Re: Terrorists rolling their own crypt

Also, that may confuse cryptography with cryptographic systems. Rolling your own cryptography nearly guarantees that you will make a stupid mistake and your crypto will be broken a lot faster than you thought. Using someone else's crypto that is proven to work but changing the container format and/or transmission protocol means that the people attempting to read your communications will have to pick both of those apart before they can start to crack the key. It prevents them from having a pre-built module for it that they can set going, and you're still using a proven algorithm.
