Java Cryptography Tutorial: Hashing Demo for Beginners 🔐

Hi guys we will learn in this tutorial series about the basics of cryptography and how to implement it in java.

We will start with hashing to encryption and then to encoding.

In hashing we will be using SHA-1, in ecryption we will focus on AES-128 and for encoding we will use Apache's Base64 encoder and decoder.

Here in particular, w have talked about what is hashing and how it works. This is not the same hashing has object.hashcode(). This is hashing where you implement your own model of hash using SHA-1 algo.
We see different hashing algo in theory like MD5 and SHA family and then focus on the very successful SHA-1
