Shenzhen, Guangdong -- (SBWIRE) -- 11/04/2009 -- PDF Password Unlocker 4.0 is used to decrypt password-protected Adobe Acrobat PDF documents, including both the "password to open" and "password to modify" which protect the file from opening and modifying respectively. This program not only helps to detect the passwords, decrypts the file and opens the document, but allows you to remove the "password to open" to perform the operations that is restricted even when the document is decrypted, like copying text and graphics out of the documents, modifying the document, adding or modifying text notes, printing, etc. Decrypted file can be opened in any PDF viewer (e.g. Adobe Acrobat Reader) without any restrictions—i.e. with edit/copy/print functions enabled.

Three attacks make it faster in speed and more powerful than ever before. The three attacks, brute-force attack, brute-force with mask attack, and dictionary attack, are crucial to the attack speed. They are designed and targeted to be used for different password cases, ignoring how well the password is set. For example, you use the brute-force attack to find the password with no traces, i.e. you forget it all; you use the brute-force with mask attack to look for the password by offering hints, like any capitals, digits, pond key in the password, etc. Dictionary attack is far flexible and smarter for users. You specify a dictionary with creating a text file listing the possible password character sets for the program to base on, which may double or triple the attack speed in an incredible way.
