isValid property

@override bool get isValid

Validates the integrity of this metadata.

Important: Must be called when receiving new metadata from the network to verify the fingerprint matches the seed and public key.

Returns true if fingerprint is valid (signature matches seed and public key), false otherwise (invalid or tampered metadata).

Implementation

@override
bool get isValid {
  if (_status == 0) {
    // meta from network, try to verify
    if (checkValid()) {
      // correct
      _status = 1;
    } else {
      // error
      _status = -1;
    }
  }
  return _status > 0;
}
