Section (3) memfrob
memfrob — frobnicate (encrypt) a memory area
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h>
encrypts the first
bytes of the memory area
s by exclusive-ORing each
character with the number 42. The effect can be reversed by
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.
For an explanation of the terms used in this section, see attributes(7).
