Sign document with XML Advanced Electronic Signature Leave feedback

Note

XML Advanced Electronic Signature feature is supported only for Spreadsheet documents

GroupDocs.Signature provides DigitalSignOptions class to specify different amount of settings for Digital signature. One of these settings is the XAdES type, set with setXAdESType to a value of the XAdESType class

Here are the steps to add XML Advanced Electronic Signature with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path as a constructor parameter.
• Instantiate the DigitalSignOptions object with required certificate and its password.
• Call setXAdESType with the value XAdESType.XAdES.
• Call sign method of Signature class instance and pass DigitalSignOptions to it.
• Analyze SignResult result to check newly created signatures if needed.

This example shows how to add Digital signature to document.

Signature signature = new Signature("sample.xlsx");
try
{
    DigitalSignOptions options = new DigitalSignOptions("certificate.pfx");
    // set XAdES type
    options.setXAdESType(XAdESType.XAdES);
    // certificate password
    options.setPassword("1234567890");
    // digital certificate details
    options.setReason("Sign");
    options.setContact("JohnSmith");
    options.setLocation("Office1");

    SignResult signResult = signature.sign(outputFilePath, options);
    System.out.println("Source document was signed successfully with "
            + signResult.getSucceeded().size() + " signature(s). File saved at " + outputFilePath + ".");
}
finally
{
    signature.dispose();
}
