Direct quote from the website:

"Design Automation has developed the most secure file encryption
software package available.CyberLock uses five patented encryption
enhancement technologies that make the software product very secure and
fast.

"CyberLock uses the 56-bit DES PRNG engine, then adds two further layers
of encryption enhancement, Random Coding and Random Transposition. The
result is a constantly changing, virtually impregnable defense of your
data.

"CyberLock is an application program with a very easy to use GUI
interface that runs on Windows 95 or NT. Options include three security
levels, compression, self-extraction, encrypt multiple files to a single
file and a back door option to ensure decryption if you lose the
password.

"Also offered is a set of DLL libraries that can be used by software
developers to provide encryption within their application. Our
technologies drastically improve the speed and security for all
encrypting engines including the 40-bit RC4."

Some immediate problems:
1) What, exactly, is "encryption enhancement"?
2) Since when is DES a pseudorandom number generator?
3) How do you "drastically improve speed and security" for RC4?
4) All of the eight links on the page point to the same document (the
one quoted.)

I'd steer clear of this one.
