Protecting Documents in Aspose.Words for Java

Introduction to Document Protection

Document protection is a vital feature when dealing with sensitive information. Aspose.Words for Java provides robust capabilities to protect your documents from unauthorized access.

Protecting Documents with Passwords

To protect your documents, you can set a password. Only users who know the password will be able to access the document. Let’s see how to do it in code:

Document doc = new Document("Your Directory Path" + "Document.docx");
doc.protect(ProtectionType.ALLOW_ONLY_FORM_FIELDS, "password");

In the code above, we load a Word document and protect it with a password, allowing only form fields to be edited.

Removing Document Protection

If you need to remove the protection from a document, Aspose.Words for Java makes it easy:

Document doc = new Document("Your Directory Path" + "Document.docx");
doc.unprotect();

The unprotect method removes any protection applied to the document, making it accessible without a password.

Checking Document Protection Type

You may want to determine the protection type applied to a document programmatically:

Document doc = new Document("Your Directory Path" + "Document.docx");
int protectionType = doc.getProtectionType();

The getProtectionType method returns an integer representing the protection type applied to the document.
