# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

$pkcs11 = New-Object Chilkat.Pkcs11

# Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
# (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
$pkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll"

# Establish a logged-on session. (We can typically skip the login by passing an empty PIN if only working with public keys)
# Use your actual PIN here, or an empty string to skip login.
$pin = "0000"
$userType = 1
$success = $pkcs11.QuickSession($userType,$pin)
if ($success -eq $false) {
    $($pkcs11.LastErrorText)
    exit
}

# Get the handle of the public key we wish to export.
# You can find public keys in many different ways.
# This example will search for a public key by label.

# Provide a template to find a PKCS11 object.
$jsonTemplate = New-Object Chilkat.JsonObject

# Find the public key with the label "Belgium eHealth".
$jsonTemplate.UpdateString("class","public_key")
$jsonTemplate.UpdateString("label","Belgium eHealth")

$pubKeyHandle = $pkcs11.FindObject($jsonTemplate)
if ($pubKeyHandle -eq 0) {
    $($pkcs11.LastErrorText)
    exit
}

# Export to a Chilkat public key object.
$pubKey = New-Object Chilkat.PublicKey
$success = $pkcs11.ExportPublicKey($pubKeyHandle,$pubKey)
if ($success -eq $false) {
    $($pkcs11.LastErrorText)
    exit
}

# Get the public key as PKCS8 PEM.
$($pubKey.GetPem($false))
