支持使用Node.js通过C++进行XAdES签名

介绍

Aspose.Cells支持使用XAdES签名对工作簿进行签名。为此，API提供了DigitalSignature类和XAdESType枚举类型。

如何为Excel添加XAdES签名

下列代码片段演示了使用 DigitalSignature 类对源文件工作簿进行签名。

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");
