• Hill Cipher is a cryptographic algorithm to encrypt and decrypt an alphabetic text. In this cipher, each letter is represented by a number (eg. A = 0, B = 1, C = 2). To encrypt a message, each block of n letters (considered as an n -component vector) is multiplied by an invertible n × n matrix, against modulus 26.

The BAUDOT code is made from a cipher. The cipher that does this is also known as a Bacon cipher.
