For the purposes of encryption, this probably
won't be a problem, because you won't likely
be using the value in a context where it will
be promoted, nor will you likely be comparing
greater-than/lesser-than (just bit-shifting,
xor'ing, and other bit-wise stuff).
If you have to perform math, such as addition
and subtraction, then use a "short", which
is 16-bits, where you can just mask-off the
higher 8-bits.
