Hill cipher examples
WebIn classical cryptography, the hill cipher is a polygraphic substitution cipher based on Linear Algebra. It was invented by Lester S. Hill in the year 1929. In simple words, it is a … 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
