The Advanced Encryption Standard (AES) specifies a
FIPS-approved cryptographic algorithm that can be used to protect electronic
data. The AES algorithm is a symmetric block cipher that can encrypt (encipher)
and decrypt (decipher) information. Encryption converts data to an
unintelligible form called ciphertext; decrypting the ciphertext converts the
data back into its original form, called plaintext. The AES algorithm is
capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and
decrypt data in blocks of 128 bits. AES replaces the earlier DES and is
intended to be less processor-intensive to implement in software.
