Version 3.21 22/11/95
    After some emailing back and forth with
    Colin Plumb <[e-mail]>, 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 <[e-mail]> 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 <[e-mail]>
    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 [e-mail],
    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 <[e-mail]> for pointing this
    one out.

Version 3.12 08/05/95
    As pointed out by The Crypt Keeper <[e-mail]>,
    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 <[e-mail]> 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 <[e-mail]>.

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 <[e-mail]>

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 <[e-mail]>

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 [e-mail].

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 ([e-mail])
     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 ([e-mail])
     for helping me fix the code to run on 64bit machines (he had
     access to an ETA10).
    Thanks also to John Fletcher <[e-mail]>
     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 ([e-mail])

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 <[e-mail]>, 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
     [e-mail] (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 [e-mail].
    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 <[e-mail]>
    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 [e-mail]
    Added VMS mods suggested by [e-mail].  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 ([e-mail]) 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 [e-mail]) 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 [e-mail])

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
