How can I implement encryption in my application?

To implement encryption, you can use libraries like OpenSSL or built-in functions in languages like Python or Java.

What type of encryption should I use, symmetric or asymmetric?

It depends on your use case. Symmetric encryption is faster and suitable for large data, while asymmetric is better for secure key exchange.

Can you give me an example of symmetric encryption in Python?

Sure! You can use the cryptography library. Here's a simple example:

from cryptography.fernet import Fernet

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

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

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