支持 XAdES 签名

Aspose.Cells 提供支持使用 XAdES 签名对工作簿进行签名。为此，API 提供电子签名类和XAdES类型枚举。

下面的代码片段演示了使用电子签名类签署资源工作簿。

示例代码

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
//Source directory
string sourceDir = RunExamples.Get_SourceDirectory();

//Output directory
string outputDir = RunExamples.Get_OutputDirectory();

Workbook workbook = new Workbook(sourceDir + "sourceFile.xlsx");
string password = "pfxPassword";
string pfx = "pfxFile";

DigitalSignature signature = new DigitalSignature(File.ReadAllBytes(pfx), password, "testXAdES", DateTime.Now);

signature.XAdESType = XAdESType.XAdES;
DigitalSignatureCollection dsCollection = new DigitalSignatureCollection();
dsCollection.Add(signature);

workbook.SetDigitalSignature(dsCollection);

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