Classical Ciphers Hill Cipher Encryption Decryption Using Extended Euclidean Algorithm - Detailed Analysis
In this lecture we are going to understand how to n matrix chosen. Each block of plaintext letters is then converted into a vector of numbers and is dotted Decryption of ciphertext using modular inverse of a matrix (example 2) They key will be a square matrix for which we will find the inverse. In this video I walk through the basics of the
