The process of using the crypto module to perform encryption and decryption with a public-private key pair typically involves the following steps:

1. Generate a key pair: Use the crypto module to generate a public-private key pair. This typically involves creating an instance of the RSA key object using the generate_key_pair method.

2. Encrypt data: Use the public key to encrypt the data that you want to send securely. This is typically done using the encrypt method, which takes in the data and the public key as arguments.

3. Decrypt data: Use the private key to decrypt the encrypted data. This involves using the decrypt method with the encrypted data and the private key as arguments.

It's important to note that this process also typically involves converting the public and private keys from their initial binary format to a more user-friendly format, such as PEM or DER. There are methods available in the crypto module to assist with this conversion, such as public_key_to_pem and private_key_to_pem.
