🔐 CaesarJaw

📜 Description

This C++ program provides encryption and decryption functionalities using a simple shift cipher (Caesar cipher). It allows users to: ✅ Encrypt text 📝 ✅ Decrypt text 🔑 ✅ Determine the shift key 🔎 ✅ Attempt decryption without a known key 💡

✨ Features

• 🔏 Encryption (Crypt): Encrypts a given text using a specified key.
• 🔓 Decryption (UnCrypt): Decrypts an encrypted text using a specified key.
• 🕵️ Determine Shift Key: Finds the encryption key by comparing original and encrypted text.
• 🎭 Brute-Force Decryption: Attempts decryption by trying all possible shift keys.

🚀 Usage

Run the program and select an option: 1️⃣ Encrypt Text: Enter a switch key and the text to encrypt. 2️⃣ Decrypt Text: Enter a switch key and the text to decrypt. 3️⃣ Find Shift Key: Provide an encrypted and decrypted text to determine the shift key. 4️⃣ Brute-Force Decryption: Enter an encrypted text and see all possible decrypted results.

🛠️ Compilation & Execution

To compile the program using g++, run:

g++ -o cryptography_tool main.cpp

To execute:

./cryptography_tool

📝 Example

🔏 Encrypting a message

Enter Switch Key: 3
Please enter text: Hello123
Encrypted: Khoor456

🔓 Decrypting a message

Enter Switch Key: 3
Please enter text: Khoor456
Decrypted: Hello123

🔑 Determining the shift key

Please enter Crypt Text: Khoor456
Please enter UnCrypt Text: Hello123
Switch Key: 3
