1*60662d10Schristos Fixed the weak key values which were wrong :-( 2*60662d10Schristos Defining SIGACTION causes sigaction() to be used instead of signal(). 3*60662d10Schristos SIGUSR1/SIGUSR2 are no longer mapped in the read tty stuff because it 4*60662d10Schristos can cause problems. This should hopefully not affect normal 5*60662d10Schristos applications. 6*60662d10Schristos 7*60662d10SchristosVersion 4.04 8*60662d10Schristos Fixed a few tests in destest. Also added x86 assember for 9*60662d10Schristos des_ncbc_encrypt() which is the standard cbc mode function. 10*60662d10Schristos This makes a very very large performace difference. 11*60662d10Schristos Ariel Glenn ariel@columbia.edu reports that the terminal 12*60662d10Schristos 'turn echo off' can return (errno == EINVAL) under solaris 13*60662d10Schristos when redirection is used. So I now catch that as well as ENOTTY. 14*60662d10Schristos 15*60662d10Schristos 16*60662d10SchristosVersion 4.03 17*60662d10Schristos Left a static out of enc_write.c, which caused to buffer to be 18*60662d10Schristos continiously malloc()ed. Does anyone use these functions? I keep 19*60662d10Schristos on feeling like removing them since I only had these in there 20*60662d10Schristos for a version of kerberised login. Anyway, this was pointed out 21*60662d10Schristos by Theo de Raadt <deraadt@cvs.openbsd.org> 22*60662d10Schristos The 'n' bit ofb code was wrong, it was not shifting the shift 23*60662d10Schristos register. It worked correctly for n == 64. Thanks to 24*60662d10Schristos Gigi Ankeny <Gigi.Ankeny@Eng.Sun.COM> for pointing this one out. 25*60662d10Schristos 26*60662d10SchristosVersion 4.02 27*60662d10Schristos I was doing 'if (memcmp(weak_keys[i],key,sizeof(key)) == 0)' 28*60662d10Schristos when checking for weak keys which is wrong :-(, pointed out by 29*60662d10Schristos Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>. 30*60662d10Schristos 31*60662d10SchristosVersion 4.01 32*60662d10Schristos Even faster inner loop in the DES assembler for x86 and a modification 33*60662d10Schristos for IP/FP which is faster on x86. Both of these changes are 34*60662d10Schristos from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His 35*60662d10Schristos changes make the assembler run %40 faster on a pentium. This is just 36*60662d10Schristos a case of getting the instruction sequence 'just right'. 37*60662d10Schristos All credit to 'Svend' :-) 38*60662d10Schristos Quite a few special x86 'make' targets. 39*60662d10Schristos A libdes-l (lite) distribution. 40*60662d10Schristos 41*60662d10SchristosVersion 4.00 42*60662d10Schristos After a bit of a pause, I'll up the major version number since this 43*60662d10Schristos is mostly a performace release. I've added x86 assembler and 44*60662d10Schristos added more options for performance. A %28 speedup for gcc 45*60662d10Schristos on a pentium and the assembler is a %50 speedup. 46*60662d10Schristos MIPS CPU's, sparc and Alpha are the main CPU's with speedups. 47*60662d10Schristos Run des_opts to work out which options should be used. 48*60662d10Schristos DES_RISC1/DES_RISC2 use alternative inner loops which use 49*60662d10Schristos more registers but should give speedups on any CPU that does 50*60662d10Schristos dual issue (pentium). DES_UNROLL unrolls the inner loop, 51*60662d10Schristos which costs in code size. 52*60662d10Schristos 53*60662d10SchristosVersion 3.26 54*60662d10Schristos I've finally removed one of the shifts in D_ENCRYPT. This 55*60662d10Schristos meant I've changed the des_SPtrans table (spr.h), the set_key() 56*60662d10Schristos function and some things in des_enc.c. This has definitly 57*60662d10Schristos made things faster :-). I've known about this one for some 58*60662d10Schristos time but I've been too lazy to follow it up :-). 59*60662d10Schristos Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^.. 60*60662d10Schristos instead of L^=((..)|(..)|(..).. This should save a register at 61*60662d10Schristos least. 