WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once. The following discussion assumes an elementary knowledge of matrices. Each letter is first encoded as … WebThe working is shown below: Input : 1.Plain text that has to be converted into ciphertext. 2.A KEY to encrypt the plain text. Output: Ciphertext. We have a simple formula for encryption. C = KPmod26. C is ciphertext, K is the key, P is the plain text vector. The KEY is generally given in the problem statement.
