      * krand - use internal kam_rand() function
-     * fastrand - use internal fastrand function
-     * cryptorand - use internal cryptorand (fortuna) function

      * kxlibssl - default libssl rand engine wrapped by a Kamailio mutex
 
    Note: the krand and fastrand engines are not recommended for use on
    systems requiring strong security, as they may not generate numbers
