How can I encrypt data in a Flask application?

You can use libraries like Fernet from the cryptography package to encrypt data in Flask. Would you like a code example?

Yes, please provide a code example for encrypting and decrypting data.

Sure! Here's a simple example:

from cryptography.fernet import Fernet

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

# Encrypt data
original = b"Hello, World!"
encrypted = fernet.encrypt(original)

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

How do I store the encryption key securely?

You should store the key in a secure location, such as environment variables or a secrets management service, to prevent unauthorized access.
