PDF Password is a tool to decrypt forgotten passwords to password-protected PDF documents (*.pdf). PDF Password breaks customer user and permission passwords only. PDF Password does not allow to decrypt DRM (Digital Right Management) system. If customer user password is either not set or known, it is possible to reset a permission password. Unfortunately, if a customer user password is unknown, there is no easy way to break the password to a PDF document. Brute Force Attack and Dictionary Search must be used. The brute force speed is usually under one thousand passwords per second even on a top-speed modern PC. The recovery methods used by PDF Password: Brute Force Attack, Dictionary Attack, Smart Force Attack, Password Variation, Reset password (only if customer user password is either not set or known).
