(VB.NET) 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.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

' 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.

Dim pkcs11 As New 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.
Dim pin As String = "0000"

' Normal user = 1
Dim userType As Integer = 1

' Establish a logged-on user session with the HSM.
Dim success As Boolean = pkcs11.QuickSession(userType,pin)
If (success = False) Then
    Debug.WriteLine(pkcs11.LastErrorText)
    Exit Sub
End If


' Provide a template to find a PKCS11 object.
Dim jsonTemplate As New 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
jsonTemplate.UpdateString("class","private_key")
jsonTemplate.UpdateString("key_type","rsa")
jsonTemplate.UpdateString("label","MySshKey")

Dim privKeyHandle As UInt32 = pkcs11.FindObject(jsonTemplate)
If (privKeyHandle = 0) Then
    Debug.WriteLine(pkcs11.LastErrorText)
    Exit Sub
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:  
Debug.WriteLine("private key handle: " & privKeyHandle)

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