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(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.

ATTRIBUTES
