verify method

  1. @override
Future<bool> verify(
  1. List<int> input, {
  2. required Signature signature,
})
override

Verifies whether bytes was signed with signature.

Example

In this example, we use Ed25519:

import 'package:cryptography/cryptography.dart';

Future<void> main() async {
  final signedMessage = [1,2,3];

  final ed25519 = Ed25519();
  final keyPair = await ed25519.newKeyPair();
  final signature = await ed25519.sign(
    signedMessage,
    keyPair: keyPair,
  );

  // ...

  final isRealSignature = await ed25519.verify(
    signedMessage,
    signature: signature,
  );

  print('Signature verification result: $isRealSignature');
}

Implementation

@override
Future<bool> verify(
  List<int> input, {
  required Signature signature,
}) async {
  return verifySync(input, signature: signature);
}
