       The  memfrob()  function  obfuscates  the  first  n  bytes  of  the memory area s by exclusive-ORing each
       character with the number 42.  The effect can be reversed by using memfrob()  on  the  obfuscated  memory
       area.

       Note  that this function is not a proper encryption routine as the XOR constant is fixed, and is suitable
       only for hiding strings.