62*60662d10Schristos Assember for x86. The file to replace is des_enc.c, which is replaced 63*60662d10Schristos by one of the assembler files found in asm. Look at des/asm/readme 64*60662d10Schristos for more info. 65*60662d10Schristos 66*60662d10Schristos /* Modification to fcrypt so it can be compiled to support 67*60662d10Schristos HPUX 10.x's long password format, define -DLONGCRYPT to use this. 68*60662d10Schristos Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */ 69*60662d10Schristos 70*60662d10Schristos SIGWINCH case put in des_read_passwd() so the function does not 71*60662d10Schristos 'exit' if this function is recieved. 72*60662d10Schristos 73*60662d10SchristosVersion 3.25 17/07/96 74*60662d10Schristos Modified read_pwd.c so that stdin can be read if not a tty. 75*60662d10Schristos Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches. 76*60662d10Schristos des_init_random_number_generator() shortened due to VMS linker 77*60662d10Schristos limits. 78*60662d10Schristos Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2 79*60662d10Schristos 8 byte quantites xored before and after encryption. 80*60662d10Schristos des_xcbc_encryption() - the name is funny to preserve the des_ 81*60662d10Schristos prefix on all functions. 82*60662d10Schristos 83*60662d10SchristosVersion 3.24 20/04/96 84*60662d10Schristos The DES_PTR macro option checked and used by SSLeay configuration 85*60662d10Schristos 86*60662d10SchristosVersion 3.23 11/04/96 87*60662d10Schristos Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha, 88*60662d10Schristos it gives a %20 speedup :-) 89*60662d10Schristos Fixed the problem with des.pl under perl5. The patches were 90*60662d10Schristos sent by Ed Kubaitis (ejk@uiuc.edu). 91*60662d10Schristos if fcrypt.c, changed values to handle illegal salt values the way 92*60662d10Schristos normal crypt() implementations do. Some programs apparently use 93*60662d10Schristos them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se> 94*60662d10Schristos 95*60662d10SchristosVersion 3.22 29/11/95 96*60662d10Schristos Bug in des(1), an error with the uuencoding stuff when the 97*60662d10Schristos 'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au> 98*60662d10Schristos for the patch. 99*60662d10Schristos 100*60662d10SchristosVersion 3.21 22/11/95 101*60662d10Schristos After some emailing back and forth with 102*60662d10Schristos Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things 103*60662d10Schristos and in a future version I will probably put in some of the 104*60662d10Schristos optimisation he suggested for use with the DES_USE_PTR option. 105*60662d10Schristos Extra routines from Mark Murray <mark@grondar.za> for use in 106*60662d10Schristos freeBSD. They mostly involve random number generation for use 107*60662d10Schristos with kerberos. They involve evil machine specific system calls 108*60662d10Schristos etc so I would normally suggest pushing this stuff into the 109*60662d10Schristos application and/or using RAND_seed()/RAND_bytes() if you are 110*60662d10Schristos using this DES library as part of SSLeay. 111*60662d10Schristos Redone the read_pw() function so that it is cleaner and 112*60662d10Schristos supports termios, thanks to Sameer Parekh <sameer@c2.org> 113*60662d10Schristos for the initial patches for this. 114*60662d10Schristos Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been 115*60662d10Schristos done just to make things more consistent. 116*60662d10Schristos I have also now added triple DES versions of cfb and ofb. 117*60662d10Schristos 118*60662d10SchristosVersion 3.20 119*60662d10Schristos Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com, 120*60662d10Schristos my des_random_seed() function was only copying 4 bytes of the 121*60662d10Schristos passed seed into the init structure. It is now fixed to copy 8. 122*60662d10Schristos My own suggestion is to used something like MD5 :-) 123*60662d10Schristos 124*60662d10SchristosVersion 3.19 125*60662d10Schristos While looking at my code one day, I though, why do I keep on 126*60662d10Schristos calling des_encrypt(in,out,ks,enc) when every function that 127*60662d10Schristos calls it has in and out the same. So I dropped the 'out' 128*60662d10Schristos parameter, people should not be using this function. 