Protect, Unprotect, Modify Protection of Word Documents in Cloud Using PHP

Microsoft Word password protection is a security feature used to protect documents with a user provided password. Most people use Microsoft Word but sometimes you don’t want everyone to be able to read or modify your documents. There are two options for securing your Word files: either set a password to open the document, or set a password to stop anyone from modifying the document. 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 really protected from changes, consider digitally signing the document. Aspose.Words supports detecting digital signatures for DOC, OOXML and ODT documents.
