The study of a cryptographic system for the purpose of finding weaknesses in the system and breaking the code used to encrypt the data without knowing the code��s key. There are 4 basic steps in a typical cryptanalysis: Determine the language being used Determine the system being used �� this can be a time-consuming stage […]
The art of protecting information by transforming it (encrypting it) into an unreadable format, called cipher text. Only those who possess a secret key can decipher (or decrypt) the message into plain text. Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable. As the Internet and […]
