Protecting Word documents

Since version 18.6, GroupDocs.Watermark provides a simplified way of protecting the Word documents with the password. The API allows you to protect as well as unprotect the Word documents. The following protection types are supported:

  • AllowOnlyRevisions: user can only add revision marks to the document.

  • AllowOnlyComments: user can only modify comments in the document.

  • AllowOnlyFormFields: user can only enter data in the form fields in the document.

  • ReadOnly: no changes are allowed to the document.

The protection types are added to the WordProcessingProtectionType enum. Following code samples demonstrate how to protect and unprotect Word documents.

Protecting a document

Following code sample protects a Word document with the password.

WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();                                   
// Constants.InDocumentDocx is an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker(Constants.InDocumentDocx, loadOptions);                          
                                                                                                           
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);                       
                                                                                                           
content.protect(WordProcessingProtectionType.ReadOnly, "7654321");                                         
                                                                                                           
watermarker.save(Constants.OutDocumentDocx);                                                               
                                                                                                           
watermarker.close();                                                                                       

Unprotecting a document

The following code sample shows how to unprotect a Word document regardless of password.

WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();                                   
// Constants.InDocumentDocx is an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker(Constants.InDocumentDocx, loadOptions);                          
                                                                                                           
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);                       
                                                                                                           
content.unprotect();                                                                                       
                                                                                                           
watermarker.save(Constants.OutDocumentDocx);                                                               
                                                                                                           
watermarker.close();
