WebFeb 26, 2024 · The DES encryption Algorithm. DES is a block Cipher, which means that it takes a fixed-length string of plaintext bits and transforms it through a series of complicated operations. 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
