Description
In this course you will learn about cryptography and hashing in Python and Java as well. You will understand most of the private key (symmetric) and pubic key (asymmetric) cryptosystems on a step by step basis. You can learn about the theory as well as the implementation for every cryptographic algorithm - and how to crack these systems (so what are the weaknesses).
