Title
Using PowerShell to Detect Certificate.

Summary

Using PowerShell to Detect Certificate.

Synopsis

These PowerShell commands can be used if you are looking to detect what certificates are installed on a system:
set-executionpolicy unrestricted
set-location cert:\localmachine\ca
get-childitem

The above command should show a list of Certificates installed on the system.
  • The adjustment made in the command below should only return objects with "root" in the subject.
get-childitem | where-object { $_.subject -like "*root*"}
  • The adjustment in the command below will return you a list of friendlynames for certs.
get-childitem | format-table friendlyname
  • ?The adjustment made in the command below should only return objects with 256 in the friendlyname. This can be used to detect certificates that are sha256.
get-childitem | where-object { $_.friendlyname -like "*256*"} | format-table friendlyname
  • Sometimes friendlyname is not populated. Instead of friendlyname you can try IssuerName or SubjectName.
(e.g:) get-childitem | format-table IssuerName

PowerShell commands can be run from a Custom Action in a Basic MSI project. See Additional Information for steps and more information.
