SignatureWand class abstract

An opaque object that has some key pair and support for sign.

You can extract the PublicKey with extractPublicKeyUsedForSignatures. The private key is not extractable.

Example

import 'package:cryptography/cryptography.dart';

Future<void> main() async {
  final ed25519 = Ed25519();
  final wand = await ed25519.newSignatureWand();
  final signature = await wand.sign(someData);
}
