描述: 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 7.x). 2. It also can be used to decrypt files you know password for. 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). Please note that PDF Password Cracker doesn't work with documents which have user-level passwords (preventing the files from being opened), if both user and owner passwords are unknown; and PDF files protected with any 3rd party security plug-ins such as FileOpen.
