This should hopefully not affect normal + applications. + +Version 4.04 + Fixed a few tests in destest. Also added x86 assember for + des_ncbc_encrypt() which is the standard cbc mode function. + This makes a very very large performace difference. + Ariel Glenn ariel@columbia.edu reports that the terminal + 'turn echo off' can return (errno == EINVAL) under solaris + when redirection is used. So I now catch that as well as ENOTTY. + + +Version 4.03 + Left a static out of enc_write.c, which caused to buffer to be + continiously malloc()ed. Does anyone use these functions? I keep + on feeling like removing them since I only had these in there + for a version of kerberised login. Anyway, this was pointed out + by Theo de Raadt <deraadt@cvs.openbsd.org> + The 'n' bit ofb code was wrong, it was not shifting the shift + register. It worked correctly for n == 64. Thanks to + Gigi Ankeny <Gigi.Ankeny@Eng.Sun.COM> for pointing this one out. + +Version 4.02 + I was doing 'if (memcmp(weak_keys[i],key,sizeof(key)) == 0)' + when checking for weak keys which is wrong :-(, pointed out by + Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>. + +Version 4.01 + Even faster inner loop in the DES assembler for x86 and a modification + for IP/FP which is faster on x86. Both of these changes are + from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His + changes make the assembler run %40 faster on a pentium. This is just + a case of getting the instruction sequence 'just right'. + All credit to 'Svend' :-) + Quite a few special x86 'make' targets. + A libdes-l (lite) distribution. + +Version 4.00 + After a bit of a pause, I'll up the major version number since this + is mostly a performace release. I've added x86 assembler and + added more options for performance. A %28 speedup for gcc + on a pentium and the assembler is a %50 speedup. + MIPS CPU's, sparc and Alpha are the main CPU's with speedups. + Run des_opts to work out which options should be used. + DES_RISC1/DES_RISC2 use alternative inner loops which use + more registers but should give speedups on any CPU that does + dual issue (pentium). DES_UNROLL unrolls the inner loop, + which costs in code size. + +Version 3.26 + I've finally removed one of the shifts in D_ENCRYPT. This + meant I've changed the des_SPtrans table (spr.h), the set_key() + function and some things in des_enc.c. This has definitly + made things faster :-). I've known about this one for some + time but I've been too lazy to follow it up :-). + Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^.. + instead of L^=((..)|(..)|(..).. This should save a register at + least. + Assember for x86. The file to replace is des_enc.c, which is replaced + by one of the assembler files found in asm. Look at des/asm/readme + for more info. + + /* Modification to fcrypt so it can be compiled to support + HPUX 10.x's long password format, define -DLONGCRYPT to use this. + Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */ + + SIGWINCH case put in des_read_passwd() so the function does not + 'exit' if this function is recieved. + +Version 3.25 17/07/96 + Modified read_pwd.c so that stdin can be read if not a tty. + Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches. + des_init_random_number_generator() shortened due to VMS linker + limits. + Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2 + 8 byte quantites xored before and after encryption. + des_xcbc_encryption() - the name is funny to preserve the des_ + prefix on all functions. + +Version 3.24 20/04/96 + The DES_PTR macro option checked and used by SSLeay configuration + +Version 3.23 11/04/96 + Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha, + it gives a %20 speedup :-) + Fixed the problem with des.pl under perl5. The patches were + sent by Ed Kubaitis (ejk@uiuc.edu). + if fcrypt.c, changed values to handle illegal salt values the way + normal crypt() implementations do. Some programs apparently use + them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se> + +Version 3.22 29/11/95 + Bug in des(1), an error with the uuencoding stuff when the + 'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au> + for the patch. + +Version 3.21 22/11/95 + After some emailing back and forth with + Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things + and in a future version I will probably put in some of the + optimisation he suggested for use with the DES_USE_PTR option. + Extra routines from Mark Murray <mark@grondar.za> for use in + freeBSD. They mostly involve random number generation for use + with kerberos. They involve evil machine specific system calls + etc so I would normally suggest pushing this stuff into the + application and/or using RAND_seed()/RAND_bytes() if you are + using this DES library as part of SSLeay. + Redone the read_pw() function so that it is cleaner and + supports termios, thanks to Sameer