Methods

afterData() → void
inherited
beforeData({required SecretKeyData secretKey, required List<int> nonce, List<int> aad = const []}) → void
inherited
calculateMac(List<int> bytes, {required SecretKey secretKey, List<int> nonce = const <int>[], List<int> aad = const <int>[]}) → Future<Mac>
Calculates message authentication code.
inherited
calculateMacSync(List<int> bytes, {required SecretKeyData secretKeyData, required List<int> nonce, List<int> aad = const <int>[]}) → Mac
Computes a MAC synchronously (unlike calculateMac).
inherited
checkParameters({int? length, required SecretKey secretKey, required int nonceLength, required int aadLength, required int keyStreamIndex}) → void
Checks parameters and throws ArgumentError if they are invalid.
inherited
newMacSink({required SecretKey secretKey, List<int> nonce = const <int>[], List<int> aad = const <int>[]}) → Future<DartMacSinkMixin>
Constructs a sink for calculating a Mac.
inherited
newMacSinkSync({required SecretKeyData secretKeyData, List<int> nonce = const <int>[], List<int> aad = const <int>[]}) → DartMacSinkMixin
Returns DartMacSinkMixin, which can be used synchronously.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
toSync() → DartChacha20Poly1305AeadMacAlgorithm
Returns a synchronous implementation of this algorithm.

Operators

operator ==(Object other) → bool
The equality operator.
