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. | ||
6 | |||
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. | ||
14 | |||
15 | |||
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. | ||
25 | |||
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>. | ||
30 | |||
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. | ||
40 | |||
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. | ||
52 | |||
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. | ||
65 | |||
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>. */ | ||
69 | |||
70 | SIGWINCH case put in des_read_passwd() so the function does not | ||
71 | 'exit' if this function is recieved. | ||
72 | |||
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. | ||
82 | |||
83 | Version 3.24 20/04/96 | ||
84 | The DES_PTR macro option checked and used by SSLeay configuration | ||
85 | |||
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> | ||
94 | |||
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. | ||
99 | |||
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. | ||
117 | |||
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 :-) | ||
123 | |||
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. | ||
129 | |||
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 | ||
134 | |||
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. | ||
138 | |||
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. | ||
143 | |||
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. | ||
152 | |||
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 :-) | ||
157 | |||
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. | ||
168 | |||
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. | ||
173 | |||
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. | ||
183 | |||
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. | ||
190 | |||
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>. | ||
195 | |||
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. | ||
199 | |||
200 | Version 3.07 05/12/94 | ||
201 | Added GNUmake and stuff so the library can be build with | ||
202 | glibc. | ||
203 | |||
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> | ||
210 | |||
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> | ||
215 | |||
216 | Version 3.04 20/04/94 | ||
217 | Added a version number to des.c and libdes.a | ||
218 | |||
219 | Version 3.03 12/01/94 | ||
220 | Fixed a bug in non zero iv in 3cbc_enc. | ||
221 | |||
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 :-) | ||
226 | |||
227 | Release upon comp.sources.misc | ||
228 | Version 3.01 08/10/93 | ||
229 | Added des_3cbc_encrypt() | ||
230 | |||
231 | Version 3.00 07/10/93 | ||
232 | Fixed up documentation. | ||
233 | quad_cksum definitely compatible with MIT's now. | ||
234 | |||
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. | ||
240 | |||
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. | ||
244 | |||
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. | ||
250 | |||
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. | ||
256 | |||
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. | ||
260 | |||
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 :-). | ||
268 | |||
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 | ||
280 | |||
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) | ||
288 | |||
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). | ||
293 | |||
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. | ||
303 | |||
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. | ||
307 | |||
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. | ||
312 | |||
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. | ||
323 | |||
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). | ||
330 | |||
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. | ||
336 | |||
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. | ||
344 | |||
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. | ||
353 | |||
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. | ||
360 | |||
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. | ||
365 | |||
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. | ||
370 | |||
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 | ||
375 | |||
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 :-(. | ||
381 | |||
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) | ||
385 | |||
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. | ||
390 | |||
391 | Version 1.40 23/10/1990 eay | ||
