In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E woul… WebOct 19, 2024 · Cryptanalysis is the investigation of cipher content, ciphers and cryptosystems with the point of seeing how they work and finding and improving procedures for crushing or debilitating....
