Shows how to get the SHA256 hash of a certificate. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

$cert = New-Object Chilkat.Cert

# Load a certificate object with a certificate.
# The certificate object could have come from any source,
# or perhaps was obtained from another Chilkat function.
# The source does not matter.  What matters is that we have
# a cert object loaded with the certificate..
$success = $cert.LoadFromFile("qa_data/certs/cert_test123.cer")
if ($success -ne $true) {
    $($cert.LastErrorText)
    exit
}

# Get the binary DER of the certificae, and compute the SHA256 hash:
$bdDer = New-Object Chilkat.BinData
$cert.ExportCertDerBd($bdDer)

# Get the base64 representation of the SHA256 hash.
$certHash = $bdDer.GetHash("sha256","base64")

$("Certificate hash in base64 = " + $certHash)
