Read the key in two parts and XOR them inside the processor, that way
the actual key is only held inside the processor.
My point is whether it could be a security problem (due to presence of
some malicious processes, Trojan etc.) when something is read in,
since RAM is involved in reading, if I don't err. Whether the stuff is
read in in one shot or in two parts is secondary in my humble view.
