Update document password

GroupDocs.Merger allows to update password from password-protected document. The resultant document will have new password.
Here are the steps to update document password:

• Initialize LoadOptions class specifying current password;
• Instantiate Merger object with source document path or InputStream and pass LoadOptions object to it;
• Initialize UpdatePasswordOptions class specifying new document password;
• Call updatePassword method and pass UpdatePasswordOptions object to it;
• Call save method specifying file path to save resultant document.

The following code sample demonstrates how to update document password:

String filePath = "c:\sample.xlsx";
String filePathOut = "c:\output\result.xlsx";

ILoadOptions loadOptions = new LoadOptions("SAMPLE_PASSWORD");
IUpdatePasswordOptions updateOptions = new UpdatePasswordOptions("NEW_SAMPLE_PASSWORD");

Merger merger = new Merger(filePath, loadOptions);        
merger.updatePassword(updateOptions);
merger.save(filePathOut);
