Well, then an answer about how to implement the protocol safely disregarding the legal aspect would be welcome.

comment Security of Pohlig-Hellman exponentation cipher?
The application is mental poker. I asked about the security in a separate question - crypto.stackexchange.com/q/6575/843 .

@HenrickHellström - I asked about it in a separate question - crypto.stackexchange.com/q/6575/843 .

@CodesInChaos The application is mental poker - the messages are very short.

Actually, here is the question about the same thing - crypto.stackexchange.com/a/1366/843 .

comment Security of Pohlig-Hellman exponentation cipher?
I need a commutative cipher for an application where two or more peers need to encrypt and decrypt data out of order. I can only find information on two algorithms, with this being the better one apparently. I guess I should ask about commutative ciphers in a separate question...

comment Hashing passwords with a salt - why use different salt for everyone?
@starblue Yes, but a single salt plus unique username would prevent the attacker from amortising their effort as they would not be able to look for more than one user's password at a time.

@StephenTouset I am not implementing such a system myself, I'm just curious about the problem. This question is just to satisfy that curiosity.
