Hill Cipher

Hill Cipher

Description

The Hill Cipher was developed in 1929 by Lester Hill. A digraph substitution cipher, it works using groups of letters to encrypt. However, it is different from other digraph substitution ciphers because it can work on different group sizes of letters- technically making it a polygraphic substitution cipher.

The Hill Cipher is also exceptional because it uses linear algebra, matrices, and arithmetic. This is a relatively significant amount of mathematics compared to other ciphers that can be used by hand and without a machine. For the example outlined in the images, the resulting ciphertext is: "APADJ TFTWLFJ".
