For most browsers and operating systems, yes. See the compatibility list for more detail. Certbot automatically requests certificates for multiple names when requested to do so. The resulting certificates will be accepted by browsers for any of the domain names listed in them. Certbot has added support for wildcard certificates as of version 0. Note that depending how you install Certbotappropriate plugins to automate the process may not yet be available on your system.
Information about the DNS plugins is available in the Certbot documentation. However, certificates obtained with a Certbot DNS plugin can be renewed automatically. There are a large number of other client implementations available too. This website provides information about the level of support for various web servers and operating systems, which varies and is increasing over time.
On supported systems, the automated configuration makes it fast and easy to obtain, install, and automatically renew certificates. If automated configuration is not supported for your web server, you can still get a certificate using Certbot and configure your server software manually. In this case, the certificate will not be renewed automatically. Note that automated configuration is not required. It can be disabled if you prefer to configure your server software yourself.
The webroot and manual plugins work well without root privileges. The certbot-auto script works on the assumption that root privileges will be used, both in order to install OS dependencies where required and because it needs to support all of the plugins mentioned above.
The packaged versions of Certbot are more flexible, and some of the teams building these packages are working toward having Cerbot run with group rather than root privileges where possible.Best th13 legend base 2020
You can obtain a certificate for an existing CSR, which means you may generate your own CSR using your own private key. However, Certbot will not accept a private key as input and generate a CSR for you.Get the latest tutorials on SysAdmin and open source topics. Hub for Good Supporting each other to make an impact.

Step one was to fix a failing backup jobs on my Synology NAS. As usual, things escalated. This blog post has nothing really to do with that backup job, which turned out to be an easy fix make more space for bigger files. You see, fixing that gave me new confidence to tackle other sysadmin issues. Whilst I was already working on the NAS I figured it was time to put an actual trusted SSL certificate in place so accessing the admin UI no longer forces me to accept this warning every time….
For those with a Synology NAS hopefully this blog post provides some useful information, or at least some entertainment! I had a poke around but my attempt to get a certificate failed. I need another option. If I want a cert for important.
This fits my use case where I have mynas. I could probably just knock up something to write the TXT record and remove it afterwards. Well, unsurprisingly, someone has already done this and produced a certbot plugin, certbot-dns-cloudflare.
How do you install a certbot plugin on the Synology NAS? I also ran an rsnapshot variation on this box years ago, but nothing much more than that. A quick Google pointed me at opkg as an available package manager.
Now with opkg installed I was able to ssh to the NAS and install the certbot-dns-cloudflare plugin requirements and the plugin itself:. Back in a web browser I headed over to Cloudflare. The second is to grab the API key. For those following along this can be found on your profile page top right menuthen your global API key is at the bottom of the page. This needs to be stored on the NAS in an ini configuration file, e.
As an aside, be careful with this API key! At least not that I could see on the free plans. The steps above took longer than expected.
A Story about Let’s Encrypt and my Synology NAS
With a certificate ready to go I was now hoping for a 2 minute task to get the NAS using it, alas this also turned out to be more involved. For starters, the DSM admin interface lets you import a certificate but only via a file upload, which is no good from the perspective of future automatic renewals. It is good news to see nginx running rather than some little-known web server. The SSL certificate reference is near the top. With that done I loaded up my browser and… the old cert was still being served!
Trying to play along with this way of doing things, I copied my new certificate and private key over the top of the Synology ones so the config file could stay the same. I figured I could automate the copy as a certbot hook after renewal.
I restarted nginx again and… still the old cert. This time the certificate files were reset back to their original content!! Keen to force my approach to work I turned to the big guns, making the certificate files immutable. This can be achieved with chattr.Wie schütze ich meine DiskStation mit Let's Encrypt?

Could anyone please give an idiot-proof step by step guide again on how to do this, specifically using the Synology DiskStationManager interface?Sword meaning symbol
Hello, I have the same problem. Now, I have to renew it. To do it, I have deleted the old one but when installing the new one, I have an issue as you can see in attachment. However, I have the configuration as when I have installed the first certificate same ports opened…. Yes you can serve web services of it etc but it is a NAS box and a lot of the challenges people run in to is because of it.
Saying all that the best course of action is to review the article above and if you still need to get a head over to the synology forums and ask for it there. So, my certificate expired a couple of days ago. Clicked to view certificate details and all seems in order. I have done absolutely nothing - I was reading some of the links you guys posted and it seems that even though the certificate is valid for 90 days, there is some sort of auto renewal although I am not sure why and how to check that it was indeed auto-renewed.
Some of the comments also said that the log did not capture the renewal is. Before the certificates expire, DSM will automatically renew such certificates after successful domain validation. Please make sure your Synology NAS and router have port 80 open for certificate renewal. I have the same issue too. May be some files are still somewhere in my NAS and prevent from the renewing of certificate?
Post these things on the synology forum as they should have a better insight on how their client works and how to troubleshoot common errors. Note: the official client is Certbot however other manufacturers and vendors such as webhosts may choose to write their own ACME is an open specification.
For port 80 andI opened it manually using the router admin page instead of using the Synology automatic port forwarding software. This worked better than my initial setup when I used the automatic one.
Not sure if thatll help tho! Similar issues with Synology built in LetsEncrypt client. When I recently tried to add a subdomain, I get the error about port 80 being closed.
After checking my network settings several times to confirm 80 was open, I still failed canyouseeme. DSM must be using a different method to renew certs than to make a new request…???
