There is definitely more to encryption than one algorithm. AFAIK, most banks are using triple DES at the moment. RSA is a popular algorithm, but there are a few problems with it (for you): 1) you must be able to pick large primes, which means you need to know fermat's little theorem as well as having some sort of large integer class, 2) you must be able to pick and encryption exponent appropriately, which is more computation. You can search for RSA online, and you'll find some reasonable explanations. DES employs left-right shifts, and an arbitrarily chosen function and key. It's tough to explain, but there are a lot of places online that have good explanations. Again, there's a problem that you need a large integer class.
