Advanced Encryption Standard (AES)
Advanced Encryption Standard (AES) The Advanced Encryption Standard (AES) is a symmetric encryption algorithm established by the U.S. National Institute of Standards and Technology in 2001 (NIST). It has been since regarded as a default algorithm for protecting sensitive data and classified information. AES encrypts data in a fixed block size of 128 bits and supports […]
