What are some examples of using the Django cryptography library?

The Django cryptography library provides various tools for encrypting data. For example, you can use it to encrypt user passwords or sensitive information.

Can you show me how to encrypt a password using this library?

Sure! You can use the make_password function from django.contrib.auth.hashers to encrypt a password. Here's a simple example:

from django.contrib.auth.hashers import make_password

password = 'my_secure_password'
encrypted_password = make_password(password)
print(encrypted_password)

What about decrypting data? Is that possible?

In general, password hashing is one-way, meaning you can't decrypt it. However, if you use symmetric encryption, you can decrypt data using the same key. Would you like an example of that?

Yes, please provide an example of symmetric encryption.

Here's an example using the Fernet class from the cryptography library:

from cryptography.fernet import Fernet

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

# Encrypt data
original = b'my secret data'
encrypted = fernet.encrypt(original)

# Decrypt data
decrypted = fernet.decrypt(encrypted)
print(decrypted.decode())
