/**
|
* Protect document against editing in Word.
|
*
|
* Note: encyption, signing are different concepts. For encryption, use Docx4J.save
|
* with Docx4J.FLAG_SAVE_ENCRYPTED_AGILE. For signing, you need the Enterprise edition.
|
*
|
* WARNING: this doc protect functionality may give a false sense of security, since it only affects
|
* the behaviour of Word's user interface. A mischevious user could still edit the document
|
* in some other program, and subsequent users would *not* be warned it has been tampered with.
|
*
|
* So if you protect the document against editing, you should also sign it. A signature will warn
|
* if the docx has been tampered with (unless the signature is removed entirely, which is easy enough).
|
*
|
* (Encrypting the docx when you
|
* save it doesn't help much in this scenario, since you have to share the password with viewers - there
|
* are no separate passwords for viewing versus editing).
