DES Cryptosystem

CS3004 - Securing Information Systems

Final Project

DES Cryptosystem Implementation

---

1. Usage:
   • // TODO: ...
2. Syntax for the 'config' file:
   • operation=encrypt|decrypt|verify
   • mode=CBC|ECB
   • format=ASCII|BASE64
3. Provided examples: Our project includes a folder called "Examples" which includes three different sample files which can be used in order to test the capababilities of our implementation. In Each example there is a sample of the cyphered data (as a BASE64 encoded file - as requested), and a sample file which contains the expected data after decrypting the encrypted file.
