Blake2b class abstract

BLAKE2B (RFC 7693) HashAlgorithm.

Asynchronous usage

import 'package:better_cryptography/better_cryptography.dart';

Future<void> main() async {
  final algorithm = Blake2b();
  final message = <int>[1,2,3];
  final hash = await algorithm.hash(message);
  print('Hash: ${hash.bytes}');
}

If you need synchronous computations, use DartBlake2b.

Streaming usage

import 'package:better_cryptography/better_cryptography.dart';

void main() async {
  final algorithm = Blake2b();

  // Create a sink
  final sink = algorithm.newSink();

  // Add any number of chunks
  sink.add(<int>[1,2,3]);
  sink.add(<int>[4,5]);

  // Calculate the hash
  sink.close();
  final hash = await sink.hash();

  print('Hash: ${hash.bytes}');
}

In need of synchronous APIs?

If you need to perform operations synchronously, use DartBlake2b in package:better_cryptography/dart.dart.
