| 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 | |
| 392 Fixed des_random_key, it did not produce a random key :-( | |
| 393 | |
| 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 | |
