1. First, check if your document has print restrictions or if it has been truly encrypted. The way to distinguish between the two is to see if you need a password to open and view the document.
2. If you don't need a password, congratulations! You can crack it with 99% certainty. Just use Remove Protection, Edit Permissions, and Security Restrictions to unlock it.
3. If you need a password to open the document, check if there is a document password. If there is, use the same software as above to crack it, but select the Find Password function. Cracking the password with this software can take a significant amount of time - it could take minutes or even days.
