Quote from HeelpBook on September 9, 2018, 4:54 pmTo check the expiration date and time of a Let's Encrypt certificate we can use OpenSSL command on Linux systems:
openssl x509 -noout -dates -in /etc/letsencrypt/live/yourdomain.tld/cert.pem Where "yourdomain.tld" need to be replaced with the actual website already configured with SSL (Let's Encrypt).
Alternatively, we can use the certbot utility as follow:
certbot certificates This command will output every configured SSL certificates enabled using certbot on the system, for example:
Found the following certs:
Certificate Name: example.com
Domains: example.com, www.example.com
Expiry Date: 2017-02-19 19:53:00+00:00 (VALID: 30 days)
Certificate Path: /etc/letsencrypt/live/example.com/fullchain.pem
Private Key Path: /etc/letsencrypt/live/example.com/privkey.pem
