Description
In this module, we are going to do a lot of hands-on work to learn how to implement all the famous techniques and methodologies of Cryptography practically. We will cover most of the private key cryptosystems such as Caesar cipher, Vigenère cipher, Data Encryption Standard (DES) and Advanced Encryption Standard (AES). At the end of the module, the participant will be able to understand cryptography more widely.
