1) The process in which the U.S. government (NIST) approves a cryptographic standard.
2) The winner of the latest U.S. government cryptographic testing. In this case, Rijndael won. It's a block cipher with a 128-bit block size. It uses a 128-bit, 192-bit or 256-bit key size and is considered to be extremely secure.
It's encrypted with 256-bit AES, there's no way you can crack it!
There are countless others.
