can do triple ecb
237 with the -b flag.
238 Fixed some MSDOS uuen/uudecoding problems, thanks to
239 Added prototypes.
241 Version 2.22 29/06/93
242 Fixed a bug in des_is_weak_key() which stopped it working :-(
243 thanks to engineering@MorningStar.Com.
245 Version 2.21 03/06/93
246 des(1) with no arguments gives quite a bit of help.
247 Added -c (generate ckecksum) flag to des(1).
248 Added -3 (triple DES) flag to des(1).
249 Added cfb and ofb routines to the library.
251 Version 2.20 11/03/93
252 Added -u (uuencode) flag to des(1).
253 I have been playing with byte order in quad_cksum to make it
254 compatible with MIT's version. All I can say is avid this
255 function if possible since MIT's output is endian dependent.
257 Version 2.12 14/10/92
258 Added MSDOS specific macro in ecb_encrypt which gives a %70
259 speed up when the code is compiled with turbo C.
261 Version 2.11 12/10/92
262 Speedup in set_key (recoding of PC-1)
263 I now do it in 47 simple operations, down from 60.
264 Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov)
265 for motivating me to look for a faster system :-)
266 The speedup is probably less that 1% but it is still 13
267 instructions less :-).
269 Version 2.10 06/10/92
270 The code now works on the 64bit ETA10 and CRAY without modifications or
271 #defines. I believe the code should work on any machine that
272 defines long, int or short to be 8 bytes long.
273 Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu)
274 for helping me fix the code to run on 64bit machines (he had
275 access to an ETA10).
276 Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov>
277 for testing the routines on a CRAY.
278 read_password.c has been renamed to read_passwd.c
279 string_to_key.c has been renamed to string2key.c
281 Version 2.00 14/09/92
282 Made mods so that the library should work on 64bit CPU's.
283 Removed all my uchar and ulong defs. To many different
284 versions of unix define them in their header files in too many
285 different combinations :-)
286 IRIX - Sillicon Graphics mods (mostly in read_password.c).
287 Thanks to Andrew Daviel (advax@erich.triumf.ca)
289 Version 1.99 26/08/92
290 Fixed a bug or 2 in enc_read.c
291 Fixed a bug in enc_write.c
292 Fixed a pseudo bug in fcrypt.c (very obscure).
294 Version 1.98 31/07/92
295 Support for the ETA10. This is a strange machine that defines
296 longs and ints as 8 bytes and shorts as 4 bytes.
297 Since I do evil things with long * that assume that they are 4
298 bytes. Look in the Makefile for the option to compile for
299 this machine. quad_cksum appears to have problems but I
300 will don't have the time to fix it right now, and this is not
301 a function that uses DES and so will not effect the main uses
302 of the library.
304 Version 1.97 20/05/92 eay
305 Fixed the Imakefile and made some changes to des.h to fix some
306 problems when building this package with Kerberos v 4.
308 Version 1.96 18/05/92 eay
309 Fixed a small bug in string_to_key() where problems could
310 occur if des_check_key was set to true and the string
311 generated a weak key.
313 Patch2 posted to comp.sources.misc
314 Version 1.95 13/05/92 eay
315 Added an alternative version of the D_ENCRYPT macro in
316 ecb_encrypt and fcrypt. Depending on the compiler, one version or the
317 other will be faster. This was inspired by
318 Dana How <how@isl.stanford.edu>, and her pointers about doing the
319 *(ulong *)((uchar *)ptr+(value&0xfc))
320 vs
321 ptr[value&0x3f]
322 to stop the C compiler doing a <<2 to convert the long array index.
324 Version 1.94 05/05/92 eay
325 Fixed an incompatibility between my string_to_key and the MIT
326 version. When the key is longer than 8 chars, I was wrapping
327 with a different method. To use the old version, define
328 OLD_STR_TO_KEY in the makefile. Thanks to
329 viktor@newsu.shearson.com (Viktor Dukhovni).
331 Version 1.93 28/04/92 eay
332 Fixed the VMS mods so that echo is now turned off in
333 read_password. Thanks again to brennan@coco.cchs.su.oz.AU.
334 MSDOS support added. The routines can be compiled with
335 Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined.
337 Patch1 posted to comp.sources.misc
338 Version 1.92 13/04/92 eay
339 Changed D_ENCRYPT so that the rotation of R occurs outside of
340 the loop. This required rotating all the longs in sp.h (now
341 called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM>
342 speed.c has been changed so it will work without SIGALRM. If
343 times(3) is not present it will try to use ftime() instead.
345 Version 1.91 08/04/92 eay
346 Added -E/-D options to des(1) so it can use string_to_key.
347 Added SVR4 mods suggested by witr@rwwa.COM
348 Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If
349 anyone knows how to turn of tty echo in VMS please tell me or
350 implement it yourself :-).
351 Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS
352 does not like IN/OUT being used.
354 Libdes posted to comp.sources.misc
355 Version 1.9 24/03/92 eay
356 Now contains a fast small crypt replacement.
357 Added des(1) command.
358 Added des_rw_mode so people can use cbc encryption with
359 enc_read and enc_write.
361 Version 1.8 15/10/91 eay
362 Bug in cbc_cksum.
363 Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this
364 one out.
366 Version 1.7 24/09/91 eay
367 Fixed set_key :-)
368 set_key is 4 times faster and takes less space.
369 There are a few minor changes that could be made.
371 Version 1.6 19/09/1991 eay
372 Finally go IP and FP finished.
373 Now I need to fix set_key.
374 This version is quite a bit faster that 1.51
376 Version 1.52 15/06/1991 eay
377 20% speedup in ecb_encrypt by changing the E bit selection
378 to use 2 32bit words. This also required modification of the
379 sp table. There is still a way to speedup the IP and IP-1
380 (hints from outer@sq.com) still working on this one :-(.
382 Version 1.51 07/06/1991 eay
383 Faster des_encrypt by loop unrolling
384 Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu)
386 Version 1.50 28/05/1991 eay
387 Optimised the code a bit more for the sparc. I have improved the
388 speed of the inner des_encrypt by speeding up the initial and
389 final permutations.
391 Version 1.40 23/10/1990 eay
392 Fixed des_random_key, it did not produce a random key :-(
394 Version 1.30 2/10/1990 eay
395 Have made des_quad_cksum the same as MIT's, the full package
396 should be compatible with MIT's
397 Have tested on a DECstation 3100
398 Still need to fix des_set_key (make it faster).
399 Does des_cbc_encrypts at 70.5k/sec on a 3100.
401 Version 1.20 18/09/1990 eay
402 Fixed byte order dependencies.
403 Fixed (I hope) all the word alignment problems.
404 Speedup in des_ecb_encrypt.
406 Version 1.10 11/09/1990 eay
407 Added des_enc_read and des_enc_write.
408 Still need to fix des_quad_cksum.
409 Still need to document des_enc_read and des_enc_write.
411 Version 1.00 27/08/1990 eay
