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. WebDigraph frequency analysis of text encrypted by a Hill 2-cipher suggests that the cipher-text digraphs ( ) (use the first two letters of your first name, for example I would use (CI)) and ( ) (use the first two letters of your last name, for example I would use (MA)) correspond to the plaintext digraphs (TH) and (HE) in that order.
