This Course Focus is on Symmetric Encryption and hash functions ,we will understand the inner parts, while still making the learning curve fun and simple

We will look at secret key generation, how do we generate keys , it is much more complex than you thought

it involves permutations of the bit stream , swapping bits , shifting, substitution them and finally doing the XOR bitwise operation

You will learn the basic of modern encryption operations

We will dive into block ciphers mode of operation , how algorithms join the block ciphers together and send them along , a key concept of every symmetric encryption

And then we will learn of hash functions

hash functions are calculated to keep our messages intact .

how do we keep the integrity and authenticity of our files using salted hash and MAC's- Message Authentication Codes and hmacs , a cryptographic hash functions

I've not done much in the way of cryptography for many years because of the jobs that I've held not requiring it. I've begun exploring and revisiting some things to freshen up my experience and understanding. This was a great way to revisit with good detailed explanations in the step by step clips that were offered. Great for beginners or just an overall refresher.

This course isHands On. I will teach you the theory and the practical usage.

So come along , Cryptography is Fun
