-/**
- * @brief applies a crypto transform
- *
- * The function pointer xfm_func_t points to a function that
- * implements a crypto transform, and provides a uniform API for
- * accessing crypto mechanisms.
- * 
- * @param key       location of secret key                  
- *
- * @param clear     data to be authenticated only           
- *
- * @param clear_len length of data to be authenticated only 
- *
- * @param iv        location to write the Initialization Vector (IV)
- *
- * @param protect   location of the data to be encrypted and
- * authenticated (before the function call), and the ciphertext
- * and authentication tag (after the call)
- *
- * @param protected_len location of the length of the data to be
- * encrypted and authenticated (before the function call), and the
- * length of the ciphertext (after the call)
- *
- * @param auth_tag   location to write auth tag
