A question on the forum
indicated a problem when using a self signed certificate for testing code signing.
According to the about_signing help file
CREATE A SELF-SIGNED CERTIFICATE
To create a self-signed certificate in use the New-SelfSignedCertificate
cmdlet in the PKI module. This module is introduced in Windows PowerShell
3.0 and is included in Windows 8 and Windows Server 2012. For more
information, see the help topic for the New-SelfSignedCertificate cmdlet.
To create a self-signed certificate in earlier versions of Windows, use
the Certificate Creation tool (MakeCert.exe). This tool is included in
the Microsoft .NET Framework SDK (versions 1.1 and later) and in the
Microsoft Windows SDK.
However the cert produced by New-SelfSifgnedCertificate only appears to function as a SSL self signed cert. It isn’t accepted as a code signing cert.
You can still get the makecert utility for Windows 8.1 from
and Windows 8 from
The makecert utility can be found in
C:\Program Files (x86)\Windows Kits\8.1\bin\x64
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
for the 64 & 32bit versions respectively
While you shouldn’t use self-signed certs for production they are useful for testing. My recommendation is to use the makecert utility rather than the PKI cmdlet
