we had described in the previous article that Hill ciphers are an application of matrices to cryptography. Ciphers are methods for transforming a given message, the plaintext, into a new form that is unintelligible to anyone who does not know the key (the transformation used to convert the plaintext). In a cipher the key transforms the plaintext letters to other characters known as the ciphertext. The secret rule, that is, the inverse key, is required to reverse the transformation in order to recover the original message. To use the key to transform plaintext into ciphertext is to encipher the plaintext. To use the inverse key to transform the ciphertext back into plaintext is to decipher the ciphertext.
