PDF password protection applies encryption to the file itself, so that without the correct password the contents are completely unreadable — even if someone gains access to the file. The 256-bit AES standard used by Docuvory is a symmetric encryption algorithm approved by the US National Institute of Standards and Technology (NIST) and is the same standard used in banking, government communications, and military applications. Once encrypted, the PDF can only be opened in any standard PDF viewer by providing the correct password.
