/*
 * TODO:
 *
 * - Utilize prefetch.
 *
 * - Implement loop in CBC operations.  Take an argument of the number of
 *   blocks.  Better if prefetch is used too.
 *
 * - In AES and DES buffer block loop, merge encrypt / decrypt.  Take a
 *   direction argument (int dir, 0 => encrypt, 1 => decrypt) then branch.
