WebThe Hill Cipher encrypts blocks of letters simultaneously. For our purposes, we will assume a "block" is a pair of letters, although this encryption scheme is easily generalized to larger blocks of letters. WebThe cipher is polyalphabetic, which means that a character can be enciphered in different ways—for example, an "A" in one subtext could be encoded as a "T", and in another subtext it could be encoded as a "P".
