tl;dr;
I'm assuming that be "detailing RSA encryption" you mean summarize the crytosystem;
First, research the difference between asymmetric and symmetric encryption algorithms: One involves a private/public key pairing and the other a shared private key.
Most handshakes good for setting up a secure communication involve first using the private/public to securely transfer a shared private key to both parties, and then using that shared key for encryption/decryption.
Second, figure out if RSA is symmetric or asymmetric:
http://en.wikipedia.org/wiki/RSA_(algorithm)Third, explain the algorithm for building the key(s) used by RSA. I'm being purposely vague because you are lazy and should have been able to get this far yourself.
PM me if any questions
Cheers.
