https://www.dekut.com/Technology/protect-unprotect-modify-protection-of-word-documents-in-cloud-using-php/ This article explains how PHP developers can easily apply or modify protection on word processing Documents using Aspose Cloud SDK for PHP. When a document is protected, the user can make only limited changes, such as adding annotations, making revisions, or completing a form. Even if a document is protected with a password, Aspose.Words does not require the password to open, modify or remove protection from the document. When you use Aspose.Words to protect a document, you have the option of keeping the existing password or specifying a new password. If you need to make sure the document is Read Morereally protected from changes, consider digitally signing the document. Aspose.Words supports detecting digital signatures for DOC, OOXML and ODT documents. For PHP code samples and other details please visit the blog announcement page. Wed, 18 Jun 2014 04:39:21 UTC en
