Explain AES Encryption algorithm.
Explanation
AES is a widely used symmetric-key block cipher that provides high security and efficiency. It encrypts data in blocks of 128 bits and uses a variable key size of 128, 192, or 256 bits. AES encryption involves four main stages: key expansion, round function, mix columns, and shift rows. AES decryption involves the inverse of these stages, making it a highly efficient and secure encryption algorithm.
