What are some examples of encryption in Django?

Django provides several ways to handle encryption, such as using the built-in cryptographic signing and the Fernet symmetric encryption.

Can you show me a code example using Fernet encryption?

Sure! Here's a simple example:

from cryptography.fernet import Fernet

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

# Encrypt a message
message = b"Hello, World!"
encrypted = fernet.encrypt(message)

# Decrypt the message
decrypted = fernet.decrypt(encrypted)
print(decrypted.decode())  # Output: Hello, World!

How do I securely store the encryption key?

You can store the encryption key in environment variables or use a secrets management service to keep it secure.

Are there any libraries you recommend for encryption in Django?

Yes, the cryptography library is highly recommended for encryption tasks in Django due to its simplicity and security features.
