Import an SSH Key to an HSM using PKCS11

See more PKCS11 Examples

Demonstrates how to import an SSH private key to an HSM (smartcard or token).

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

' Create a PKCS11 template for importing the SSH key.
set jsonTemplate = CreateObject("Chilkat.JsonObject")

' Indicate the key is to be stored on the token (i.e. it is not a session-only key)
success = jsonTemplate.UpdateBool("token",1)
' The key should have the ability to sign
success = jsonTemplate.UpdateBool("sign",1)

' Let's provide a few attributes to help us find the this key at a later time.
' See SSH Public-Key Authentication using an HSM

' The ID is byte data, so it should be base64 or hex.
' Specify "id" if passing base64 data, "id_hex" for hexidecimal, or "id_ascii" for directly copying the ascii bytes of the string.
' You can provide any ID of your choice.  It is optional.
success = jsonTemplate.UpdateString("id_hex","0A0B0C0D01020304")

' Optionally specify a label.
success = jsonTemplate.UpdateString("label","MySshKey")

' Load the SSH key to be imported to the HSM (smartcard or token)
set sshKey = CreateObject("Chilkat.SshKey")

success = sshKey.FromPuttyPrivateKey(ppkContents)
If (success = 0) Then
    outFile.WriteLine(sshKey.LastErrorText)
    WScript.Quit
End If

' Import the SSH private key onto the HSM.
' The PKCS11 handle to the imported private key is returned.
' A 0 is returned on failure.
privKeyHandle = pkcs11.ImportSshKey(sshKey,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  SSH Public-Key Authentication using a Smartcard
outFile.WriteLine("private key handle: " & privKeyHandle)

outFile.WriteLine("Successfully imported the SSH key onto the HSM.")
