Using only the default values, you will end up with a 2048 bit certificate valid for 3 months. The installation process and creation of the Let’s Encrypt environment takes a couple of minutes.

This will install quite a few additional packages onto your machine, which is also in part why I prefer to do this on a separate machine. I will assume that your user is allowed to sudo, which is the case if you provisioned the Ubuntu machine according to the above.įirst, install a git cd.

Now, using an SSH client, log into your machine (using the user name and password you provided when provisioning it). Setting up your Ubuntu machine for Let’s Encrypt This is highly depending on your DNS provider, so this is left out here.

If you don’t know how to do this, contact your IT department or somebody else who knows how to do it. Pinging must resolve to your Ubuntu machine. Now that you have a running Ubuntu machine we can play with, make sure the desired host name resolves to the Ubuntu VM DNS name from the above picture.

The automatically created DNS entry for your machine is displayed there, and this is the name you can use to connect to the machine using your favorite SSH tool ( ssh if you’re on Linux or Mac OS X, e.g PuTTY if you’re on Windows). This will take some time (around 5 minutes), but after that, you will find the information on your machine in the following way: This is the only cost though you will generate when creating the certificate. Note: You will be charged for running the VM on Azure. When you’re done and all your settings have been confirmed ( OK), click the Create button to provision your VM. Leave the rest of the setting to the defaults.Add two endpoints: http (tunnel port 80) and https (tunnel port 443).
Standard A1 (1,75 GB of RAM, 1 Core, completely sufficient).Choose Password and enter a valid password.Hostname letsencrypt (Azure will pick a name for you starting with letsencrypt).Then, search for ubuntu and select Ubuntu Server 14.04 LTS (I think you can choose a regular Ubuntu, too, but this one definitely works). Then click Virtual machines (Classic), then Add +.
To start things, open up the Azure Portal using your favorite web browser, and log in so that you have access to the Azure portal. I will assume throughout this blog post. You need to know which DNS name you want for your certificate.Know-how on how to create a CNAME (DNS entry) for your machine (I usually delegate this to our friendly IT, they know that by heart).A valid Azure Account and some credit to play with (depending on how fast you are, you will need something between 10 Cents and a Euro/Dollar).You will need the following things, which this how-to does not provide you with: It’s just what I currently have at hand (as I have an MSDN subscription). Please note that Let’s Encrypt in no way depends on the VM being provisioned on Azure. This how-to really starts with Adam and Eve, so if you already have an Ubuntu machine you can play with, and which is reachable from the public internet, you can skip the provisioning part on Azure. This post will describe how you can leverage a simple Azure Ubuntu VM to create a certificate for any domain you can control yourself (create a CNAME entry for). This means you can actually use Let’s Encrypt to create real SSL certificates which will be accepted as valid by web browsers and others.
Let’s Encrypt is a new Certificate Authority which has a couple of benefits almost unheard of before: It’s free, automated and open.
