On this page we describe how to download and run CertAlert for the first time. If you have any questions at all about running CertAlert please email support@redkestrel.co.uk and we will get CertAlert up and running for you in no time. So please don't hesitate to contact us, we love hearing from our users.

Step 1: Unzip the file you downloaded

Unzip the downloaded file (e.g., the downloaded file certalert-2014-05-11.zip) into its own folder. The easiest way to do this is to right-click on the file and then choose Extract All...

Step 2: Open a command window in the folder you extracted CertAlert to

From Windows explorer, move your cursor over the target folder (e.g., certalert-2014-05-11), then shift-right-click and pick the “open command window here” option from the pop-up

Step 3: Run CertAlert

At the command prompt, type CertAlert and press return. CertAlert will check a list of public servers (see the serverlist.txt file).

Note that unless you have a CertCentre account and have configured CertAlert to use it, your results will not be sent to CertCentre.

What Next?

You can try many things, here are just a few in no particular order:
  • Look at the reports created CertAlertReport.csv and CertAlertReport.pdf
  • Change the servers to be checked in the serverlist.txt file
  • Set an IP range to check in the CertAlert.exe.config file