129*60662d10Schristos 130*60662d10SchristosVersion 3.18 30/08/95 131*60662d10Schristos Fixed a few bit with the distribution and the filenames. 132*60662d10Schristos 3.17 had been munged via a move to DOS and back again. 133*60662d10Schristos NO CODE CHANGES 134*60662d10Schristos 135*60662d10SchristosVersion 3.17 14/07/95 136*60662d10Schristos Fixed ede3 cbc which I had broken in 3.16. I have also 137*60662d10Schristos removed some unneeded variables in 7-8 of the routines. 138*60662d10Schristos 139*60662d10SchristosVersion 3.16 26/06/95 140*60662d10Schristos Added des_encrypt2() which does not use IP/FP, used by triple 141*60662d10Schristos des routines. Tweaked things a bit elsewhere. %13 speedup on 142*60662d10Schristos sparc and %6 on a R4400 for ede3 cbc mode. 143*60662d10Schristos 144*60662d10SchristosVersion 3.15 06/06/95 145*60662d10Schristos Added des_ncbc_encrypt(), it is des_cbc mode except that it is 146*60662d10Schristos 'normal' and copies the new iv value back over the top of the 147*60662d10Schristos passed parameter. 148*60662d10Schristos CHANGED des_ede3_cbc_encrypt() so that it too now overwrites 149*60662d10Schristos the iv. THIS WILL BREAK EXISTING CODE, but since this function 150*60662d10Schristos only new, I feel I can change it, not so with des_cbc_encrypt :-(. 151*60662d10Schristos I need to update the documentation. 152*60662d10Schristos 153*60662d10SchristosVersion 3.14 31/05/95 154*60662d10Schristos New release upon the world, as part of my SSL implementation. 155*60662d10Schristos New copyright and usage stuff. Basically free for all to use 156*60662d10Schristos as long as you say it came from me :-) 157*60662d10Schristos 158*60662d10SchristosVersion 3.13 31/05/95 159*60662d10Schristos A fix in speed.c, if HZ is not defined, I set it to 100.0 160*60662d10Schristos which is reasonable for most unixes except SunOS 4.x. 161*60662d10Schristos I now have a #ifdef sun but timing for SunOS 4.x looked very 162*60662d10Schristos good :-(. At my last job where I used SunOS 4.x, it was 163*60662d10Schristos defined to be 60.0 (look at the old INSTALL documentation), at 164*60662d10Schristos the last release had it changed to 100.0 since I now work with 165*60662d10Schristos Solaris2 and SVR4 boxes. 166*60662d10Schristos Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this 167*60662d10Schristos one out. 168*60662d10Schristos 169*60662d10SchristosVersion 3.12 08/05/95 170*60662d10Schristos As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>, 171*60662d10Schristos my D_ENCRYPT macro in crypt() had an un-necessary variable. 172*60662d10Schristos It has been removed. 173*60662d10Schristos 174*60662d10SchristosVersion 3.11 03/05/95 175*60662d10Schristos Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys 176*60662d10Schristos and one iv. It is a standard and I needed it for my SSL code. 177*60662d10Schristos It makes more sense to use this for triple DES than 178*60662d10Schristos 3cbc_encrypt(). I have also added (or should I say tested :-) 179*60662d10Schristos cfb64_encrypt() which is cfb64 but it will encrypt a partial 180*60662d10Schristos number of bytes - 3 bytes in 3 bytes out. Again this is for 181*60662d10Schristos my SSL library, as a form of encryption to use with SSL 182*60662d10Schristos telnet. 183*60662d10Schristos 184*60662d10SchristosVersion 3.10 22/03/95 185*60662d10Schristos Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls 186*60662d10Schristos to cbc3_encrypt, the 2 iv values that were being returned to 187*60662d10Schristos be used in the next call were reversed :-(. 188*60662d10Schristos Many thanks to Bill Wade <wade@Stoner.COM> for pointing out 189*60662d10Schristos this error. 190*60662d10Schristos 191*60662d10SchristosVersion 3.09 01/02/95 192*60662d10Schristos Fixed des_random_key to far more random, it was rather feeble 193*60662d10Schristos with regards to picking the initial seed. The problem was 194*60662d10Schristos pointed out by Olaf Kirch <okir@monad.swb.de>. 