DESCRIPTION
|
|
This library provides the interfaces to the Advanced Encryption Standard (AES)
|
|
for encrypting and decrypting data. AES is the standard known for a symmetric
|
|
block cipher mechanism that uses n-bit binary string parameter key with 128-bits,
|
|
192-bits, and 256-bits of key sizes.
