3.3.1 What about PDF documents protection?
PDF security consists of 2 different passwords - a so-called 'user' password and 'owner' password. The first one can protect the document from opening, the second one can place restrictions to the document, for example print disabling. Used cryptoalgorithms were being improved with PDF developing - up to version 1.4 only 40-bit keys have been used, then the 128-bit ones came, and starting from version 1.6, AES encryption is being added.

However, PDF security system is implemented so that a file with restrictions may be decrypted instantly, irrespective of the password length, even for 128-bit keys. A document with password for opening, using 40-bit key, can be decrypted on a modern computer within a week by using guaranteed decryption, like Office 97/2000 (see q. 3.2.3). To open a document with 128-bit key, only brute force can be used.
