WebHill Cipher is a polyalphabetic cipher created by extending the Affine cipher, using linear algebra and modular arithmetic via a numeric matrix that serves as an encryption and decryption key. How to encrypt using Hill cipher? WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it …
