information secret‚ you have two possible strategies: hide the existence of the information‚ or make the information unintelligible. Cryptography is the art and science of keeping information secure from unintended audiences‚ of encrypting it. Conversely‚ cryptanalysis is the art and science of breaking encoded data. The branch of mathematics encompassing both cryptography and cryptanalysis is cryptology. This method of secrecy has existed since 1900 B.C. in the form of Egyptian hieroglyphs. Up to

Substitution and transposition ciphers are two categories of ciphers used in classical cryptography. Substitution and transposition differ in how chunks of the message are handled by the encryption process. Substitution ciphers encrypt plaintext by changing the plaintext one piece at a time. Transposition ciphers encrypt plaintext by moving small pieces of the message around. A transposition cipher doesn’t change the characters in the plaintext when it generates the cipher text‚ it just re-arranges
