Palo Alto Networks Knowledgebase: How to Generate a New Self-Signed SSL Certificate
How to Generate a New Self-Signed SSL Certificate
Created On 02/07/19 23:58 PM - Last Updated 02/07/19 23:58 PM
If you do not want to load your own certificate into the device or use the default self-signed certificate, a new self-signed certificate can be generated through the web interface or CLI.
This new self-signed certificate can be used for SSL Decryption or for a GlobalProtect portal or Gateway Certificates.
1. From the WebGUI, navigate to Device > Certificates.
2. Click Generate at the bottom of the screen.
3. Enter the desired details for the certificate. The details entered here are what users see if they view the CA certificate for an encrypted session using the browser. Note: If you would like the certificate to be valid for longer than 365 days (1 year), then please change the "Expiration (days) from 365 to a larger value before creating the certificate.

4. On the Generate Certificate window, click Generate:
Certificate successfully generated
5. To verify that the certificate was created properly, click on the newly generated certificate.
Note: If using this certificate for SSL Decryption, please check "Forward Trust Certificate" and "Forward Untrust Certificate". To delete or remove the certificate, uncheck both options, otherwise an error is generated.
Enable Forward Trust and Untrust
6. Commit the changes. When the commit operation completes, the Self-Signed CA certificate isinstalled.
From the CLI, to create a new self-signed certificate, run the following command, <all on one line>(PAN-OS 6.1 only)
> request certificate self-signed country-code US email firstname.lastname@example.org locality Alviso state CA organization “Palo Alto Networks” organization-unit “Session inspected by policy” nbits 1024 name “SSL Inspection” passphrase bubba for-use-by ssl-decryption
For PAN-OS 7.0 and after, a very simple self signed certificate can be created with this command:
> request certificate generate name "Firewall-a" certificate-name "ssl test"
You can always use the <tab> or "?" when in the CLI to see what the next commands can be.
