' 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.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Pkcs11")
set pkcs11 = Server.CreateObject("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 needing to list 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 = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( pkcs11.LastErrorText) & "</pre>"
    Response.End
End If

' Note: To find public keys, we need a session, but it doesn't necessarily need to be logged-on.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = Server.CreateObject("Chilkat.JsonObject")
json.EmitCompact = 0

success = pkcs11.FindAllKeys("public",json)
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( pkcs11.LastErrorText) & "</pre>"
    Response.End
End If
