    Jan 13, 2009 - The RSA encryption algorithm which is commonly used in secure commerce web sites, is based on the fact that it is easy to take two (very large) prime numbers and multiply them, while it is extremely hard to do the opposite - meaning: take a very large number, given which it has only two prime factors, and find them.

    So RSA encryption works like this. I will find two huge prime numbers, p and q that have 100 or maybe 200 digits each. I will keep those two numbers secret (they are my private key), and I will multiply them together to make a number N = pq. That number N is basically my public key.
