Can I match a CSR to a certificate as well?
Yes. Fill all three fields and the matcher also compares the CSR with the certificate and with the private key. The CSR field is optional, and you can match a CSR against a private key with no certificate at all.

How do I know if my private key matches my certificate?
Paste both into the tool and read the certificate-to-private-key verdict. A match means the public-key fingerprints are identical; a single differing character means they are not a pair.

Does the Certificate Key Matcher upload my private key?
No. Your files are read and compared inside your browser, and nothing is transmitted. You can disconnect from the internet before running a check and it still works.
