Originální popis anglicky:
memfrob - frobnicate (encrypt) a memory area
Návod, kniha: Linux Programmer's Manual
#include <string.h>
void *memfrob(void *s, size_t n);
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.
The
memfrob() function returns a pointer to the encrypted memory area.
The
memfrob() function is unique to the Linux C Library and GNU C
Library.
