By means of an easy to use OCX or VCL (for Delphi 2/3/4), just by dragging and dropping the control in your development environment, you can immediately benefit from the following encryption techniques: Block Ciphers Blowfish with up to 128 bit keys Twofish with 128, 192 and 256 bit keys DES with 64 bit (56 used) keys. Hash functions and message signing MD5 - 128 bit signature SHA1 - 160 bit signature RIPEMD160 - 160 bit signature RIPEMD128 - 128 bit signature Pseudorandom Number Generators (PRNGs) ISAAC - Period 2^2895 and 8.192 initialization bits. MT19937B - Period 2^19937 and 19.968 initialization bits. Cipher Streams Sliding XOR based on the MT19937B PRNG Encoding for transmission of binary data using 7 or less bit streams.
