MEMFROB(3)		   Linux Programmer's Manual		    MEMFROB(3)

NAME
       memfrob - frobnicate (encrypt) a	memory area

SYNOPSIS
       #include	<string.h>

       void *memfrob(void *s, size_t n);

DESCRIPTION
       The  memfrob() function encrypts	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 encrypted memory area.

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

RETURN VALUE
       The memfrob() function returns a	pointer	to the encrypted memory	area.

CONFORMING TO
       The memfrob() function is unique	to the Linux C Library and GNU	C  Li-
       brary.
