The logic used in the DES rounds is the same as in the C code, +! except that calculations for sbox 1 and sbox 5 begin before +! the previous round is finished. +! +! In each round one half (work) is modified based on key and the +! other half (use). +! +! In this version we do two rounds in a loop repeated 7 times +! and two rounds seperately. +! +!

Each sbox entry contains the 4 output bits permuted +! into 32 bits according to the P permutation. +! +! In the description of DES, left and right are switched after +! each round, except after last round. In this code the original +! left and right are kept in the same register in all rounds, meaning +! that after the 16 rounds the result for right is in the register +! originally used for left. +! +!
