Strong encryption with RSA

In this section, we will cover public key encryption, the RSA algorithm, and implementation in Python.

Public key encryption

In public key encryption, we solve this problem: Google, for example, wants to receive confidential data from users, such as passwords and credit card numbers, but they don't have a secure communication channel; what they have is the public internet, and any data being sent might be eavesdropped upon by any number of attackers. Thus, there's no way to deliver a shared secret key, and symmetric encryption algorithms, such as AES, cannot solve this problem. That's where public key encryption comes in.
