Certificate Key Matcher

Match your CSR, SSL Certificate and Private Key Pairs

You can check whether a certificate matches a private key, or a CSR matches a certificate on your own computer by using the OpenSSL commands below:

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

Justin Says: "Any mismatch, especially between a private key and an SSL certificate is going to mess you up. You'll probably have to re-issue and that's going to waste a lot of time."
