Instead of rolling your own cryptographic algorithms, use a library. OpenSSL is pretty good, although a bit obtuse. Symmetric key ciphers are not something you want to start with as you will be very quickly overwhelmed. Start smaller with something like a MD5 hash implementation to get a feel for how "rounds", "blocks", and other odd terms in cryptography operate. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
