The Advanced Encryption Standard (AES) is a symmetric encryption algorithm that is widely used to protect sensitive data. It was established as a standard by the National Institute of Standards and Technology (NIST) in 2001 and has since become the most widely used encryption algorithm in the world. It uses a symmetric key encryption method, which means that the same key is used to both encrypt and decrypt the data. The key length used in AES can vary, with options of 128, 192, and 256 bits.
The encryption process in AES consists of a series of substitution and permutation operations that are performed on a block of data, which is typically 128 bits. The algorithm uses a specific key to create a unique encryption of the data, making it very difficult for unauthorized parties to decipher the encrypted message without the key.
