You will learn about pseudo-randomness and how to use it for encryption. We will also look at a few basic definitions of secure encryption. Course Overview 10:34. WebThe Two-square cipher, also called double Playfair, is a manual symmetric encryption technique. [1] It was developed to ease the cumbersome nature of the large encryption/decryption matrix used in the four-square cipher while still being slightly stronger than the single-square Playfair cipher . The technique encrypts pairs of letters ...
