Poly1305Sink class

This implementation is derived from the The Poly1305 Algorithms described in the ChaCha20 and Poly1305 for IETF Protocols document.

Constructors

Poly1305Sink.new(Uint8List key): Creates a new instance to process 16-bytes blocks with 17-bytes buffer

bdata → ByteData: The buffer as ByteData
latefinalinherited
blockLength → int: The internal block length of the algorithm in bytes
finalinherited
buffer → Uint8List: The main buffer
finalinherited
closed → bool: Returns true if the sink is closed, false otherwise
no setterinherited
derivedKeyLength → int: The length of generated key in bytes
final
hashCode → int: The hash code for this object.
no setterinherited
hashLength → int: The length of generated hash in bytes
final
messageLength ↔ int: The message length in bytes
getter/setter pairinherited
messageLengthInBits → int: Get the message length in bits
no setterinherited
pos ↔ int: The current position of data in the buffer
getter/setter pairinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sbuffer → Uint32List: The buffer as Uint32List
latefinalinherited

$finalize() → Uint8List: Finalizes the message digest with the remaining message block, and returns the output as byte array.
override
$process(List<int> chunk, int start, int end) → void: Processes a chunk of input data
override
$update([List<int>? block, int offset = 0, bool last = false]) → void: Internal method to update the message-digest with a single block.
override
add(List<int> data, [int start = 0, int? end]) → void: Adds data to the message-digest.
inherited
close() → void: Finalizes the message-digest. It calls digest method internally.
inherited
digest() → HashDigest: Finalizes the message-digest and returns a HashDigest
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reset() → void: Resets the current state to start from fresh state
override
toString() → String: A string representation of this object.
