Sha224 class abstract
SHA-224 (SHA2-224) HashAlgorithm.
By default, DartSha224 will be used.
Asynchronous usage (recommended)
import 'package:cryptography/cryptography.dart';
Future<void> main() async {
final message = <int>[1,2,3];
final algorithm = Sha224();
final hash = await algorithm.hash(message);
print('Hash: ${hash.bytes}');
}
If you really need synchronous computations, use DartSha224.
Streaming usage
This enables you to handle very large inputs without keeping everything in memory:
import 'package:cryptography/cryptography.dart';
void main() async {
// Create a sink
final algorithm = Sha224();
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}');
}