195*60662d10Schristos 196*60662d10SchristosVersion 3.08 14/12/94 197*60662d10Schristos Added Makefile.PL so libdes can be built into perl5. 198*60662d10Schristos Changed des_locl.h so RAND is always defined. 199*60662d10Schristos 200*60662d10SchristosVersion 3.07 05/12/94 201*60662d10Schristos Added GNUmake and stuff so the library can be build with 202*60662d10Schristos glibc. 203*60662d10Schristos 204*60662d10SchristosVersion 3.06 30/08/94 205*60662d10Schristos Added rpc_enc.c which contains _des_crypt. This is for use in 206*60662d10Schristos secure_rpc v 4.0 207*60662d10Schristos Finally fixed the cfb_enc problems. 208*60662d10Schristos Fixed a few parameter parsing bugs in des (-3 and -b), thanks 209*60662d10Schristos to Rob McMillan <R.McMillan@its.gu.edu.au> 210*60662d10Schristos 211*60662d10SchristosVersion 3.05 21/04/94 212*60662d10Schristos for unsigned long l; gcc does not produce ((l>>34) == 0) 213*60662d10Schristos This causes bugs in cfb_enc. 214*60662d10Schristos Thanks to Hadmut Danisch <danisch@ira.uka.de> 215*60662d10Schristos 216*60662d10SchristosVersion 3.04 20/04/94 217*60662d10Schristos Added a version number to des.c and libdes.a 218*60662d10Schristos 219*60662d10SchristosVersion 3.03 12/01/94 220*60662d10Schristos Fixed a bug in non zero iv in 3cbc_enc. 221*60662d10Schristos 222*60662d10SchristosVersion 3.02 29/10/93 223*60662d10Schristos I now work in a place where there are 6+ architectures and 14+ 224*60662d10Schristos OS versions :-). 225*60662d10Schristos Fixed TERMIO definition so the most sys V boxes will work :-) 226*60662d10Schristos 227*60662d10SchristosRelease upon comp.sources.misc 228*60662d10SchristosVersion 3.01 08/10/93 229*60662d10Schristos Added des_3cbc_encrypt() 230*60662d10Schristos 231*60662d10SchristosVersion 3.00 07/10/93 232*60662d10Schristos Fixed up documentation. 233*60662d10Schristos quad_cksum definitely compatible with MIT's now. 234*60662d10Schristos 235*60662d10SchristosVersion 2.30 24/08/93 236*60662d10Schristos Triple DES now defaults to triple cbc but can do triple ecb 237*60662d10Schristos with the -b flag. 238*60662d10Schristos Fixed some MSDOS uuen/uudecoding problems, thanks to 239*60662d10Schristos Added prototypes. 240*60662d10Schristos 241*60662d10SchristosVersion 2.22 29/06/93 242*60662d10Schristos Fixed a bug in des_is_weak_key() which stopped it working :-( 243*60662d10Schristos thanks to engineering@MorningStar.Com. 244*60662d10Schristos 245*60662d10SchristosVersion 2.21 03/06/93 246*60662d10Schristos des(1) with no arguments gives quite a bit of help. 247*60662d10Schristos Added -c (generate ckecksum) flag to des(1). 248*60662d10Schristos Added -3 (triple DES) flag to des(1). 249*60662d10Schristos Added cfb and ofb routines to the library. 250*60662d10Schristos 251*60662d10SchristosVersion 2.20 11/03/93 252*60662d10Schristos Added -u (uuencode) flag to des(1). 253*60662d10Schristos I have been playing with byte order in quad_cksum to make it 254*60662d10Schristos compatible with MIT's version. All I can say is avid this 255*60662d10Schristos function if possible since MIT's output is endian dependent. 256*60662d10Schristos 257*60662d10SchristosVersion 2.12 14/10/92 258*60662d10Schristos Added MSDOS specific macro in ecb_encrypt which gives a %70 259*60662d10Schristos speed up when the code is compiled with turbo C. 260*60662d10Schristos 261*60662d10SchristosVersion 2.11 12/10/92 262*60662d10Schristos Speedup in set_key (recoding of PC-1) 263*60662d10Schristos I now do it in 47 simple operations, down from 60. 264*60662d10Schristos Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov) 265*60662d10Schristos for motivating me to look for a faster system :-) 266*60662d10Schristos The speedup is probably less that 1% but it is still 13 267*60662d10Schristos instructions less :-). 