Certificate Key Matcher
Match Your SSL & Private Key Pairs
If you're renewing your SSL certificate or are managing multiple SSL certificates, you might get confused. Therefore, you must verify which CSR or Private Key belongs to which certificate. You can easily do that on your computer by running 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
