Simple Substitution Cipher - Practical Cryptography
Simple Substitution Cipher Introduction § The simple substitution cipher is a cipher that has been in use for many hundreds of years (an excellent history is given in Simon Singhs 'the Code Book'). It basically consists of substituting every plaintext character for a different ciphertext character.

Caesar cipher Caesar cipher, is one of the simplest and most widely known encryption techniques. The transformation can be represented by aligning two alphabets, the cipher alphabet is the plain alphabet rotated left or right by some number of positions.

Cipher - Wikipedia
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.
