Let's Encrypt is a new open source certificate authority that promises to provide free SSL certificates in a standardized, API accessible and non-commercial way. If you've installed SSL certificates in the past, you're probably familiar with the process of signing up for a certificate with some paid for provider and then going through the manual process of swapping certificate requests and completed requests.
This seems like a fabulous idea, given that securing your site if you have any sort of authenticated access is an absolute requirement. It's not so much the money that's a problem since basic SSL certificates these days even from paid providers are relatively cheap I use DnSimple both for domain management and SSL certificatesbut the fact that you can completely automate the process of SSL creation and management is a huge win. This has both upsides and downsides actually and I'll talk about that at the end of the article.
To be clear — I'm not a network admin and I don't have extensive experience managing certificates on a large number of sites so in this post I cover a few basic scenarios that I deal with in my own sites hosted on my own hosted servers.
I've followed the development of Let's Encrypt with interest, but there wasn't much to try initially as there was no implementation directly available for Windows.
Nik then goes on to describe an Azure plug-in implementation that can automatically register and renew Let's Encrypt certificates. This posts is a summary of what I found.
As is often the case with open tools, Windows is always the afterthought rather than the norm when it comes to open networking and security tools. So when Let's Encrypt initially went to beta there was no Windows support. This Windows Command Line utility includes an 'interactive' mode that lets you pick a host headered Web site on your server and will go out and create the certificate and install it into IIS in one seamless operation.
This works great for manual installation or simple scripted installs. It's quick and easy and by far the easiest solution I tried so far. Unlike the Win-Simple approach using the ACMESharp library requires a bit of scripting you have to write yourself with some logic, but you get a lot of control over the process and the ability to create and save the intermediate certificates.
Currently this tool is pretty rough, but improvements are coming and each new version seems to improve significantly. It's a great way to visually see certificates and obviously much easier for those that don't want to futz around with lots of command line foo. To be clear, all of these tools are in very early release stages and so they are a bit rough with features missing… and that's to be expected.
This stuff is new. Let's Encrypt itself is in beta and these tools build ontop of that base stack. What's missing in all tools currently is administration. You can't revoke or remove certificates and there's no way to clear out certificates on the remote servers. Because of this, I recommend if you plan to play with these tools, create a new host headered test site or sites with valid internet accessible domain names and play with that site before you update and add certificates to any live sites you care about.
Once you figure out how things work it's easy to get certificates installed on a live site. By far the easiest way to create and install a new certificate is LetsEncrypt-Win-Simple. This tool runs from the command line and has a few very easy to understand options.
Basically you pick a site from the list of active Web sites using host headers on your server and the utility goes out and creates a certificate for you, creates an https binding and attaches the certificate.Whether this is considered a bully tactic or not is not the point of this article but do realize that it will happen regardless. I will be using Windows 10 to perform the procedures. Rather than having to deal with certificate revocation and other security related issues such as a certificate being compromised, website owners can simply choose to generate a new certificate and let the old one naturally expire.
In order to obtain such certificates, the user or company go through a more rigorous validation process prior to the certificate being issued by the certificate authority.

You can see below the difference between a site secured with an EV certificate vs. The good news is that those restrictions are very loose and will rarely apply to most users. If however you need to secure multiple sub-domain names example. This should hopefully hold you over until wildcard support is available. It does involve a bit more work but I personally find this to be my validation method of preference.

Note that this is not your usual login account where you type in a username and password. Rather, this special key is used to validate your identity with. In essence, you can reuse this account key when requesting for certificates even with different domain names.
You do not need to generate a separate account key for every certificate you are requesting. Do keep this key safe after generating it here! Open a command prompt and drill into your OpenSSL bin directory and enter in the following command:. This key is the private half that makes up your certificate and should be kept in a safe location.
You should generate and use a new domain key for each new certificate that you are requesting for. We will next generate our CSR file. If you encounter an error, elevate your command prompt as administrator and try again. When asked for your email, challenge password and company name, simply hit Enter to skip it. Although not required, you can paste your CSR text file into a CSR decoder site such as this one to verify all the information, especially the common name field, is correct.
With our prerequisite files in hand, we can now request our certificate. To make things easier, move all three files account key, domain key and csr to the directory holding your ZeroSSL client executable. When ready, change to the directory holding the ZeroSSL client and enter in the command. You can use nslookup from a new command prompt to query for that record using a public DNS server such as Google:.
If successful, your certificate will be issued! It could be that their servers were slammed at the time I made my request as the procedures did not change one bit. I believe it launched in April of Wildcard support seems to be very near and that feature definitely will have a huge impact.What is CloudFlare ? - How To Convert HTTP websites into HTTPS for FREE - Configure CloudFlare CDN

So, when you "renew" your certificate, DigiCert must issue a new one to replace the expiring one, and you must install the new certificate on your server. To make renewing a certificate easier, DigiCert automatically includes the information from the expiring certificate in our renewal wizard.
However, because you're ordering a new certificate, you can update any of the information during the order process, if needed. You should also change the organization information in the CSR. For more information, see Create a CSR. A better way to provide authentication on the internet.

Can I trust them with my keys? If someone else were to obtain that private key, they could then produce SSL certificates pretending to be you, or revoke your existing certificates.
In the perfect world, only you should have access to your private key. If you have a script that you run on your own server, you can audit that script, and the key never goes off your server - that is the safest option.
The opposite and worst case is where you ask someone else to produce a private key for you, and they then give you a copy of the key. This means you need to completely trust them, their code and their servers. There are a couple of these systems available - which I would certainly not trust at all.
ZeroSSL falls in between these two scenarios, and it depends exactly how you use it. I think you can generate your own private key, on your own computer, and then use that to generate a csr again on your own computer. I have not audited the code in ZeroSSL. Thank you for your insight and addressing my concerns serverco. Some of what you said are my thoughts too. Certificates are signed documents, which say that the Issuer promises the Subject of the certificate has a private key which corresponds to this particular Public Key written down in the certificate.
CSR creation is often a point where people seem a bit lost, especially if that CSR is supposed to include more than one domain name. So the CSR generator was created, to ease the task. Seeing as there were still cases when people could not actually install the software at all or were unable or not allowed to do so, the in-browser client was added later to handle the whole process.
At the time there was just semi-manual, though still useful if you know what to do, gethttpsforfree. As explained on the site, the client is fully in-browser and the server is completely unaware of what you might be doing.
Actually, the server is not even using cookies or analytic services. Should you trust the service that might be creating something for you?
Trust is the key word here. You trust something on a daily basis - you trust online shops and Paypal with your data; you trust that your phone carrier or the apps on your phone are not collecting too much data, including your geolocation; you trust your hoster or some other entity with your driving license or some other form of id; etc.
That list is endless and you have to make choices. Many of those services and entities were at the beginning at some point or are now, but you have decided to trust them. If you feel uncomfortable - just follow the tech guides and use the clients you can install. But then again - without the code audit done and full understanding of how they work, can you absolutely trust them either? Or any programs on your computer or your phone to that matter? Even the services which seemed to be trustworthy may surprise you in a bad way, like it was recently with Web of Trust.
