Alpha Five Application Server CSR Creation
Click the long button at the bottom of the tab with the label 'Generate a Certificate Signing Request.'
Most of the requested information will general company information (usually for your corporate headquarters, as opposed to your current location or the location of the server where you are working), but remember that your country code is a 2-digit code, not the entire country name.
Your common name is the fully-qualified domain name that your certificate will be issued to (e.g., www.example.com or mail.example.com).
This process will generate an encrypted text file (CSR) that you will send to COMODO to request your certificate and an encryped private key. Make sure to hold on to your key file, and send the CSR along with your certificate request to your CA.
Once you have that certificate back (this process can take anywhere from 5 minutes to several hours), you can proceed to the next step.
Installing SSL on Alpha Five
Before you can assign a certificate chain file, check to see if you were provided with multiple intermediate certificate files (COMODOCA.crt and COMODOCA2.crt), if you were, you will need to combine both of the provided intermediate certificates into one file (often called a .pem file) before continuing.
To do this, go ahead and open both files in a text editor and paste the entire body of the CA2 file immediately below the text of the first. Save the combined file as COMODO.pem and continue to the next step.
