WebWe can express the Hill algorithm with a simple formula: C = PK mod 26. P is a vector that represents three letters from the plaintext. If the three letters are “ABC”, then the vector P= (0,1,2). K is a squared matrix that represents the key. You separate the key into three-letter blocks, and each block will be a row in the matrix K.
