//  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.

//  Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
//  For example:
loo_Pkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll"

//  Use your HSM's PIN.
ls_Pin = "0000"

//  Normal user = 1
li_UserType = 1

//  Establish a logged-on user session with the HSM.

    destroy loo_Pkcs11

end if

//  Provide a template to find a PKCS11 object.
loo_JsonTemplate = create oleobject
li_rc = loo_JsonTemplate.ConnectToNewObject("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
loo_JsonTemplate.UpdateString("class","private_key")
loo_JsonTemplate.UpdateString("key_type","rsa")
loo_JsonTemplate.UpdateString("label","MySshKey")

if li_PrivKeyHandle = 0 then
    Write-Debug loo_Pkcs11.LastErrorText
    destroy loo_Pkcs11
    destroy loo_JsonTemplate
    return
end if

//  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:  
Write-Debug "private key handle: " + string(li_PrivKeyHandle)

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