PKCS11 Find Specific Certificate on Smart Card or USB Token

See more PKCS11 Examples

This example code shows how to find a particular certificate on a smart card or USB token.

Note: This example requires Chilkat v9.5.0.88 or later.

// or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)

// The FindCert method can find a particular certificate in a number of different ways.
// I'll demonstrate some common ways..

// 1) In many cases you'll be working with a smart card that contains one certificate that is to be used for 
// signing, and it is the certificate that is associated with the private key also stored on the smart card (or USB token).
// There may be other certificates on the card, but these are the issuer certificates in the chain of authentication.
// You're just interested in getting the certificate with the private key.
// You can do it like this:
loo_Cert = create oleobject
li_rc = loo_Cert.ConnectToNewObject("Chilkat.Cert")

// Pass the keyword "privateKey" in the 1st argument, and an empty string in the 2nd arg.
// This returns the 1st certificate that has a private key.
li_Success = loo_Pkcs11.FindCert("privateKey","",loo_Cert)
if li_Success = 1 then
    Write-Debug "Cert with private key: " + loo_Cert.SubjectCN
else
    Write-Debug "No certificates having a private key were found."
end if

// 2) Find a certificate by the Subject Common Name
li_Success = loo_Pkcs11.FindCert("subjectCN","Chil application account (8c9be8e0-5544-4cd0-9062-290fbff353a7)",loo_Cert)
if li_Success = 1 then
    Write-Debug "Found: " + loo_Cert.SubjectCN
else
    Write-Debug "Not found: " + loo_Cert.SubjectCN
end if

// 3) Find a certificate by hex serial number
li_Success = loo_Pkcs11.FindCert("serial","5087bf1feda006af54a02f23a851104948acc26f",loo_Cert)
if li_Success = 1 then
    Write-Debug "Found: " + loo_Cert.SerialNumber
else
    Write-Debug "Not found: " + loo_Cert.SerialNumber
end if

// 4) Find a certificate by hex serial number and Issuer Common Name
li_Success = loo_Pkcs11.FindCert("serial:issuerCN","5087bf1feda006af54a02f23a851104948acc26f:Ibanity Production Third Party Application CA",loo_Cert)
if li_Success = 1 then
    Write-Debug "Found: " + loo_Cert.SubjectCN
else
    Write-Debug "Not found: " + loo_Cert.SubjectCN
end if

// --------------------------------------------------------------------------

// Revert to an unauthenticated session by calling Logout.

    li_Success = loo_Pkcs11.CloseSession()
