🔒 File Encryption and Decryption 🔓

This Python program includes two scripts, 📜 encrypt.py and 📜 decrypt.py, designed for encrypting and decrypting text files using the Fernet encryption scheme from the cryptography library.

How it Works 🛠️

encrypt.py 🌐

The encrypt.py script follows these steps:

1. Gets the current directory.
2. Identifies all text files (files with a '.txt' extension) in the directory.
3. Generates a Fernet key.
4. Writes the key to a file named key.key.
5. Encrypts the content of each text file using the generated key.

decrypt.py 🔓

The decrypt.py script follows these steps:

1. Gets the current directory.
2. Identifies all encrypted text files in the directory (files with a '.txt' extension).
3. Reads the Fernet key from the key.key file.
4. Decrypts the content of each encrypted text file using the stored key.

Requirements 📋

• Python
• cryptography library

Install the required library using:

pip install cryptography

Contribution 🤝

Feel free to contribute to the project by opening issues or submitting pull requests. Follow the guidelines outlined in CONTRIBUTING.md.

How to Run ▶️

Encryption 🔐

Run the encryption script using a Python interpreter:

python encrypt.py

Decryption 🔓

Run the decryption script using a Python interpreter:

python decrypt.py

Key Storage 🗝️

The encryption key is generated and stored in a file named key.key during the encryption process. This key file is crucial for decryption. Ensure its security and do not share it with encrypted files.

Important Security Information ⚠️

• Keep the encryption key (key.key) secure.
• Do not share the key or store it with the encrypted files.
• Losing the key will result in permanent data loss as decryption will not be possible.

Caution: Use this encryption method responsibly, and always keep a secure backup of your key.
