Advanced PDF Password Recovery (APDFPR) is a program to decrypt protected Adobe Acrobat PDF files, which have "user" and/or "owner" passwords set, preventing the file from opening or editing, printing, selecting text and graphics etc. With the Standard edition of the program, 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). Professional edition can also recover "User" password using brute-force and dictionary attacks, or instantly from the "Owner" password; also, it supports the "key search" attack to decrypt PDF files with 40-bit encryption redardless the password length, guaranteed. Enterprise edition also includes a new "rainbow attack" subsystem -- it is shipped with a DVD that contains special "Thunder tables" (tm) that allow to decrypt all 40-bit PDF files in just minutes instead of days. Finally, Professional and Enterprise editions are able to clean PDF files from digital signatures, JScript code and form fields.
