SSL certificates expire after one to two years to keep encryption up to date. By renewing annually, authorities ensure you have the latest TLS versions and ciphers. New certificates ensure encryption is up to the latest security standards. It’s difficult for hackers to compromise continually replaced keys.
The Importance of Renewal
To avoid expired certificates, renew them before they expire. Update certificate details where applicable to avoid disruptions. Monitor expiration dates and set up automated renewal to renew on time. If expired, buy and install a new certificate.
Expired certificates are invalid. Users see warnings trying to access your website. Renewal maintains security. After an SSL certificate expires, you will no longer be able to communicate over a secure, encrypted HTTPS connection. This is why it’s important to know the validity period of every SSL certificate your organization uses.
Steps for Renewing SSL Certificates
Many web hosts and registrars automate the process, so you might not have to lift a finger. However, knowing how to renew a certificate manually can be essential if your host doesn’t offer automatic renewals. If your certificate has already expired, you must request a new certificate instead of renewing the existing one. Here’s how to renew your SSL:
-
Set reminders for SSL expiration
Most certificate providers can send email alerts reminding you when your certificate is soon to expire. Enable these email alerts to get direct links for purchasing a renewal certificate. -
Generate a Certificate Signing Request (CSR)
A CSR is a unique, encrypted block of text containing information about your site that the CA needs to issue a new SSL certificate.
Technically, a root CA certificate cannot be renewed once expired. We can only generate a new CA certificate, but when created using the existing key, it can be used to sign existing server certificates.
