NAME
memfrob - frobnicate (encrypt) a memory area
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */ #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 suitable only for hiding strings.
RETURN VALUE
The *memfrob*() function returns a pointer to the encrypted memory area.
