+# 🔐 Simple Symmetric Encryption in Python
+
+This project demonstrates the basics of **symmetric encryption** using Python and the [`cryptography`](https://cryptography.io/en/latest/) library. It's a great starting point for beginners interested in **cybersecurity**, **cryptography**, or contributing to **open-source security tools**.
+
+---
+
+## 📚 What You'll Learn
+
+- How to generate secure keys
+- How to encrypt and decrypt messages
+- Basic key management (saving & loading keys)
+- How `Fernet` (AES-based encryption) works under the hood
+
+---
+
+## 🚀 Getting Started
+
+### 1. Clone the Repository
+
+```bash
+git clone https://github.com/your-username/simple-encryption-python.git
+cd simple-encryption-python
+```
+
+### 2. Install Dependencies
+
+Make sure you have Python 3.6+ installed.
+
+Install required package using `pip`:
+
+```bash
+pip install cryptography
+```
+
+### 3. Run the Code
+
+```bash
+python simple_encryption.py
+```
+
+On first run, it will generate a `secret.key` file that is used for both encryption and decryption. Each time you run the script, it:
+- Loads the existing key
+- Encrypts a sample message
+- Decrypts it back and displays the result
+
+---
+
+## 📂 File Structure
+
+```
+simple-encryption-python/
+│
+├── simple_encryption.py   # Main script to run encryption and decryption
+├── secret.key             # Auto-generated AES-based symmetric key (DO NOT SHARE)
+├── README.md              # Documentation
+```
+
+---
+
+## 🔒 Security Note
+
+This example is for educational purposes only. If you’re building a production-grade application:
+- Never store raw keys in plaintext
+- Use environment variables or secure vaults (e.g., AWS KMS, HashiCorp Vault)
+- Handle exceptions and errors securely
+
+---
+
+## 🧠 How It Works (In Brief)
+
+- **Fernet** is a module in the `cryptography` package that provides:
+  - AES-128 in CBC mode
+  - HMAC-SHA256 authentication
+  - Random IVs for each encryption
+
+- The encryption key is:
+  - Generated once and saved to `secret.key`
+  - Loaded on subsequent runs
+
+- The message is:
+  - Encrypted using `.encrypt()`
+  - Decrypted using `.decrypt()`
+
+---
+
+## 💡 Sample Output
+
+```
+[*] Key loaded from 'secret.key'
+
+Original Message: This is a secret message.
+Encrypted Message: b'gAAAAABlZ...'
+Decrypted Message: This is a secret message.
+```
+
