What is Understanding DES Encryption Process about?

DES operates on 64-bit plaintext blocks by performing an initial permutation and then 16 rounds of encryption using 48-bit subkeys generated from a 56-bit encryption key. Each round takes the left and right halves of the encrypted block from the previous round, and uses one of the subkeys and an expansion-permutation function to calculate the new right half, while the left half is simply moved to the right. After 16 rounds the final left and right halves are recombined and undergo a final permutation to pro
