Load password-protected document

The encryption is used to protect data and allow only authorized persons to open the file. When a file is encrypted, the passwords must be specified to open the file. GroupDocs.Viewer supports rendering documents that are protected with a password. To learn how to check if the file is encrypted please refer to How to check if file is encrypted documentation article.

The following are the steps to render password-protected documents.

• Instantiate the LoadOptions object;
• Set password in setPassword(…) property;
• Instantiate the Viewer with created LoadOptions object
• Call view(…) method with parameters that you need.

The following code sample shows how to render password-protected documents.

    LoadOptions loadOptions = new LoadOptions();
    loadOptions.setPassword("123456");

    try (Viewer viewer = new Viewer("sample.docx", loadOptions)) {
        HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
        viewer.view(viewOptions);
    }
