thanks for the reply Rodrigo, What i am looking for is " to capture from any backup.conf or someway (without login in device and run commands ).. i have the backup file and but i dont have those certificate details there...

You can't find much details on the conf file. The conf file will have the cert details and those cert details will have references to other files like cache-path and source-path. You would need those directories backup to confirm what you are looking.
