WebDecryption involves matrix computations such as matrix inversion, and arithmetic calculations such as modular inverse. To decrypt hill ciphertext, compute the matrix inverse modulo 26 (where 26 is the alphabet length), requiring the matrix to be invertible. WebFirst, compute the determinant of the matrix, detA. If detA is coprime to p, then you can be sure that A is invertible modp. Find the inverse of detA modulo p. This matrix we denote by (detA) −1 and will be the unique integer between 0 and p which satisfie (detA) × (detA) −1 ≡ 1 mod p. Next, compute the matrix of cofactors of A, call this B.
