+ Fixed the weak key values which were wrong :-(
+ Defining SIGACTION causes sigaction() to be used instead of signal().
+ SIGUSR1/SIGUSR2 are no longer mapped in the read tty stuff because it
+ can cause problems. 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
