WebHill Ciphers Hill ciphers (invented in 1929) are a type of block cipher: the ciphertext character that replaces a particular plaintext character in the encryption will depend on the neighboring plaintext characters. The encryption is accomplished using matrix arithmetic. The encryption key for a Hill cipher is a square matrix of integers.
