ECDSA

main.dart

import 'dart:io';
import 'package:silent_shard_sdk/silent_shard_sdk.dart' as sdk;

const port = 8080;
final nodeUri = Platform.isAndroid ? '10.0.2.2:$port' : '0.0.0.0:$port';

Future<void> exportKey(sdk.EcdsaSession session) async {
  // Creating a new keyshare for demo purpose. In real application, you can use an existing keyshare.
  final keyshare = await session.keygen();

  final privateKey = await session.export(keyshare: keyshare);
  print('Exported private key: $privateKey');
}

EdDSA

main.dart

import 'dart:io';
import 'package:silent_shard_sdk/silent_shard_sdk.dart' as sdk;

const port = 8080;
final nodeUri = Platform.isAndroid ? '10.0.2.2:$port' : '0.0.0.0:$port';

Future<void> exportKey(sdk.EddsaSession session) async {
  // Creating a new keyshare for demo purpose. In real application, you can use an existing keyshare.
  final keyshare = await session.keygen();

  final privateKey = await session.export(keyshare: keyshare);
  print('Exported private key: $privateKey');
}

• The export method takes an argument.
