@override Future<bool> equals(PrivateKey other)

Checks if this private key is equal to another

Implementation

@override
Future<bool> equals(PrivateKey other) async {
  if (other is! Ed25519PrivateKey) return false;

  // Try to compare the raw bytes if available
  try {
    final thisBytes = raw;
    final otherBytes = other.raw;
    return _bytesEqual(thisBytes, otherBytes);
  } catch (e) {
    // Fall back to comparing public keys
    return publicKey.equals(other.publicKey);
  }
}