268*60662d10Schristos 269*60662d10SchristosVersion 2.10 06/10/92 270*60662d10Schristos The code now works on the 64bit ETA10 and CRAY without modifications or 271*60662d10Schristos #defines. I believe the code should work on any machine that 272*60662d10Schristos defines long, int or short to be 8 bytes long. 273*60662d10Schristos Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu) 274*60662d10Schristos for helping me fix the code to run on 64bit machines (he had 275*60662d10Schristos access to an ETA10). 276*60662d10Schristos Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov> 277*60662d10Schristos for testing the routines on a CRAY. 278*60662d10Schristos read_password.c has been renamed to read_passwd.c 279*60662d10Schristos string_to_key.c has been renamed to string2key.c 280*60662d10Schristos 281*60662d10SchristosVersion 2.00 14/09/92 282*60662d10Schristos Made mods so that the library should work on 64bit CPU's. 283*60662d10Schristos Removed all my uchar and ulong defs. To many different 284*60662d10Schristos versions of unix define them in their header files in too many 285*60662d10Schristos different combinations :-) 286*60662d10Schristos IRIX - Sillicon Graphics mods (mostly in read_password.c). 287*60662d10Schristos Thanks to Andrew Daviel (advax@erich.triumf.ca) 288*60662d10Schristos 289*60662d10SchristosVersion 1.99 26/08/92 290*60662d10Schristos Fixed a bug or 2 in enc_read.c 291*60662d10Schristos Fixed a bug in enc_write.c 292*60662d10Schristos Fixed a pseudo bug in fcrypt.c (very obscure). 293*60662d10Schristos 294*60662d10SchristosVersion 1.98 31/07/92 295*60662d10Schristos Support for the ETA10. This is a strange machine that defines 296*60662d10Schristos longs and ints as 8 bytes and shorts as 4 bytes. 297*60662d10Schristos Since I do evil things with long * that assume that they are 4 298*60662d10Schristos bytes. Look in the Makefile for the option to compile for 299*60662d10Schristos this machine. quad_cksum appears to have problems but I 300*60662d10Schristos will don't have the time to fix it right now, and this is not 301*60662d10Schristos a function that uses DES and so will not effect the main uses 302*60662d10Schristos of the library. 303*60662d10Schristos 304*60662d10SchristosVersion 1.97 20/05/92 eay 305*60662d10Schristos Fixed the Imakefile and made some changes to des.h to fix some 306*60662d10Schristos problems when building this package with Kerberos v 4. 307*60662d10Schristos 308*60662d10SchristosVersion 1.96 18/05/92 eay 309*60662d10Schristos Fixed a small bug in string_to_key() where problems could 310*60662d10Schristos occur if des_check_key was set to true and the string 311*60662d10Schristos generated a weak key. 312*60662d10Schristos 313*60662d10SchristosPatch2 posted to comp.sources.misc 314*60662d10SchristosVersion 1.95 13/05/92 eay 315*60662d10Schristos Added an alternative version of the D_ENCRYPT macro in 316*60662d10Schristos ecb_encrypt and fcrypt. Depending on the compiler, one version or the 317*60662d10Schristos other will be faster. This was inspired by 318*60662d10Schristos Dana How <how@isl.stanford.edu>, and her pointers about doing the 319*60662d10Schristos *(ulong *)((uchar *)ptr+(value&0xfc)) 320*60662d10Schristos vs 321*60662d10Schristos ptr[value&0x3f] 322*60662d10Schristos to stop the C compiler doing a <<2 to convert the long array index. 323*60662d10Schristos 324*60662d10SchristosVersion 1.94 05/05/92 eay 325*60662d10Schristos Fixed an incompatibility between my string_to_key and the MIT 326*60662d10Schristos version. When the key is longer than 8 chars, I was wrapping 327*60662d10Schristos with a different method. To use the old version, define 328*60662d10Schristos OLD_STR_TO_KEY in the makefile. Thanks to 329*60662d10Schristos viktor@newsu.shearson.com (Viktor Dukhovni). 330*60662d10Schristos 331*60662d10SchristosVersion 1.93 28/04/92 eay 332*60662d10Schristos Fixed the VMS mods so that echo is now turned off in 333*60662d10Schristos read_password. Thanks again to brennan@coco.cchs.su.oz.AU. 334*60662d10Schristos MSDOS support added. The routines can be compiled with 335*60662d10Schristos Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined. 336*60662d10Schristos 337*60662d10SchristosPatch1 posted to comp.sources.misc 338*60662d10SchristosVersion 1.92 13/04/92 eay 339*60662d10Schristos Changed D_ENCRYPT so that the rotation of R occurs outside of 340*60662d10Schristos the loop. This required rotating all the longs in sp.h (now 341*60662d10Schristos called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM> 342*60662d10Schristos speed.c has been changed so it will work without SIGALRM. If 343*60662d10Schristos times(3) is not present it will try to use ftime() instead. 