Load password-protected documents Leave feedback

The encryption protects data and allows only authorized people to open the file. When a file is encrypted, the password must be specified to open the file. To learn how to identify the encrypted file, please refer to the Check if a file is encrypted page.

To load and render an encrypted document, follow these steps:

Instantiate the HtmlViewOptions (or PngViewOptions, or JpgViewOptions, or PdfViewOptions) object.
Set a password in the LoadOptions.Password property.
Note
If the password is not specified, GroupDocs.Viewer throws PasswordRequiredException.
Call the View method.

The following code snippet shows how to load and render an encrypted document:

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
// ...

// Specify a password.
LoadOptions loadOptions = new LoadOptions();
loadOptions.Password = "123456";
// Render a file.
using (Viewer viewer = new Viewer("encrypted.docx", loadOptions))
{
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
    viewer.View(viewOptions);
}

VB.NET

Imports GroupDocs.Viewer
Imports GroupDocs.Viewer.Options
' ...

Module Program
    Sub Main(args As String())
        ' Specify a password.
        Dim loadOptions As LoadOptions = New LoadOptions()
        loadOptions.Password = "123456"
        ' Render a file.
        Using viewer As Viewer = New Viewer("encrypted.docx", loadOptions)
            Dim viewOptions As HtmlViewOptions = HtmlViewOptions.ForEmbeddedResources()
            viewer.View(viewOptions)
        End Using
    End Sub
End Module
