Is hill cipher monoalphabetic
WebThere are various types of cipher for Encryption and Decryption such as : Caesar Cipher Monoalphabetic Cipher Homophonic Substitution Cipher Polygram Substitution Cipher Polyaphabetic Substitution Cipher Playfair Cipher Hill Cipher. In this tutorial, we will see how to encrypt and decrypt a string using the Caesar cipher in C++. WebAnswer: The basic idea of how Hill’s cipher is: * translate each letter into a number (say 0–25) * group these numbers into vectors of length n * multiply those vectors by an random, invertible nxn matrix (modulo 26), resulting in a new n-vector which is the ciphertext. Decryption proceeds by...