Parekh <sameer@c2.org> + for the initial patches for this. + Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been + done just to make things more consistent. + I have also now added triple DES versions of cfb and ofb. + +Version 3.20 + Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com, + my des_random_seed() function was only copying 4 bytes of the + passed seed into the init structure. It is now fixed to copy 8. + My own suggestion is to used something like MD5 :-) + +Version 3.19 + While looking at my code one day, I though, why do I keep on + calling des_encrypt(in,out,ks,enc) when every function that + calls it has in and out the same. So I dropped the 'out' + parameter, people should not be using this function. + +Version 3.18 30/08/95 + Fixed a few bit with the distribution and the filenames. + 3.17 had been munged via a move to DOS and back again. + NO CODE CHANGES + +Version 3.17 14/07/95 + Fixed ede3 cbc which I had broken in 3.16. I have also + removed some unneeded variables in 7-8 of the routines. + +Version 3.16 26/06/95 + Added des_encrypt2() which does not use IP/FP, used by triple + des routines. Tweaked things a bit elsewhere. %13 speedup on + sparc and %6 on a R4400 for ede3 cbc mode. + +Version 3.15 06/06/95 + Added des_ncbc_encrypt(), it is des_cbc mode except that it is + 'normal' and copies the new iv value back over the top of the + passed parameter. + CHANGED des_ede3_cbc_encrypt() so that it too now overwrites + the iv. THIS WILL BREAK EXISTING CODE, but since this function + only new, I feel I can change it, not so with des_cbc_encrypt :-(. + I need to update the documentation. + +Version 3.14 31/05/95 + New release upon the world, as part of my SSL implementation. + New copyright and usage stuff. Basically free for all to use + as long as you say it came from me :-) + +Version 3.13 31/05/95 + A fix in speed.c, if HZ is not defined, I set it to 100.0 + which is reasonable for most unixes except SunOS 4.x. + I now have a #ifdef sun but timing for SunOS 4.x looked very + good :-(. At my last job where I used SunOS 4.x, it was + defined to be 60.0 (look at the old INSTALL documentation), at + the last release had it changed to 100.0 since I now work with + Solaris2 and SVR4 boxes. + Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this + one out. + +Version 3.12 08/05/95 + As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>, + my D_ENCRYPT macro in crypt() had an un-necessary variable. + It has been removed. + +Version 3.11 03/05/95 + Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys + and one iv. It is a standard and I needed it for my SSL code. + It makes more sense to use this for triple DES than + 3cbc_encrypt(). I have also added (or should I say tested :-) + cfb64_encrypt() which is cfb64 but it will encrypt a partial + number of bytes - 3 bytes in 3 bytes out. Again this is for + my SSL library, as a form of encryption to use with SSL + telnet. + +Version 3.10 22/03/95 + Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls + to cbc3_encrypt, the 2 iv values that were being returned to + be used in the next call were reversed :-(. + Many thanks to Bill Wade <wade@Stoner.COM> for pointing out + this error. + +Version 3.09 01/02/95 + Fixed des_random_key to far more random, it was rather feeble + with regards to picking the initial seed. The problem was + pointed out by Olaf Kirch <okir@monad.swb.de>. + +Version 3.08 14/12/94 + Added Makefile.PL so libdes can be built into perl5. + Changed des_locl.h so RAND is always defined. + +Version 3.07 05/12/94 + Added GNUmake and stuff so the library can be build with + glibc. + +Version 3.06 30/08/94 + Added rpc_enc.c which contains _des_crypt. This is for use in + secure_rpc v 4.0 + Finally fixed the cfb_enc problems. + Fixed a few parameter parsing bugs in des (-3 and -b), thanks + to Rob McMillan <R.McMillan@its.gu.edu.au> + +Version 3.05 21/04/94 + for unsigned long l; gcc does not produce ((l>>34) == 0) + This causes bugs in cfb_enc. + Thanks to Hadmut Danisch <danisch@ira.uka.de> + +Version 3.04 20/04/94 + Added a version number to des.c and libdes.a + +Version 3.03 12/01/94 + Fixed a bug in non zero iv in 3cbc_enc. + +Version 3.02 29/10/93 + I now work in a place where there are 6+ architectures and 14+ + OS versions :-). + Fixed TERMIO definition so the most sys V boxes will work :-) + +Release upon comp.sources.misc +Version 3.01 08/10/93 + Added des_3cbc_encrypt() + +Version 3.00 07/10/93 + Fixed up documentation. + quad_cksum definitely compatible with MIT's now. + +Version 2.30 24/08/93 + Triple DES now defaults to triple cbc but can do triple 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 (triple 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 avid 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 + Optimised 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 + |
