Hill cipher 2x2 examples

This is a JavaScript implementation of the Hill Cipher. The case here is restricted to 2x2 case of the hill cipher for now, it may be expanded to 3x3 later. The 'key' should be input as 4 numbers, e.g. 3 4 19 11. These numbers will form the key (top row, bottom row). key = Ciphertext See more Invented by Lester S. Hill in 1929, the Hill cipher is a polygraphic substitution cipherbased on linear algebra. Hill used matrices and matrix … See more This example will rely on some linear algebra and some number theory.

When attempting to crack a Hill cipher, frequency analysis will be practically useless, especially as the size of the key block … See more WebWhat makes the Hill cipher a block cipher is that each plaintext string is encrypted “at once:” the change of one letter in a plaintext block is likely to change all of the letters in the ciphertext block. Notice, for example, that changing the plaintext block he to ie changes the ciphertext block from GV to JA. Decryption

The Hill Cipher encrypts blocks of letters simultaneously. For our purposes, we will assume a "block" is a pair of letters, although this encryption scheme is easily generalized to larger blocks of letters. Each possible pair of letters can be associated with a two-dimensional vector made from integers (mod 26) in the usual way ...
