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.

// 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.

loo_Pkcs11 = create oleobject
// Use "Chilkat_9_5_0.Pkcs11" for versions of Chilkat < 10.0.0
li_rc = loo_Pkcs11.ConnectToNewObject("Chilkat.Pkcs11")
if li_rc < 0 then
    destroy loo_Pkcs11
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// 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.
li_Success = loo_Pkcs11.QuickSession(li_UserType,ls_Pin)
if li_Success = 0 then
    Write-Debug loo_Pkcs11.LastErrorText
    destroy loo_Pkcs11
    return
end if

// Provide a template to find a PKCS11 object.
loo_JsonTemplate = create oleobject
// Use "Chilkat_9_5_0.JsonObject" for versions of Chilkat < 10.0.0
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")

li_PrivKeyHandle = loo_Pkcs11.FindObject(loo_JsonTemplate)
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...
// ...
