You can use OpenSSL to create both a private key and your certificate signing request. Digicert has a useful form that will create the command for use in OpenSSL at their site. Enter the Certificate Details and click Generate. On the right side copy the text in the text box, then paste the customized OpenSSL CSR command into your terminal. One of the most versatile SSL tools is OpenSSL which is an open source implementation of the SSL protocol. There are versions of OpenSSL for nearly every platform, including Windows, Linux, and Mac OS X. OpenSSL is commonly used to create the CSR and private key for many different platforms, including Apache.

How do I verify that a private key matches a certificate?
To verify that an RSA private key matches the RSA public key in a certificate you need to i) verify the consistency of the private key and ii) compare the modulus of the public key in the certificate against the modulus of the private key.
To verify the consistency of the RSA private key and to view its modulus:
openssl rsa -modulus -noout -in myserver.key | openssl md5
openssl rsa -check -noout -in myserver.key | openssl md5
RSA Key is ok
If it doesn't say 'RSA key ok', it isn't OK!'
openssl rsa -modulus -noout -in myserver.key | openssl md5
openssl rsa -check -noout -in myserver.key | openssl md5
RSA Key is ok
If it doesn't say 'RSA key ok', it isn't OK!'

To view the modulus of the RSA public key in a certificate:
openssl x509 -modulus -noout -in myserver.crt | openssl md5
openssl x509 -modulus -noout -in myserver.crt | openssl md5

If the first commands shows any errors, or if the modulus of the public key in the certificate and the modulus of the private key do not exactly match, then you're not using the correct private key. You can either create a brand new key and CSR and contact support, or you can do a search for any other private keys on the system and see if they match.

To search for all private keys on your server:
find / -name *.key
If you are unable to find the private key that corresponds to your certificate, you will need a replacement certificate. Please contact support.
find / -name *.key
If you are unable to find the private key that corresponds to your certificate, you will need a replacement certificate. Please contact support.
