WebHill cipher is one of the techniques to convert a plain text into ciphertext and vice versa. There are two parts in the Hill cipher – Encryption and Decryption. Encryption – Plain text … WebThe Hill cipher is a linear transformation of a plaintext block into a cipher block. The above attack shows that this kind of transformation is easy to break if enough pairs of plaintexts and ciphertexts are known. Modern ciphers, in fact, always contain a non-linear component to prevent this kind of attacks. Menu Home Projects Teaching
