(JavaScript) CAdES BES Detached Signature

Demonstrates how to create a CAdES BES detached signature file (.p7s).

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.

var success = false;

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

var crypt = new CkCrypt2();

// Use a digital certificate and private key from a PFX file (.pfx or .p12).
var pfxPath = "/Users/chilkat/testData/pfx/acme.pfx";
var pfxPassword = "test123";

var cert = new CkCert();
success = cert.LoadPfxFile(pfxPath,pfxPassword);
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

// Tell the crypt component to use this cert.
success = crypt.SetSigningCert(cert);
if (success !== true) {
    console.log(crypt.LastErrorText);
    return;
}

// The CadesEnabled property applies to all methods that create PKCS7 signatures. 
// To create a CAdES-BES signature, set this property equal to true. 
crypt.CadesEnabled = true;

// We can sign any type of file, creating a .p7s as output:
var inFile = "/Users/chilkat/testData/pdf/sample.pdf";
var sigFile = "/Users/chilkat/testData/p7s/sample.p7s";

// Create the detached CAdES-BES signature:
success = crypt.CreateP7S(inFile,sigFile);
if (success == false) {
    console.log(crypt.LastErrorText);
    return;
}

success = crypt.VerifyP7S(inFile,sigFile);
if (success == false) {
    console.log(crypt.LastErrorText);
    return;
}

console.log("Success!");
