WebFeb 9, 2024 · The Hill cipher, like most classical ciphers from the pre-computer era, was traditionally used to only encrypt letters: that is, the valid inputs would consist only of the 26 letters from A to Z (and, in some variants, possibly a few extra symbols to make the alphabet size a prime number).. That said, there's no reason why you couldn't use a variant of the … WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S.
