(JavaScript) PKCS11 Certificate Chain

See more PKCS11 Examples

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

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

// 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.

// You will use the DLL (or shared lib) provided by your smart card vendor, or a DLL compatible with your smart card.
// On Windows, if the DLL is located in C:\Windows\System32, specify only the filename.
// Otherwise provide the full path.

// If the certificates in the chain of authentication were contained on the smart card,
// then Chilkat would already have them (via the FindCert function) and the certs in the chain will be automatically used
// as needed when signing occurs.

// If you have CA certs located elsewhere, such as in .cer files, you can make them available to Chilkat in the following way:

var certVault = new CkXmlCertVault();
// Please review the methods available in the XML certificate vault class.  Different methods exist for adding certificates
// from various sources, such as PEM, PFX, or in-memory sources..
success = certVault.AddCertFile("someDir/caIntermediateCert.cer");
// ...
success = certVault.AddCertFile("someDir/caCert.cer");
// (Your code should check the return value to make sure it succeeded.)

success = cert.UseCertVault(certVault);
if (success == false) {
    console.log(cert.LastErrorText);
    success = pkcs11.CloseSession();
    return;
}

// --------------------------------------------------------------------------
// At this point, we have the cert (and certs in the chain of authentication) to be used for signing.
// The code for using the certificate in creating the digital signature, such as for a PDF, XML, etc., go here...

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

// Revert to an unauthenticated session by calling Logout.
success = pkcs11.Logout();
if (success == false) {
    console.log(pkcs11.LastErrorText);
    success = pkcs11.CloseSession();
    return;
}

// When finished, close the session.
// It is important to close the session (memory leaks will occur if the session is not properly closed).
success = pkcs11.CloseSession();
if (success == false) {
    console.log(pkcs11.LastErrorText);
    return;
}

console.log("Success.");