344*60662d10Schristos 345*60662d10SchristosVersion 1.91 08/04/92 eay 346*60662d10Schristos Added -E/-D options to des(1) so it can use string_to_key. 347*60662d10Schristos Added SVR4 mods suggested by witr@rwwa.COM 348*60662d10Schristos Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If 349*60662d10Schristos anyone knows how to turn of tty echo in VMS please tell me or 350*60662d10Schristos implement it yourself :-). 351*60662d10Schristos Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS 352*60662d10Schristos does not like IN/OUT being used. 353*60662d10Schristos 354*60662d10SchristosLibdes posted to comp.sources.misc 355*60662d10SchristosVersion 1.9 24/03/92 eay 356*60662d10Schristos Now contains a fast small crypt replacement. 357*60662d10Schristos Added des(1) command. 358*60662d10Schristos Added des_rw_mode so people can use cbc encryption with 359*60662d10Schristos enc_read and enc_write. 360*60662d10Schristos 361*60662d10SchristosVersion 1.8 15/10/91 eay 362*60662d10Schristos Bug in cbc_cksum. 363*60662d10Schristos Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this 364*60662d10Schristos one out. 365*60662d10Schristos 366*60662d10SchristosVersion 1.7 24/09/91 eay 367*60662d10Schristos Fixed set_key :-) 368*60662d10Schristos set_key is 4 times faster and takes less space. 369*60662d10Schristos There are a few minor changes that could be made. 370*60662d10Schristos 371*60662d10SchristosVersion 1.6 19/09/1991 eay 372*60662d10Schristos Finally go IP and FP finished. 373*60662d10Schristos Now I need to fix set_key. 374*60662d10Schristos This version is quite a bit faster that 1.51 375*60662d10Schristos 376*60662d10SchristosVersion 1.52 15/06/1991 eay 377*60662d10Schristos 20% speedup in ecb_encrypt by changing the E bit selection 378*60662d10Schristos to use 2 32bit words. This also required modification of the 379*60662d10Schristos sp table. There is still a way to speedup the IP and IP-1 380*60662d10Schristos (hints from outer@sq.com) still working on this one :-(. 381*60662d10Schristos 382*60662d10SchristosVersion 1.51 07/06/1991 eay 383*60662d10Schristos Faster des_encrypt by loop unrolling 384*60662d10Schristos Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu) 385*60662d10Schristos 386*60662d10SchristosVersion 1.50 28/05/1991 eay 387*60662d10Schristos Optimised the code a bit more for the sparc. I have improved the 388*60662d10Schristos speed of the inner des_encrypt by speeding up the initial and 389*60662d10Schristos final permutations. 390*60662d10Schristos 391*60662d10SchristosVersion 1.40 23/10/1990 eay 392*60662d10Schristos Fixed des_random_key, it did not produce a random key :-( 393*60662d10Schristos 394*60662d10SchristosVersion 1.30 2/10/1990 eay 395*60662d10Schristos Have made des_quad_cksum the same as MIT's, the full package 396*60662d10Schristos should be compatible with MIT's 397*60662d10Schristos Have tested on a DECstation 3100 398*60662d10Schristos Still need to fix des_set_key (make it faster). 399*60662d10Schristos Does des_cbc_encrypts at 70.5k/sec on a 3100. 400*60662d10Schristos 401*60662d10SchristosVersion 1.20 18/09/1990 eay 402*60662d10Schristos Fixed byte order dependencies. 403*60662d10Schristos Fixed (I hope) all the word alignment problems. 404*60662d10Schristos Speedup in des_ecb_encrypt. 405*60662d10Schristos 406*60662d10SchristosVersion 1.10 11/09/1990 eay 407*60662d10Schristos Added des_enc_read and des_enc_write. 408*60662d10Schristos Still need to fix des_quad_cksum. 409*60662d10Schristos Still need to document des_enc_read and des_enc_write. 410*60662d10Schristos 411*60662d10SchristosVersion 1.00 27/08/1990 eay 412*60662d10Schristos 413
