I am using Windows 7
, and want to run signed scripts from Powershell
, the security-settings
of Powershell are set to "all-signed"
, and my scripts are signed with a valid certificate
from my company. I have also added the .pfx-file
to my local certificate store (right-clicked the pfx-file and installed)
.
However, when I start a signed script, I get a message that says:
"Do you want to run software from this untrusted publisher?
File Z:\Powershell Signed Scripts\signed.ps1 is published by CN=[MyCompanyName] and is not trusted on your system. Only run scripts from
trusted publishers.
[V] Never run [D] Do not run [R] Run once [A] Always run [?] Help
(default is "D"):"
Since I want to automatically call these scripts on my systems, I would like to add my imported certificate to the trusted list on my system, so that I do not get a message anymore when I run a signed script for the first time. How can I make my certificate a trusted one?
How to trust a certificate in Windows Powershell
Indeed, you can do this without any mmc :)
First, check the location of your personal certificate named for example "Power" :
Get-ChildItem -Recurse cert:\CurrentUser\ |where {$_ -Match "Power"} | Select PSParentPath,Subject,Issuer,HasPrivateKey |ft -AutoSize
(This one should be empty:)
gci cert:\CurrentUser\TrustedPublisher
Build the command with the path to your certificate:
$cert = Get-ChildItem Certificate::CurrentUser\My\ABLALAH
Next work on certificate store (Here I work on two certificate store : user & computer)
$store = New-Object
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store "TrustedPublisher","LocalMachine"
$store.Open("ReadWrite")
$store.Add($cert)
$store.Close()
Check, you should find your certificate :
ls cert:\CurrentUser\TrustedPublisher
