SecretKeyData class
A SecretKey that is stored in memory.
The bytes can be accessed with bytes. The bytes can be destroyed with destroy. After calling destroy, the bytes are no longer accessible and the getter bytes will throw StateError.
Constructors
-
SecretKeyData(List<
int> bytes, {bool overwriteWhenDestroyed = false, String? debugLabel}) - Constructs a secret key with the given bytes.
- SecretKeyData.random({required int length, Uint8List? bytes, Random? random, String? debugLabel})
-
Generates N random bytes.
factory
- SecretKeyData.randomWithBuffer(Uint8List bytes, {Random? random, bool overwriteWhenDestroyed = true, String? debugLabel})
