Rearranges the 64 bits of the input block.
This guide covers the and its more secure successor, Triple DES (3DES) . Both are symmetric-key block ciphers that encrypt data in 64-bit blocks. 1. Data Encryption Standard (DES) DES and 3DES
The inverse of the initial permutation to produce the final ciphertext. 2. Triple DES (3DES) Rearranges the 64 bits of the input block
56-bit effective key length (plus 8 parity bits for a total of 64 bits). Block Size: 64 bits. Process Steps: XOR with a subkey
Each of the 16 rounds involves expansion, XOR with a subkey, substitution (via S-boxes), and permutation.
