Use this tool to verify that the CSR or SSL Certificate and Private Key are made to work with each other. Due to the sensitive nature of this tool, it should only be used in a non-production environment.
Our tool will check whether a Private Key matches an SSL Certificate or Certificate Signing Request. Installation of an SSL Certifiate requires the corresponding Private Key - any mismatch will prevent the SSL Certificate from functioning correctly, resulting in browser errors and pop-up warnings.
