PDF Password Cracker v3.1Compare Products
PDF Password Cracker is an utility to remove the security on PDF documents (of course, you should have the right to do it, for example, in case of forgotten user/owner password). Only standard PDF security is supported, neither third-party plug-ins nor e-books. Both protection methods are cracked:
1. Restricted operations on file can be disabled (instantly, any Acrobat version up to 8.x).
2. It also can be used to decrypt files you know password for.

PDF security overview
The standard security provided by PDF consists of two different methods and two different passwords. A PDF document may be protected by password for opening ('user' password) and the document may also specify operations that should be restricted even when the document is decrypted: printing; copying text and graphics out of the document; modifying the document; and adding or modifying text notes and AcroForm fields (using 'owner' password).

PDF Password Cracker Pro v3.2Compare Products
PDF Password Cracker Pro
项目符号 PDF Password Cracker Professional edition allows to search for "owner" and "user" passwords with brute-force and dictionary attacks, effectively optimized for speed (however, don't expect to recover long passwords in a reasonable time with these attacks). In addition, it has Key search attack, which guarantees the decryption (regardless the password length and complexity) of PDF files that use 40-bit encryption (the attack takes about 3-4 days on fast CPU systems).
