CyberHashira | OpenSSL Tutorial Series

This repository contains notes for my OpenSSL tutorial videos on YouTube. Within these notes, you'll find the commands I used in those videos, along with some extra information to explain their purpose. At the time of recording, I was using OpenSSL version 1.1.1, which is set to reach End-of-Support in September this year. While I believe that most of the OpenSSL 1.1.1 commands used in my videos should still function in OpenSSL 3.x.x, there might be some minor differences. Rest assured, I'm committed to keeping my notes as up-to-date as frequently as possible. If necessary, I'll remake any outdated videos to explain the changes.

Sample codes

I have also written several sample programs that demonstrate how to perform various cryptographic operations using the OpenSSL API. These samples were written using the latest OpenSSL 3.5 API.
