Follow these instructions to generate a certificate signing request (CSR) for your Apache Web server. When you have completed generating your CSR, cut/copy and paste it into the CSR field on the SSL certificate-request page.
Replace yourdomain with the domain name you're securing. For example, if your domain name is coolexample.com, you would type coolexample.key and coolexample.csr.
If you do not want to enter a password for this SSL, you can leave the Passphrase field blank. However, please understand there might be additional risks.
