How can I implement cryptography in my Django application?

You can use the cryptography library in Django to handle encryption and decryption. Would you like a code example?

Yes, please provide a code example for encrypting user passwords.

Sure! You can use the following code:

from cryptography.fernet import Fernet

# Generate a key
key = Fernet.generate_key()
fernet = Fernet(key)

# Encrypt a password
password = b'my_secret_password'
encrypted_password = fernet.encrypt(password)

# Decrypt the password
decrypted_password = fernet.decrypt(encrypted_password)

How do I securely store the encryption key?

It's best to store the encryption key in an environment variable or a secure vault service like AWS Secrets Manager.
