Support for XAdES Signature with Node.js via C++

Introduction

Aspose.Cells provides support for signing workbooks with XAdES Signature. For this, the API provides the DigitalSignature class and XAdESType enumeration.

How to Add XAdES Signature for Excel

The following code snippet demonstrates the use of the DigitalSignature class to sign the source workbook.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Source directory
const sourceDir = path.join(__dirname, "data");
// Output directory
const outputDir = path.join(__dirname, "output");

const filePath = path.join(sourceDir, "sourceFile.xlsx");
const workbook = new AsposeCells.Workbook(filePath);
const password = "pfxPassword";

const pfx = path.join(sourceDir, "AsposeDemo.pfx");


const signature = new AsposeCells.DigitalSignature(pfx, "aspose", "testXAdES", new Date());
signature.setXAdESType(AsposeCells.XAdESType.XAdES);
const dsCollection = new AsposeCells.DigitalSignatureCollection();
dsCollection.add(signature);

workbook.setDigitalSignature(dsCollection);

workbook.save(outputDir + "XAdESSignatureSupport_out.xlsx");
