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. 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 convert encrypted documents:

• Instantiate the HtmlViewOptions (or PngViewOptions, or JpgViewOptions, or PdfViewOptions) object;
• Set password in LoadOptions.Password property;
• Call View method.

The following code sample shows how to convert encrypted documents:

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

using (Viewer viewer = new Viewer("encrypted.docx", loadOptions))
{
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
    viewer.View(viewOptions);
}
