DES Encryption Implementation with Trace

Core Features

• Encrypt a specified 64-bit (16 hex digit) data value with a 64-bit (16 hex digit) key using DES.
• Show Trace

Trace

• plain text and key in binary format
• subkeys generation process (subkeys in binary and hex format)
• DES encryption process
  • value after IP permutation
  • value after each iteration
  • value after IP-1 permutation

Please view the output-example.txt for more information about the output.

Usage

g++ des.cpp -o des  
./des
