ChaCha20ParameterSpec
public
final
class
ChaCha20ParameterSpec
extends Object
implements
AlgorithmParameterSpec
This class specifies the parameters used with the
ChaCha20
algorithm.
The parameters consist of a 12-byte nonce and an initial
counter value expressed as a 32-bit integer.
This class can be used to initialize a Cipher
object that
implements the ChaCha20 algorithm.
