The determinant of [ 19 7 7 4] is 19 ⋅ 4 − 7 ⋅ 7 = 1 ( mod 26), so the inverse exists and equals (using − 7 = 19 ( mod 26)) This allows us to compute the encryption matrix, and then the decryption matrix.

WebHill Cipher encrypts a group of letters called a polygraph. This method makes use of matrices from mathematics. Encryption: The key and plaintext are converted into matrix format according to the positions like a=0 to z=25. The matrices are multiplied against modulo 26. The key matrix should have an inverse to decrypt the message. C = KP mod 26.
