I have written an encryption program called Very Good Privacy

Trademark violation here. Probably not a good thing. Is PGP trademarked? Are you sure? And if it is, is naming something Very Good Privacy a violation? Why? Legal people, please help!

I'm not sure how an encryption product that uses encryption algorithms weaker than Pretty Good Privacy can be described as being better than PGP.

Especially when all the algorithms listed have known problems of one kind, or another. << And yes, I know that the known problems -- in some instances --- are entirely theoretical in nature. >> In your quote, you deleted the smiley about VGP. It's a joke. Your claim that VGP is weaker than PGP is unfounded, as VGP uses IDEA, which is the symmetric algorithm used in PGP. ASCII and Vigenere are very weak, but they are fast and geared toward people who simply want to stop their brother or sister from getting into something. As for the security of other algorithms, BlowFish is used in PGPfone and RC4 is used in SSL -- since you control the key size in VGP, you can make RC4 virtually unbreakable (not to mention the problem of the attacker figuring out the key size in the first place).
