Software Security — How does AES (Advanced Encryption Standard) work

Explained step by step with example

Definition

Advanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. AES is widely used today as it is a much stronger than DES and triple DES despite being harder to implement.

How it works

AES encryption is split into 5 processes, and each process will run 10 rounds.
