ExtendedKey.deserialize constructor

ExtendedKey.deserialize(String key)

Take a HD key serialized according to the spec and deserialize it.

Works for both private and public keys.

Implementation

factory ExtendedKey.deserialize(String key) {
  var decodedKey = Base58Codec(alphabet).decode(key);
  if (decodedKey.length != lengthOfSerializedKey + lengthOfChecksum) {
    throw InvalidKeyLength(
        decodedKey.length, lengthOfSerializedKey + lengthOfChecksum);
  }

  if (equal(decodedKey.getRange(0, 4), privateKeyVersion)) {
    return ExtendedPrivateKey.deserialize(Uint8List.fromList(decodedKey));
  }

  return ExtendedPublicKey.deserialize(Uint8List.fromList(decodedKey));
}
