cryptography in Dyalog

[Stu]

I've developed a simple keyless cryptography system in Dyalog and would like to have someone who knows about cryptography take a look at it. In particular, I'd like to know (a) is the system any good, and (b) if so, does it contain original elements. There's a short paper about the system and a Dyalog workspace on my home page: www.cs.uml.edu/~stu
