A great read for people wandering about how this crypto realy works !!
Read the entire articleUsing OpenSSL to explore some of the details of how RSA encryption works.
When sending your credit card number through a public medium, such as the Internet, your financial credibility may be compromised if the number is not first encrypted. It is impossible to tell who may be listening in on your connection as you shop for new CDs or books. The RSA encryption method often is used to hide your credit card number from would-be thiefs on the Internet, because it uses a public key to hide your information and a private key to reveal it. This article banishes the mystery surrounding RSA encryption and explains how a realistic implementation of RSA works in the OpenSSL library.
If after reading this article you wanna do some math of your own..
try it.. and perhaps win them 'big bucks'
