Web@orange DES decryption works the same way as encryption, just with the round key order reversed (IP -> 16 rounds with k 16.. k 1 -> FP). Note that in DES, after the last (or before the first) round L i and R i are not swapped, making the entire structure easily reversible. The key scheduling algorithm can also be easily reversed. – Lukas how to store slurpee in refrigerator
