WebMar 13, 2024 · We have mentioned that DES uses a 56-bit key. Actually, The initial key consists of 64 bits. However, before the DES process even starts, every 8th bit of the key is discarded to produce a 56-bit key. That … Web1. in first instruction it swap the 16 bits sets (ie word length) and in second instruction it swaps the 8 bits sets (ie character length) resulting in big endian to little endian and vice versa conversion. Output will be : 23EFCDAB. and yeah the benefit is no extra variable and less steps. – Saurabh Sengar. Web3. Just use a temporary variable and move the last bit into that variable, then shift the bit in that direction and end of masking in the bits in the tmp var and you are done.
