Sha512 class abstract

SHA-512 HashAlgorithm (sometimes called SHA2-512).

In browsers, the default implementation will use Web Cryptography API. On other platforms, DartSha512 will be used.

Asynchronous usage (recommended)

import 'package:cryptography_plus/cryptography_plus.dart';

Future<void> main() async {
  final message = <int>[1,2,3];
  final algorithm = Sha512();
  final hash = await algorithm.hash(message);
  print('Hash: ${hash.bytes}');
}

If you really need synchronous computations, use DartSha512.

Streaming usage

This enables you to handle very large inputs without keeping everything in memory:

import 'package:cryptography_plus/cryptography_plus.dart';

void main() async {
  // Create a sink
  final algorithm = Sha512();
  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}');
}
