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 cryptography algorithm used to encrypt and decrypt data for the purpose of data security. The algorithm uses matrix calculations used in Linear Algebra. northeast retina associatesWeb2x2 Hill Cipher in Python00:06 - Importing libraries00:12 - Encryption Function00:59 - Message to 2x"message length / 2" matrix02:30 - Key to 2x2 matrix 03:1... northeast retinaWebInvented by Lester S.
