Tutorials

Have you ever wanted to make a secure IoT system? Then get started with this tutorial, to learn how to use some of the standard features of the SparkFun Cryptographic Co-processor! We will provide an introduction to cryptographic authentication, and then walk through the examples provided in the Arduino library. By the end, you will be able to create and verify digital signatures, use time-to-live tokens (aka NONCE), and have the tools and skills to add a very high level of authentication to all of your communication channels.
