🚀 How to Use

1️⃣ Clone the Repository

git clone https://github.com/masfaatanveer/enigma-infosec.git
cd enigma-infosec

---

2️⃣ Run CLI Interface

python cli_interface.py

• Load default/custom configuration
• Enter initial key (e.g., MAS)
• Choose to encrypt/decrypt a message or file
• Optionally save updated configuration

---

3️⃣ Run GUI Interface

python gui_interface.py

• Enter message and key
• Select rotors and reflector
• Choose Encrypt or Decrypt
• Use "Process Message" or "Process File"
• Generate MD5 + SHA256 hash with one click

---

🔁 Example (Encryption & Decryption)

With same configuration and key (MAS):

Input Message: HELLO
Encrypted Message: XZLMP
Decrypted Message: HELLO

---

🔒 Hashing Example (via GUI)

For input MASFA:

#### Hashed Output:
MD5: bcf213325c01e1c47bd0622ac6a1eaf3
SHA256: 9bc72c58d0c6482ae79861fd0e5359fa8d8b5ecad32ce3c167155de3f7122a4e

---

🧪 Unit Testing

python -m unittest discover -s tests

• Verifies rotor mapping symmetry
• Ensures encryption == decryption
• Checks reflector logic

---

📊 Performance (Benchmarked)

Operation	Time
Encrypt message	Instant
File processing	< 1s (avg)
Save/load config	Instant
Run full tests	~0.3 sec
