Which algorithm was chosen as AES?

The AES encryption algorithm, also known as the Rijndael algorithm, is a type of symmetric block cipher that works with 128-bit blocks of data. It uses keys of 128, 192, or 256 bits to encrypt these blocks. After encrypting each block, it combines them to create the final encrypted message or ciphertext.

When was AES-256 created?

In January 1997, NIST decided to move forward with a proposal for developing an Advanced Encryption Standard (AES), which would be secure enough to last well into the next millennium. In December of 2001, after five years of effort, the finished standard was approved and published.

Which block cipher was formally adopted as the Advanced Encryption Standard in 2001?

In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001. This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, before the Rijndael cipher was selected as the most suitable.
