(JavaScript) Sign XML to Create P7S

Demonstrates how to sign XML to create a 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();

var cert = new CkCert();
success = cert.LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123");
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;

crypt.HashAlgorithm = "sha256";

// We can sign any type of file, creating a .p7s as output.
// The .p7s contains the signature and also embeds the data of the file that is signed.
var inFile = "qa_data/xml/sample1.xml";
var p7sFile = "qa_output/sample1.xml.p7s";

// Create the CAdES-BES attached signature, which contains the original data.
// Note: Chilkat's function naming is not accurate.  CreateP7M creates a PKCS7 signature where the signed file
// is contained within the signature.  CreateP7S creates a detached PKCS7 signature where the signed file
// is NOT contained within the signature.  We want the data to be contained in the signature, therefore
// we call CreateP7M even though we are naming our output file .p7s.
success = crypt.CreateP7M(inFile,p7sFile);
if (success == false) {
    console.log(crypt.LastErrorText);
    return;
}

// Verify the .p7s file and extract the original file from the .p7s. 
var extractedToFilePath = "qa_output/sample1.xml";
success = crypt.VerifyP7M(p7sFile,extractedToFilePath);
if (success == false) {
    console.log(crypt.LastErrorText);
    return;
}

console.log("Success!");
