comment Cryptography system by combining a block cipher and a stream cipher
Come on, guy. You said this was for an assignment. Maybe do some part of it yourself? :-)

Shrug I thought so as well, but hopefully my answer can be somewhat helpful either way.

comment How do decryption algorithms determine whether your attempted passphrase is correct?
An HMAC is a hash value (such as a SHA1 hash) that is generated by evaluating the plaintext in conjunction with an authentication key. The authentication key is necessary to prevent the modification of the HMAC itself. During verification, the same HMAC procedure is performed on the plaintext to be verified using the same authentication key. If the same final HMAC is obtained, we know we have the plaintext we're looking for.

comment Is it safer to generate your own Diffie-Hellman primes or to use those defined in RFC 3526?
Thank you! I was wondering - are the primes defined in the RFC special in any other way than being derived from Pi? Have they undergone any other testing? If so, what makes them safer or better studied?
