PDF Password is a tool to recover lost or forgotten passwords to password-protected PDF files (*.pdf). PDF Password recovers user and permission passwords only. PDF Password does not allow to decrypt DRM (Digital Right Management) system. If user password (also known as password to open) is either not set or known, decryption is being done instantly.
Unfortunately, if a user password is unknown, there is no easy way to decrypt the password to a PDF document. Brute Force Attack and Dictionary Search must be used. Due to a nature of an encryption method used in PDF files, the password search is very slow. 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).
