WebThe Hill Cipher. The 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. Each possible pair of letters can be associated with a two-dimensional vector made from integers (mod 26) in the usual way ...
