How can I securely encrypt my API keys?

You can use various methods to encrypt your API keys, such as using environment variables or encryption libraries.

What encryption libraries do you recommend?

I recommend libraries like AES for symmetric encryption or RSA for asymmetric encryption, depending on your needs.

Can you show me a code example for AES encryption?

Sure! Here's a simple example in Python using the PyCryptodome library:

from Crypto.Cipher import AES
from Crypto.Util.Padding import pad
import os

key = os.urandom(16)  # Generate a random 16-byte key
cipher = AES.new(key, AES.MODE_CBC)

plaintext = b'my_api_key'
ct_bytes = cipher.encrypt(pad(plaintext, AES.block_size))
