- 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
