Strong encryption conceals data even against determined adversaries, such as enemy military agencies, if done correctly. The two main methods of strong encryption are AES and RSA, which are both approved by the US government. You do not need to have programming experience to learn this, and you don't need any special computer; any computer that can run Python can do these projects. Also, you don't need much math because we are not going to be inventing new encryption techniques just to learn how to use the standard pre-existing ones that don't require anything more than very basic algebra.
In this chapter, we will cover  pre-existing:
- Strong encryption with AESÂ
- ECB and CBC modes
- Padding oracle attack
- Strong encryption with RSAÂ
- What's next?
