Update on the speed issue: Part of my issue on speed is tied to the fact that my long-held private key is 2048 in length. Encrypting of the message is quite quick; decrypting is the pain in the butt. I am going to consider adding another private key of length 1024, but I will have to push that out to people for use.
All in all, however, this appears to be a fairly solid application. My only comments so far really pertain to the documentation, and you've seen those in previous messages.
