Version 3.24 20/04/95
Version 3.25 17/07/96
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 11/04/95
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

This is RSA's DESX mode of DES. It uses inw and outw to
'whiten' the encryption. inw and outw are secret (unlike the iv)
and are as such, part of the key. So the key is sort of 24 bytes.
This is much better than cbc des.
