DES Encryption Exercise

This project contains my implementation work for a DES (Data Encryption Standard) encyprtion completed in C.

Overview

• Convert my family name and student ID into binary and then hexadecimal,
• Apply required padding rules (family name to 64 bits, student ID to 56 bits),
• Add missing parity bits for the 56-bit DES key,
• Run the DES program to encrypt my family name using my student ID as the secret key.
