If your SSL certificate expires, it's crucial to renew or replace it promptly to maintain secure communication between your website and users' browsers. An expired SSL certificate can lead to security warnings and potential loss of trust from visitors.
Here's what you should do:
Renewal: Check if your SSL certificate is eligible for renewal. Many certificate authorities offer automated renewal services. Ensure you have an active account with the issuer and follow their instructions for renewal.
Example: If you purchased an SSL certificate from a provider, log into your account on their website and look for the renewal option.
Replacement: If the certificate cannot be renewed (e.g., due to changes in domain ownership or certificate type), you'll need to purchase a new one. Ensure the new certificate matches your domain and server configuration.
Example: If your current certificate is a Domain Validation (DV) certificate and you need a more robust option, consider purchasing an Organization Validation (OV) or Extended Validation (EV) certificate.
Update Server Configuration: Once you have a new or renewed certificate, update your server configuration to use the new certificate files. This typically involves replacing the old certificate and private key files with the new ones.
Example: For an Apache server, you would update the SSLCertificateFile and SSLCertificateKeyFile directives in your configuration file.
Test: After updating the certificate, thoroughly test your website to ensure that the new SSL certificate is working correctly and that there are no issues with secure connections.
Example: Use online SSL checker tools to verify that your certificate is correctly installed and trusted by browsers.
Monitor: Set up monitoring to alert you in advance of future certificate expirations. This helps prevent any unexpected downtime or security warnings.
Example: Use a certificate management tool that provides alerts and automated renewal options.
