AES is a symmetric encryption algorithm standardized by the National Institute of Standards and Technology (NIST). It operates on fixed block sizes of 128 bits and employs a 128-bit key to encrypt and decrypt data securely. AES is widely used for securing sensitive data due to its strong encryption, efficiency, and resistance to most known attacks
