generateX25519EphemeralKeyPair function
Generates a X25519 ephemeral key pair. Returns a Future that completes with a tuple containing the private key and the public key.
Implementation
Future<(List<int>, List<int>)> generateX25519EphemeralKeyPair() async {
final algorithm = X25519();
final keyPair = await algorithm.newKeyPair();
final publicKey = await keyPair.extractPublicKey();
final privateKey = await keyPair.extractPrivateKeyBytes();
return (privateKey, publicKey.bytes);
}
