[464] | 27 | DESCRIPTION
|
---|
| 28 | This library provides the interfaces to the Advanced Encryption Standard (AES)
|
---|
| 29 | for encrypting and decrypting data. AES is the standard known for a symmetric
|
---|
| 30 | block cipher mechanism that uses n-bit binary string parameter key with 128-bits,
|
---|
| 31 | 192-bits, and 256-bits of key sizes.
