Advanced_Encryption_Standard

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. This is a simple implementation of Advanced Encryption Standard(AES-128) to encrypt and decrypt 16 byte of sample data using C++.

AES Procedure:

Encryption(Order)

1. Substitute Bytes
2. Shift Rows
3. Mix Columns
4. Add Round Key

Decryption(Order)

1. Shift Rows
2. Substitute Bytes
