Hi,

stunnel parses the configuration file and sends the PIN to OpenSSL's
engine with the engine_ctrl() function defined in options.c:

     if(!ENGINE_ctrl_cmd_string(engines[current_engine], cmd, arg, 0)) {
         sslerror("ENGINE_ctrl_cmd_string");
         return "Failed to execute the engine control command";
     }

stunnel does not store the PIN after sending it to the OpenSSL's engine.
