Summary: Use Windows PowerShell to discover certificate thumbprints.
How can I use Windows PowerShell to discover the thumbprints of certificates that are installed on my machine?
Interrogate the certificate store, which is exposed as the cert: drive:
Get-ChildItem -Path cert: -Recurse | select Subject, FriendlyName, Thumbprint | Format-List
You will see a lot of entries like this:
Subject : OU=Go Daddy Class 2 Certification Authority, O="The Go Daddy Group, Inc.", C=US
FriendlyName : Go Daddy Class 2 Certification Authority
Thumbprint : 2796BAE63F1801E277261BA0D77770028F20EEE4
Filter the results by using Path or Where-Object to discover the certificate you need.
