PKCS11 Find Private Key by Label

See more PKCS11 Examples

Demonstrates how to find a private key based on a user-specified label.

Note: This example requires Chilkat v9.5.0.96 or later.

VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

' 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.

set pkcs11 = CreateObject("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 = 0) Then
    outFile.WriteLine(pkcs11.LastErrorText)
    WScript.Quit
End If

' Provide a template to find a PKCS11 object.
set jsonTemplate = CreateObject("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
success = jsonTemplate.UpdateString("class","private_key")
success = jsonTemplate.UpdateString("key_type","rsa")
success = jsonTemplate.UpdateString("label","MySshKey")

privKeyHandle = pkcs11.FindObject(jsonTemplate)
If (privKeyHandle = 0) Then
    outFile.WriteLine(pkcs11.LastErrorText)
    WScript.Quit
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:  
outFile.WriteLine("private key handle: " & privKeyHandle)

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