What is Zeta Cipher Module Overview about?

The Hill cipher is an early polygraphic substitution cipher that operates on blocks of plaintext letters using linear algebra. It uses a square matrix as the encryption key to encrypt plaintext blocks into ciphertext blocks by multiplying the block vectors. The decryption process involves multiplying the ciphertext vectors by the inverse matrix to recover the plaintext. While the Hill cipher provided some security against frequency analysis by encrypting multiple letters, matrix size and known plaintext att
