Part I is freeware shipping with the sources.
Part II (also known as DECMath) is not available as freeware and it's distribution is
only allowed for noncommercial or academical use. Please check back with the original
author regarding any commercial use. Part II is only available in the archives for
compatibility reasons. It is distributed as precompiled Delphi unit binaries
for D5, D6 and D7.

Symmetric ciphers support the following cipher modes:
CTSx = double CBC, with CFS8 padding of truncated final block
CBCx = Cipher Block Chainung, with CFB8 padding of truncated final block
CFB8 = 8bit Cipher Feedback mode
CFBx = CFB on Blocksize of Cipher
OFB8 = 8bit Output Feedback mode
OFBx = OFB on Blocksize bytes
CFS8 = 8Bit CFS, double CFB
CFSx = CFS on Blocksize bytes
ECBx = Electronic Code Book
