Where is the official ACME v.2 client?


Where is the official ACME v.2 client? What is the download link?


Certbot supports ACME v2.

Also, https://letsencrypt.org/docs/client-options/#acme-v2-compatible-clients .


Which one is official?


Certbot is the ‘officially blessed’ client.


So, there is no offical client.


If you’ve convinced yourself of that, sure, why not. ISRG, the org. that runs Let’s Encrypt, doesn’t build a client, but since Certbot is plastered all over the letsencrypt.org site, there’s probably a straightforward conclusion you could come to on your own.


I have conlusion which is based on the fact that there is no an official client. It is based on the fact that it does not exist. The topic was about this.


There is no official ACME client, but Certbot was once maintained by ISRG/Let’s Encrypt (it is now maintained by the EFF) and it remains our recommended ACME Client, as listed here: https://letsencrypt.org/docs/client-options/


Hello, boulder engineer. I was trying to use the Certbot. But it is said that there is no package for nginx after the command sudo yum install certbot-nginx. After that I tried another method from here: https://certbot.eff.org/lets-encrypt/centos6-nginx but it is also said that “Certbot’s DNS plugins which can be used to automate obtaining a wildcard certificate from Let’s Encrypt’s ACMEv2 server are not available for your OS yet.”

I am not expert in all this staff and the idea of using the Docker seams to be very complicated for me.

Do you have any idea of simplifying the process? I created the request in the help topic here: Error whyle trying to install Cerbot for the Nginx


You might want to try to do a “yum update” now. Granted I’m using CentOS 7 and not CentOS 6, but in the last few hours the v2-compatible client (Certbot v0.22) became available in my CentOS 7 EPEL repository.

If you’re not already using EPEL you can find more info and instructions at https://fedoraproject.org/wiki/EPEL


I am not using epel. My CentOS is 6.9. I was installing CertBot today but it is said by the CertBot engineer that they do not have the auto installation of the Wildcard for the CentOS. You can read his reply here: Error whyle trying to install Cerbot for the Nginx
