get webpage content from the command line

[gaetanlord]

Hi

Trying to find a way to get the content of the certificate list  webpage  (system_certmanager.php )

I haven't found any way to find the certificate expiration date from the API and from the XML backup

We issue short expiration dates on our VPN certificate, and I'm looking at a way to find the one close to expiration. I'd like to fetch the page and parse the date. Any idea how to proceed, I'm open to any solution

Regards

Reading it from the backup file should be pretty easy if the data is stored there. Below an example of how to read the expiration date for the self-signed web cert from the backup xml-file. This uses xmllint to parse the xml-file, decodes the <crt> node and passes the result to openssl x509 to display the data

Code Select Expand

xmllint --xpath '/opnsense/cert/crt/text()' config-file.xml | base64 -d | openssl x509 -noout -subject -enddate

Don't have any VPN certificates stored on my own setup, so adjust the xpath for the correct node, and of course the name of the input file.
