How to get the fingerprint of a base64 encoded pfx certificate in windows powershell

I have a base64 encoded .pfx certificate that was encoded in linux using:
cat $my_pfx_cert | base64 -w 0

In windows Powershell, I'm unable to decode this string and produce a meaningful fingerprint however. Below is is my attempt...

Solution

You're likely messing up the encoding when converting it to a string and writing to file with Out-File, so skip that part entirely - the X509Certificate2 constructor takes a raw byte array as input anyway:

$rawCertBytes = [Convert]::FromBase64String($output)
$certificate = [System.Security.Cryptography.X509Certificates.X509Certificate2]::new($rawCertBytes)

Now that you have a [X509Certificate2] object, either read the thumbprint via the API:

$certificate.Thumbprint

Or, if you want to analyze the certificate file on disk (with openssl for example), export it:

# Create a new file
$certFile = New-Item certificate.cer -ItemType File

# Open a writable file stream
$fileStream = $certFile.OpenWrite()

try {
    # Write cert bytes to disk
    $certBytes = $certificate.Export([System.Security.Cryptography.X509Certificates.X509ContentType]::Cert)
    $fileStream.Write($certBytes, 0, $certBytes.Length)
    $fileStream.Flush($true)
    $fileStream.Close()
}
finally {
    # Clean up open file stream
    $fileStream |ForEach-Object Dispose
}
