The Advanced Encryption Standard (AES) includes a 256-bit key; the previous Data Encryption Standard (DES), which the government adopted in 1977, used a 56-bit key and was surpassed by the 128-bit encryption adopted in the private sector in the early 1990s.

The implementation of EFS in Windows XP can use either the expanded Data Encryption Standard (DESX) or Triple-DES (3DES) as the encryption algorithm.

Most of the cryptographic algorithms used today are based on the Data Encryption Standard (DES) a standard developed by IBM and adopted by the US government's National Institute for Standards & Technology (NIST) for protecting sensitive information in 1977.

AES is the successor of the Data Encryption Standard (DES), developed by IBM, which is considered obsolete today.

One bright spot in the battle against wireless hackers is the recent adoption of the Rijndael data encryption formula, which will replace the old data encryption standard (DES) that was developed in 1977.
