KeyExchangeWand class abstract

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

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

Example

import 'package:cryptography/cryptography.dart';

Future<void> main() async {
  final x25519 = X25519();
  final aliceWand = await x25519.newKeyExchangeWand();
  final bobPublicKey = await (await x25519.newKeyPair()).extractPublicKey();
  final secretKey = await aliceWand.sharedSecretKey(
    remotePublicKey: bobPublicKey,
  );
}
