How resistant to side-channel attacts is or can be an implementation of
your algorithm? Not being an expert I am a bit worried about this
particular line 

    XORVal ^= *(Salt + (LastVal&(SALT_SIZE-1)));

which if I understand it correctly makes a memory access depending on
secret data. Because memory accesses are note constant time operations
due to cache one might try (and succeed?) learning about secrets by
measuring time required to encrypt or decrypt data.
