ChaCha20ParameterSpec
class ChaCha20ParameterSpec : AlgorithmParameterSpec
| kotlin.Any | |
| ↳ | javax.crypto.spec.ChaCha20ParameterSpec |
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.
