Methods

beforeClose() → List<int>
Called before close.
beforeData({required SecretKeyData secretKey, required List<int> nonce, List<int> aad = const []}) → void
Called before data is added.
convert(List<int> input, {Uint8List? possibleBuffer, Mac? expectedMac, int? chunkSize}) → Future<List<int>>
Adds input to the sequence of converted bytes and finishes converting all bytes.
override
convertChunkSync(List<int> input, {Uint8List? possibleBuffer}) → List<int>
Adds input to the sequence of converted bytes. Returns a list of converted bytes, which may be empty or larger the input.
override
convertSync(List<int> input, {Uint8List? possibleBuffer, Mac? expectedMac}) → List<int>
deriveKeySync({required SecretKeyData secretKey, required List<int> nonce}) → SecretKeyData
deriveNonce({required SecretKeyData secretKey, required List<int> nonce}) → List<int>
initialize({required bool isEncrypting, required SecretKey secretKey, required List<int> nonce, List<int> aad = const [], int keyStreamIndex = 0}) → Future<void>
Initializes the state with the given secretKey, nonce, and aad.
override
initializeSync({required bool isEncrypting, required SecretKey secretKey, required List<int> nonce, List<int> aad = const [], int keyStreamIndex = 0}) → void
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setBlock(int blockIndex) → void
Fills block with a new key stream block.
toString() → String
A string representation of this object.

Operators

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

Constants

defaultChunkSize → const int
Default chunk size for convert / convertSync.
