block cipher standard
The Advanced Encryption Standard (AES) is an official block cipher standard used to encrypt data by breaking it into fixed-size blocks and scrambling them according to a mathematical algorithm. It matters because governments, businesses, and individuals rely on it to protect sensitive information like financial records and personal communications from unauthorized access.

Article
The Advanced Encryption Standard (AES), also known by its original name Rijndael ( Dutch pronunciation: [ˈrɛindaːl], RAIN-dahl), is a specification for the encryption of electronic data established by the US National Institute of Standards and Technology (NIST) in 2001.
AES is a variant of the Rijndael block cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits.
