As described earlier, the .csr file is an ASCII text file that is saved in the
\SYS directory as: \\sys\request.csr. The private key is also saved in the
\SYS directory with a .der extension as: \\sys\srv_key.der. The procedure
for backing up the private key is described in the next section.
The .csr text file is in the following format:
-----BEGIN CERTIFICATE REQUEST----

-----END CERTIFICATE REQUEST-----
NOTE: When sending the .csr to a Certificate Authority it may be
necessary to cut and paste the text between the “Begin certificate request”
and “End certificate request” delimiters. To do this, open the CSR file in a
text editor such as Notepad.
Backup the Private Key
1. Select the Certificate Management arrow ( ) to display the “Certificate
Management” drop-down menu.
2. Select Backup Private Key… from the drop-down menu.
3. Locate the target directory in which to store the .der file and click Save.
NOTE: Since the private key is unique to each .csr, it's 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 it is necessary 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
certificate request” and “End certificate request” delimiters before sending the file to
the CA.
The time it takes to receive the certificate varies based on how quickly the CA
receives the required documentation.
