cryptography

resentely i read dan browns book "Digital Fortress", and now i am all into cryptography, even though i have always liked it. I also found a program called "Cryptix" which can do all sorts of coding, stenography, which is my favorite, where you can embed data in objects like pictures and then decode it. I need to do all my homework tommorow, and my badminton lessons for this week and next is cancelled because of tournements
