More details

Description
This course teaches you how to build an RC5 symmetric block cipher in Rust. If you are interested in learning cryptography or how to build practical applications in Rust, this course is definitely for you.

The course is divided into three main sections:

In the first one, we will explain the theory of symmetric encryption and block ciphers. We will see what diffusion and confusion mean, and we will look into the details of the RC5 block cipher.
In the second, we will implement the RC5 cipher using Rust. We will learn how, with Rust-Generics, we can extend the capabilities of the cipher to words of 32, 64, and 128 bits without duplicating code.
In the third one, we will implement a real-world application that uses the RC5 cipher and cipher block chaining mode to encrypt and decrypt large files.
I recommend you program the RC5 cipher by yourself as you look at the video and also to create your own Github Repository. This will serve as a showcase for your future employers that you know what you are talking about and that you have Rust and Cryptography experience. Most important of all I also recommend you to have fun and ask every question you have!
