What this tool can

You can check whether the private key matches the SSL certificate and whether the SSL certificate matches the CSR (Certificate Signing Request).
Compare the SSL certificate, private key, CSR and public key hashes, and check if they match.
The information entered will not remain on the server, so please do not worry about it.

If you use the following OpenSSL command, you can check the pair by yourself.

openssl pkey -in privateKey.key -pubout -outform pem | sha256sum
openssl x509 -in certificate.crt -pubkey -noout -outform pem | sha256sum
openssl req -in CSR.csr -pubkey -noout -outform pem | sha256sum

  • checking the pair if you do not know the pair of SSL certificate and private key or CSR when dealing with multiple SSL certificates.
