One of the author's reasons for writing a new encryption program was to be able to generate key pairs from a pass phrase. This seems convenient but at the same time must increase risk of compromise. Unless the pass phrases are incredibly long and weird they are going to have less entropy than a long binary key pair. The rules of language and the restricted set of words might well make his encryption fairly easily breakable. Seems like a nice but very risky idea.
