Poly1305 class abstract

Poly1305 (RFC 7539) MacAlgorithm.

If you want ChaCha20 with Poly1305 MAC, you should use ChaCha20.poly1305Aead constructor.

Things to know

  • Produces a 128 bit authentication code.
  • DO NOT use the same (key, nonce) tuple twice.
  • DO NOT use the algorithm for key derivation.
  • Poly1305 and Poly1305-AEAD (DartChacha20Poly1305AeadMacAlgorithm) are NOT the same.

Methods

calculateMac(List<int> bytes, {required SecretKey secretKey, List<int> nonce = const <int>[], List<int> aad = const <int>[]}) → Future<Mac>
Calculates message authentication code.
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<MacSink>
Constructs a sink for calculating a Mac.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
toSync() → DartPoly1305
Returns a synchronous implementation of this algorithm.

Operators

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