// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Chilkat recommends the following free tool for interactively examining the contents of your smart card
// through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

// Let's first look at our smart card..
// Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:



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

// First we need to acquire a context to the smart card in the reader where it is inserted.
// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
ls_ReaderName = "Alcor Micro USB Smart Card Reader 0"
li_Success = loo_Scmd.AcquireContext(ls_ReaderName)
if li_Success = 0 then
    Write-Debug loo_Scmd.LastErrorText
    destroy loo_Scmd
    return
end if

// If successful, the name of the currently inserted smart card is available:
Write-Debug "Card name: " + loo_Scmd.CardName

// We likely shouldn't need to authenticate with the smart card (use a PIN) to simply get a public key,
// so we can skip the PIN authenticatin step..

// Let's get the key(s) present in Container #7.
// In our case (shown in the image above), there is a private key in the "key exchange" position, but no key in the "signature" position.
loo_Pubkey_sig = create oleobject
// Use "Chilkat_9_5_0.PublicKey" for versions of Chilkat < 10.0.0
li_rc = loo_Pubkey_sig.ConnectToNewObject("Chilkat.PublicKey")

loo_Pubkey_kex = create oleobject
// Use "Chilkat_9_5_0.PublicKey" for versions of Chilkat < 10.0.0
li_rc = loo_Pubkey_kex.ConnectToNewObject("Chilkat.PublicKey")

li_Success = loo_Scmd.GetContainerKeys(7,loo_Pubkey_sig,loo_Pubkey_kex)
if li_Success = 0 then
    Write-Debug loo_Scmd.LastErrorText
    destroy loo_Scmd
    destroy loo_Pubkey_sig
    destroy loo_Pubkey_kex
    return
end if

if loo_Pubkey_sig.Empty = 1 then
    Write-Debug "No signature key is present."
else
    Write-Debug "Signature key:"
    Write-Debug loo_Pubkey_sig.GetPem(1)
end if

if loo_Pubkey_kex.Empty = 1 then
    Write-Debug "No Key Exchange key is present."
else
    Write-Debug "Key Exchange key:"
    Write-Debug loo_Pubkey_kex.GetPem(1)
end if

loo_Scmd.DeleteContext()

Write-Debug "Success."

// Here's the output of the above sample code:

// Card name: IDPrime MD T=0
// No signature key is present.
// Key Exchange key:
// -----BEGIN RSA PUBLIC KEY-----
