Introduction

Today’s most widely used security toolkit is OpenSSL, not only due to its licensing terms (including a commercial use with no restrictions whatsoever) but due to its rich plethora of facilities and building blocks we can use to build any sophisticated cryptosystem.

It is also a rich learning tool, and despite its serious nature, we can use it to understand several basic questions like how internet banking works or how cryptocurrencies function. You can also learn fingerprinting and blockchain logic using the Linux command line and OpenSSL utility.

We talked about introductory OpenSSL in a previous blog Dipping Our Toes into OpenSSL, that covered how it supports rich cryptographic-centric operations, which are needed for all sorts of things in the security domain and even outside of it. Today, let's take the next step and understand some of the crypto arithmetic behind it, without making the topic too complicated.
