Cryptanalysis

Cryptanalysis is like a puzzle. It is when you try to figure out secret codes by looking at patterns and trying to break the code. It is like a game. People use cryptanalysis to see if they can find out if somebody is trying to keep something secret or if something is being hidden from them. Some people use cryptanalysis to try and hack into computer systems so that they can get information that is not supposed to be shared with them.
