Backup the Private Key
1. Before backing up the private key, the control system’s \SYS directory
should be the active directory so that Viewport can locate the file:
On the Viewport command line, go to the \SYS directory by typing “cd
\sys”. To open the directory type “dir”. This will display a list of files in the
\SYS directory, including the CSR (request.csr) and the private key
(srv_key.der).
“\SYS” Directory (PRO2 Shown)
2. Now that \SYS is the active directory, select File Transfer | Generate
Certificate Request | Backup Key. Viewport will automatically locate the
srv_key.der file.
Save DER File
3. Browse to the location where the .der file is to be stored and click Save.
Since the private key is unique to each CSR, it is a good idea to back up the
file to secure media.
Obtaining the Certificate
As described earlier, the exact procedure for obtaining a certificate differs depending
on the CA, but in all cases you have to submit the CSR along with all verifying
information that the CA requires. Here it may be necessary to open the CSR file in a
text editor such as Notepad and copy and paste the text between the “Begin new
certificate request” and “End new certificate request” delimiters before sending the
file to the CA.
The time it takes to receive the certificate will vary based on how quickly the CA
receives the required documentation.
