memfrob(3)

NAME
memfrob - frobnicate (obfuscate) a memory area

LIBRARY
Standard C library (libc, -lc)

SYNOPSIS
#define _GNU_SOURCE             /* See feature_test_macros(7) */
#include <string.h>

void *memfrob(size_t n;
              void s[n], size_t 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.
