NAME
memfrob - frobnicate (obfuscate) a memory area
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
bash
#define _GNU_SOURCE\n /* See feature_test_macros(7) */
\n#include <string.h>bash
void *memfrob(void \ns\n[.\nn\n], size_t \nn\n);DESCRIPTION
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.
RETURN VALUE
The memfrob() function returns a pointer to the obfuscated memory area.
