comment What are the weaknesses of this message exchange protocol?
thought my question was pretty clear,i.e.,"Why not use this secure symmetric key exchange?" An answer would be because such and such. I don't have any problems I need answers for. I think it's a good protocol and wonder why we needed DIFFIE-HELLMAN and PGP. Any good commutative, complex cipher with rounds, not simple XORing, would work. Authenticate with certificates, signing, salting of the plain text, etc.

All I'm saying is this seems a simpler key exchange than PGP etc. All that's needed is that both parties use the same crypto program and agree on an authenticator. I confess to being a hobbiest. If anyone wants the WINDOWS C# .NET program and or the source code they may have it/them.
