PDF password
-
Version
10.1.6805
Utility to recover lost passwords to password-
protected PDF files (*.pdf). PDF Password recovers
user and permission passwords only. PDF Password does
not allow to break DRM (Digital Right Management)
system. If user password (also known as password to
open) is either not set or known, it is possible to
remove permission password instantly. Unfortunately,
if a user password is unknown, there is no easy way to
recover the password to a PDF document. Universal
recovery methods, such as Brute Force Attack and
Dictionary Search, must be used. Unfortunately, due to
a nature of an encryption method used in PDF files,
the password search is very slow. 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 user password is
either not set or known).
