# 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.
# For example:
$pkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll"

# Use your HSM's PIN.
$pin = "0000"

# Normal user = 1
$userType = 1

# Establish a logged-on user session with the HSM.
$success = $pkcs11.QuickSession($userType,$pin)
if ($success -eq $false) {
    $($pkcs11.LastErrorText)
    exit
}

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

# Find an RSA private key with the label "MySshKey".
# Here's an example of how the key was originally imported: 
# PKCS11 Import SSH Key
$jsonTemplate.UpdateString("class","private_key")
$jsonTemplate.UpdateString("key_type","rsa")
$jsonTemplate.UpdateString("label","MySshKey")

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

# The private key handle is only valid during the PKCS11 session.
# If you wish to use the private key in another PKCS11 session,
# you'll first need to find it.  See:  
$("private key handle: " + $privKeyHandle)

# Do whatever you wish with the private key handle...
