Hi I'm very new to powershell , i need to fetch only issued certificates from CA server and want to export all issued certificates to csv file by using powershell but unable to find the exact command , any help would be appreciated.
i'm using this command to fetch issued certificates, but getting all certificates, how to filter only issued certificates?
certutil -view -out "RequestID,RequesterName,RequestType,NotAfter,CommonName,CertificateTemplate,SerialNumber"
I'd recommend looking into using the PKITools module as this module includes the ability to retrieve issued certificates with ease.
You should be able to install the module by issuing the following command:
Install-Module -Name PKITools
Once the module has been installed, it should be as simple as running the below (without Format-Table if you want to work with the returned data):
Get-IssuedCertificate | Format-Table
This will give you output similar to the below:

The command I'm using that is working perfectly for the "Trusted Root Certification Authorities\Certificates is:
$file = (Get-Childitem -Path "D:/Root CA 2.cer")
$file = Import-Certificate -CertStoreLocation cert:\LocalMachine\Root
When it comes to the 6 different certs that need to be imported to the "Trusted Root Certification Authorities" this command works perfectly. Root CA 2, 3, 4, 5, and the two different ECA Root's 2 and 4 all are placed in their location. However, when it comes to the CCEB Interoperability cert, this command also places it in the "Trusted Root Certification Authorities". The CCEB Cert is supposed to be located in the "Untrusted Certificates" location. What confuses me most is that when you use the MMC console and right click import and choose this file, it automatically knows that it's supposed to be in the "Untrusted" location. I thought that the Powershell command would produce the same result, but it doesn't. It keeps placing it in the wrong location. I'm brand new to Powershell and can't find any discussion on this topic. Please help and thank you in advance.
Powershell can use cert:\ paths to browse the certificate store like a file system. Check out the about_Certificate_provider page for more details. Each cert store's name is a little different from what you see in the MMC though.
cert:\LocalMachine\Root is the "Trusted Root Certification Authorities" store, so any certificates you import are placed there when you specify -CertStoreLocation that way
"Untrusted Certificates" is named Disallowed, so you can import like so:
Get-Item "D:\folder\BadCerts.sst" |
Import-Certificate -CertStoreLocation "Cert:\LocalMachine\Disallowed"
Powershell can't easily display the certificate trust list (CTL) in the untrusted certs store, but can import just fine
Since I am issuing certificates for my employees, I need to have a data table, namely subject CN, NotBefore, NotAfter. I tried to write a bat file using certutil as well as PS scripts from stackoverflow but never succeeded. There are too many certificates, I can't manually check each one. How can I get the name and expiration metrics from all the certificates that are in the folder? Thank you in advance for your response.
We have a PowerShell script written years ago by someone who has moved on, to sign our ClickOnce deployments. This has worked well, until recently when the certificate expired. I'm tasked with updating the PowerShell script to incorporate the new signing certificate we recently purchased.
I put the new certificate into the Certificate store, per the instructions from the previous maintainer. I've made modifications to the PowerShell script, fixing other bugs as they've come along, but I'm at a place where I don't know how to relate the details of the certificate with the parameters for SignTool.exe. Looking at the properties of the certificate, from the Details view, I see the following relevant values:
Signature algorithm: sha384RSA
Signature hash algorithm: sha384
Thumbprint algorithm: sha1
Looking at Microsoft's SignTool documentation page for the sign command I see values used by the PowerShell such as /td and /fd, but I don't know which relates to the values displayed in the properties for the certificate. Also, I'm not certain that I need the thumbprint algorithm. According to the Microsoft page I referenced it should be used if working with multiple certificates, which the PowerShell script is not.
Here is what is currently in the PowerShell script for signing the ClickOnce app:
Get-AuthenticodeSignature *.exe,*.dll | ? Status -eq NotSigned | % Path | %{&$signtool sign /tr $timestamp /td sha384 /fd sha384 $hash $_ }
That now gives me an error of, "##[error]SignTool Error: No certificates were found that met all the given criteria."
I have a digital certificate that I'm using for a specific task. I need to export the details of the certificate such as the serial number and issuer to a csv file that is already on my computer using PowerShell. Please keep in mind this is a digital certificate that is not installed on my computer but was sent to me and I downloaded it.
you can get the certificate details using the command Get-PfxCertificate as follow
$certpath = 'D:\cert.cer'
Get-PfxCertificate -FilePath $certpath | Export-Csv .\cert.csv -NoTypeInformation

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 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
Sounds like you need to verify that the script is signed properly and that you have the correct certificate installed in the correct certificate store.
Use the Get-AuthenticodeSignature cmdlet to get information about the signed script.
Also review Scott's guide for signing certificates.
