Webmatrix is used to encrypt the messages, and its inverse is used to decrypt the encoded messages. It is important that the key matrix be kept secret between the message … Each letter is represented by a number modulo 26. Though this is not an essential feature of the cipher, this simple scheme is often used: To encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption.
