Product Description
This program can be used to decrypt protected Adobe Acrobat PDF files, which have 'owner' password set, preventing the file from editing (changing), printing, selecting text and graphics (and copying them into the Clipboard), or adding/changing annotations and form fields (in any combination). Decrypted file can be opened in any PDF viewer without any restrictions. All versions of Adobe Acrobat (including 5.x, which features 128-bit encryption) are supported.
Professional edition also 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 resonable time with these attacks). In addition, it has Key search attack, which guarantees the decryption of PDF 1.3 files (Acrobat 4.x or older) regardless the password length, by trying all possible 40-bit encryption keys (it takes about 3-4 days on modern dual-CPU systems).
