DESCRIPTION
The  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  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  function returns a pointer to the encrypted memory area.

ATTRIBUTES

CONFORMING TO
