# 🔐 Simple Symmetric Encryption in Python
3+
4+
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**.
5+
6+
---
7+
8+
## 📚 What You'll Learn
9+
10+
- How to generate secure keys
11+
- How to encrypt and decrypt messages
12+
- Basic key management (saving & loading keys)
13+
- How `Fernet` (AES-based encryption) works under the hood
14+
15+
---
16+
17+
## 🚀 Getting Started
18+
19+
### 1. Clone the Repository
20+
21+
```bash
22+
git clone https://github.com/your-username/simple-encryption-python.git
23+
cd simple-encryption-python
24+
```
25+
26+
### 2. Install Dependencies
27+
28+
Make sure you have Python 3.6+ installed.
29+
30+
Install required package using `pip`:
31+
32+
```bash
33+
pip install cryptography
34+
```
35+
36+
### 3. Run the Code
37+
38+
```bash
39+
python simple_encryption.py
40+
```
41+
42+
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:
43+
- Loads the existing key
44+
- Encrypts a sample message
45+
- Decrypts it back and displays the result
46+
47+
---
48+
49+
## 📂 File Structure
50+
51+
```
52+
simple-encryption-python/
53+
│
54+
├── simple_encryption.py # Main script to run encryption and decryption
55+
├── secret.key # Auto-generated AES-based symmetric key (DO NOT SHARE)
56+
├── README.md # Documentation
57+
```
58+
59+
---
60+
61+
## 🔒 Security Note
62+
63+
This example is for educational purposes only. If you’re building a production-grade application:
64+
- Never store raw keys in plaintext
65+
- Use environment variables or secure vaults (e.g., AWS KMS, HashiCorp Vault)
66+
- Handle exceptions and errors securely
67+
68+
---
69+
70+
## 🧠 How It Works (In Brief)
71+
72+
- **Fernet** is a module in the `cryptography` package that provides:
73+
- AES-128 in CBC mode
74+
- HMAC-SHA256 authentication
75+
- Random IVs for each encryption
76+
77+
- The encryption key is:
78+
- Generated once and saved to `secret.key`
79+
- Loaded on subsequent runs
80+
81+
- The message is:
82+
- Encrypted using `.encrypt()`
83+
- Decrypted using `.decrypt()`
84+
85+
---
86+
87+
## 💡 Sample Output
88+
89+
```
90+
[*] Key loaded from 'secret.key'
91+
92+
Original Message: This is a secret message.
93+
Encrypted Message: b'gAAAAABlZ...'
94+
Decrypted Message: This is a secret message.
95+
```
96+
