🧰 Prerequisites

You need to install MSYS2 to get the required C/C++ compilers.

🔽 Steps to Install MSYS2

1. Visit https://www.msys2.org.

2. From the Installation section, click on msys2-x86_64.exe to download the installer.

3. Run the installer and complete the installation.

4. A black MSYS2 terminal will pop up — do not close it.

5. In the terminal, run the following command:

   pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain

6. Press Enter to select defaults.

7. Type y to confirm installation and let the tools download and install.

📝 command to run this algorithms

g++ main.cpp encryption.cpp -o run

---

📝 How It Works

1️⃣ Choose the encryption method.
2️⃣ Input the text or file to be encrypted.
3️⃣ Provide a secure key (if applicable).
4️⃣ Get the encrypted output.
5️⃣ Decrypt using the correct key.

---

📌 Example Usage

🔒 Encrypt a message:

Enter text to encrypt: Hello World
Choose algorithm (AES, RSA, Caesar): AES
Enter key: mysecurekey
Encrypted Output: Xk9sI3zB2...

🔓 Decrypt a message:

Enter encrypted text: Xk9sI3zB2...
Choose algorithm: AES
Enter key: mysecurekey
Decrypted Output: Hello World
