Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.

This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

    Ningún certificado TLS es permanente, pero algunos duran años. Depende del proveedor.

    Certbot tiene post-hooks donde puedes correr scripts arbitrarios. Ahí puedes hacer cosas como convertir el certificado nuevo automágicamente

      --post-hook POST_HOOK
                            Command to be run in a shell after attempting to
                            obtain/renew certificates. Unless --disable-hook-
                            validation is used, the command’s first word must be
                            the absolute pathname of an executable or one found
                            via the PATH environment variable. Can be used to
                            deploy renewed certificates, or to restart any servers
                            that were stopped by --pre-hook. This is only run if
                            an attempt was made to obtain/renew a certificate. If
                            multiple renewed certificates have identical post-
                            hooks, only one will be run. (default: None)
