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
