             Before you can use this test you have to get credentials at <a href="https://gateway.threema.ch" title="Threema Gateway">gateway.threema.ch</a> and <a href="https://github.com/rugk/threema-msgapi-sdk-php/wiki/How-to-generate-a-new-key-pair-and-send-a-message">create a key pair</a>. After you did so, you have to open <code><?php echo FILENAME_CONNCRED . FILEEXT_EXAMPLE ?></code> and <code><?php echo FILENAME_PRIVKEY . FILEEXT_EXAMPLE ?></code> and add your credentials and private key. Save them without the <code><?php echo FILEEXT_EXAMPLE ?></code> file extension afterwards.
             By default these files are excluded from git pulls so you will not accidentally publish these sensitive files.
