Why Check Certificate-Key Match?

When setting up SSL/TLS on a web server, you need both a certificate and its corresponding private key. If they don't match, the SSL/TLS connection will fail.

Common scenarios:

  • Verifying certificate and key files before server installation
  • Troubleshooting SSL/TLS configuration issues
  • Confirming you have the correct key after certificate renewal
  • Validating certificate-key pairs from different sources
