Powershell trick #2 – creating CertificateStore XML


A few weeks ago I wrote about constructing CertificateStore XML by hand. You have to open up the certificate in the browser, and export it as base64 XML, and it's a pain.

Here's a Powershell script that makes it much easier. Just pass it the name of a certificate file on the command line and it will output XML to add the certificate to the ROOT store. Then you can turn the XML into a CAB file, or add it to install XML, or process it in your application.

 

 

# CertificateStore template for adding a ROOT cert
$certAddString = @"
<wap-provisioningdoc>
    <characteristic type="CertificateStore">
        <characteristic type="ROOT">
            <characteristic type="{0}">
                <parm name="EncodedCertificate" value="
                    {1}
                "/>
            </characteristic>
        </characteristic>
    </characteristic>
</wap-provisioningdoc>
"@

# Load in a .CER file from the command line
$cert = get-pfxcertificate $args[0]

# get the thumbprint
$certHash = $cert.GetCertHashString()

# Convert the encoded blob to base64 text
$encodedCertificate = [Convert]::ToBase64String($cert.GetRawCertData())

# print those into our WAP xml template
$outXml = $certAddString -f ($certHash, $encodedCertificate)

# finished - write the XML to the outbound pipeline
write-object $outXml

    Would it be possible for you to explain a little further? Not every monkey can fully understand this new method…

    I added some clarification on why you would want to do this above. If it’s still not making any sense, let me know.
