As we already went through in part 1 of this series, requesting certificates using Let's Encrypt and certbot is rather easy. Today we're going to look at how you can request certificates with multiple Subject Alternative Names, or SANs for short. A SAN is the domain name embedded in the certificate, for example grumpytechie.net certbot certificates to see your current certificate. If the vHost is correct, use. certbot -d spirit.org -d www.spirit.org --cert-name [nameofyourcertificate] to overwrite the existing certificate. PS: Yep, there is a certificate with only the www version: CN=www.spirit.org 13.08.2019 11.11.2019 expires in 30 days www.spirit.org - 1 entr
Yes, the same certificate can apply to several different names using the Subject Alternative Name (SAN) mechanism. 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 Creating SAN certs is indeed straightforward with all Let's Encrypt clients, but the details depend on which client you used. (For example, with Certbot you should add an additional -d item for each domain that needs to be covered by the cert.) niallireland2017 March 22, 2017, 11:33pm #3 Thanks for the quick response Schoen
When one has a multidomain certificate with many SANs (Subject Alternative Names), there can come a situation where one wants to remove certain SANs from the certificate when renewing (e.g. the removed domain is no longer used - retired, or it has become relevant in another multidomain certificate instead; in both cases, to keep things clean, I want to remove the no longer needed SAN from. Certbot is usually meant to be used to switch an existing HTTP site to work in HTTPS (and, afterward, to continue renewing the site's HTTPS certificates whenever necessary). Some Certbot documentation assumes or recommends that you have a working web site that can already be accessed using HTTP on port 80
Certbot is a free and open-source utility mainly used for managing SSL/TLS certificates from the Let's Encrypt certificate authority. It is available for most UNIX and UNIX-like operating systems, including GNU/Linux, FreeBSD, OpenBSD and OS X. This guide will provide a platform-agnostic introduction to the usage of certbot The Certbot client supports two types of plugins for obtaining and installing certificates: authenticators and installers. Authenticators are plugins used with the certonly command to obtain a certificate Um Ihre Zertifikate mit certbot zu erneuern, können Sie den Unterbefehl renew verwenden. Während der Erneuerung verwendet certbot dieselben Plugins und Optionen wie bei der ursprünglichen Ausgabe.

Certbot allows you to generate certificates directly on the server that hosts your website. In my example, this is not the case. I choose to opt to manual configuration. This requires you to copy and paste commands into another terminal session, which may be on a different computer. We will therefore perform the creation in two steps: The first step is to prove that the domain belongs to you. Certbot can then confirm you actually control resources on the specified domain, and will sign a certificate. DNS Challenge This approach requires you to add specific DNS TXT entry for each domain requested. This is useful when you haven't switched DNS yet, but want to issue a certificate in anticipation (for testing) Mit dem Programm Certbot hat Let's Encrypt eine einfach zu bedienende Möglichkeit geschaffen, um SSL-Zertifikate einzurichten.

Certificate resolvers request certificates for a set of the domain names inferred from routers, with the following logic: If the router has a tls.domains option set, then the certificate resolver uses the main (and optionally sans) option of tls.domains to know the domain names for this router. If no tls.domains option is set , then the certificate resolver uses the router's rule, by checking. Certificate expiry and renewal. Let's Encrypt certificates expire after 3 months, so be sure you enable the auto renewal feature.
