Hi, Yoy sent me 2-3 warning emails about my renew my certification. Can you explain to me why I have to renew my certification ? My certification is valid from 23-10-17 to 21-01-18.
Please check the attached file.
Thanks in advance.
Below your email :
Your certificate (or certificates) for the names listed below will expire in
0 days (on 16 Nov 17 11:13 +0000). Please make sure to renew
your certificate before then, or visitors to your website will encounter errors.
For any questions or support, please visit https://community.letsencrypt.org/.
Unfortunately, we can’t provide support by email.
For details about when we send these emails, please visit
https://letsencrypt.org/docs/expiration-emails/. In particular, note
that this reminder email is still sent if you’ve obtained a slightly
different certificate by adding or removing names. If you’ve replaced
this certificate with a newer one that covers more or fewer names than
the list above, you may be able to ignore this message.

Because there have been 3 certificates issued (you are only looking at the last one).
and the first two are now going to expire.
The system has no way of knowing which certs you are using and which you are no longer using.
If you are no longer using those other two certs, you can ignore the emails.
Hi, thank you very for the response.
I have some questions.
First, please tell me if I want to know which certs I use, I have to ask my web provider ?
Second, If I have to renew the certs, how I will do it ?
Third, do you know the costs of all three and how much each cert ?
Thanks in advance.
The old certificates were missing the
www. form of your website. Your newer ones are correct. You can safely ignore this e-mail.
Your hosting provider typically automatically takes care of this for you, and they seem to have already done so.
Let's Encrypt provides certificates for free!
They do accept donations if you want to lend your support.
Really I appreciate your quick response.
Just as a supplement to what @Patches has said, you can always tell what certificates are in use on your site from within your browser. Each browser has a slightly different way of viewing the certificate presented by your current site.
For example, in Firefox you can click on the padlock icon, then the right arrow, then More Information, then View Certificate.
Currently in Chrome and Chromium the option has been made harder to find; you can see it by pressing F12 (for developer tools), then clicking Security, then View Certificate.
When you view the certificate, you will see the technical details including when the certificate was issued, by which certificate authority, which domain names it covers, and when it expires. It takes some practice to get used to understanding all of the certificate contents because a very large amount of information is presented within the various parts of the certificate. Nonetheless, you can definitely check the certificate for yourself when visiting your own site or other people's sites. The information that you see in the browser this way is the same information that the browser itself used when deciding whether the certificate was valid!
Since @Patches says that your site appears to be OK and your provider appears to have renewed the certificate already, you do not need to do this any of this for yourself at this time, but you can if you'd like to learn more about certificates and digital certification.
