Decrypt protected Adobe Acrobat PDF files that have user and/or owner passwords set, preventing the file from opening or editing, printing, selecting text and graphics etc. If only owner password is set, password recovery is not needed at all, but the file is being decrypted instantly (so all restrictions are being removed). User password can be recovered using brute-force and dictionary attacks; also, the program supports key attack that allows to decrypt PDF 1.3 (Acrobat 4.x) files regardless the password length, guaranteed - that takes only 4-5 days on modern dual-CPU systems.
