  new aw.Saving.PdfEncryptionDetails("password", '', aw.Saving.PdfPermissions.ModifyAnnotations | aw.Saving.PdfPermissions.DocumentAssembly);

// Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
// to modify how that method converts the document to .PDF.
let saveOptions = new aw.Saving.PdfSaveOptions();
// Enable encryption via the "EncryptionDetails" property.
saveOptions.encryptionDetails = encryptionDetails;

// When we open this document, we will need to provide the password before accessing its contents.
doc.save(base.artifactsDir + "PdfSaveOptions.EncryptionPermissions.pdf", saveOptions);
