This repository showcases my implementation of the AES (Advanced Encryption Standard) algorithm. The AES algorithm involves key expansion, AddRoundKey, SubBytes, ShiftRows, and MixColumns stages. Additionally, I have integrated RSA encryption for secure key generation and management, I also have incorporated the Optimal Asymmetric Encryption Padding (OAEP) scheme to add an extra layer of randomness to the data before encryption.
