getAuthConfig method

Future<AuthConfig> getAuthConfig()

Retrieves the authentication configuration from a Mifare Ultralight C RFID tag.

This method reads the authentication configuration data from the RFID tag, including the starting block for authentication and the lock status. It encapsulates this information in an AuthConfig object for easy access and manipulation.

Returns

A Future<AuthConfig> that resolves to an AuthConfig object containing the authentication configuration details of the tag.

Throws

  • RFIDException if there's an error during the read operation. This could be due to communication issues with the RFID reader or problems interpreting the data from the tag.

Example

try {
  AuthConfig config = await card.getAuthConfig();
  print('Starting block for authentication: ${config.startingBlock}');
  print('Lock status: ${config.lock}');
} catch (e) {
  print('Failed to get authentication configuration: $e');
}

Note: The authentication configuration is crucial for understanding and managing how authentication operations are performed with the RFID tag. This method provides a straightforward way to access these settings, aiding in secure and effective tag management.

Implementation

Future<AuthConfig> getAuthConfig() async {
  try {
    final data = await reader.readBlock(
      blockNumber: AUTH_CONFIG_ADDRESS_START,
      length: BLOCK_SIZE * 2,
    );

    return AuthConfig(
      startingBlock: data[0],
      lock: AuthLock.fromInt(data[4]),
    );
  } catch (e) {
    throw RFIDException('Error getting authentication configuration');
  }
}
