extendedPrivateKeyFromUri function

Future<List<int>> extendedPrivateKeyFromUri(
  1. String uri
)

Converts a URI to an extended private key.

Takes a URI as input and returns the corresponding extended private key as a list of integers. The URI is used to generate a public key and a private key using the ed25519 algorithm. The public key and private key are then concatenated to form the extended private key.

Implementation

Future<List<int>> extendedPrivateKeyFromUri(String uri) async {
  final publicKey = await publicKeyFromUri(uri);
  final privateKey = await privateKeyFromUri(uri);
  List<int> extendedPrivateKey = [];
  extendedPrivateKey.addAll(privateKey);
  extendedPrivateKey.addAll(publicKey);
  return extendedPrivateKey;
}
