Fortunately, OpenSSL makes it easy to complete one. You can’t get an SSL certificate issued without a CSR. Use the following command line check OpenSSL Version: openssl version -a OpenSSL Commands Lines for Generating a CSR This will be even more important when TLS 1.3 rolls out, as you’ll need to make sure your OpenSSL implementation supports it. That’s called foreplay.Īnyway, figuring out what version of OpenSSL you’re working with lets you know about what it’s compatible with. And even if you already know, sometimes it’s nice just to ask the server a few questions about itself before you start bossing it around. Sometimes you’ll need to identify which version of OpenSSL is being used on a given server. So say goodbye to the Pythagorean theorem and say hello to… this. That’s right, today we’re going to forget some relevant information so we can make space in our brains for some random strings of text that a computer will understand. So that means we need to learn some command lines. And Google hasn’t pulled a wet job since it whacked Jeeves. Now, I know what you’re asking: “can’t I just generate a private key and a CSR in my browser with an online tool?” No. About two-thirds of all web servers are using OpenSSL. It’s written in the programming language, C, though there are wrappers available for a wide range of computer languages. It includes tools for generating Certificate Signing Requests and Private Keys. It’s a robust, full-featured toolkit for the open-source implementation of the SSL and TLS protocols.

OpenSSL is a software library, a cryptography library to be exact. Today, we’re here to discuss OpenSSL command lines. But that’s another discussion for another time. Millenials are the worst thing to ever happen to Applebee’s. Probably one that can’t attract millennial customers. Writing a comprehensive guide to OpenSSL commands seems an odd job to give an aging man who, up until recently, thought servers could only be found hoofing it from kitchen to table in a chain restaurant.
