Advanced ARJ Password Recovery 2.0 ========================================== (c) 2000 Elcom Ltd (A.Malyshev, I.Golubev) Contents -------- Introduction Requirements Known bugs and limitations Where to get the latest version Introduction ------------ This program (Advanced ARJ Password Recovery, or simply AAPR) can be used to recover the lost passwords for a ARJ and WinArj archives. At the moment, there is no known method to extract the password from the compressed file, so the only available methods are "brute force", dictionary-based and known-plaintext attacks. Well, there are a lot of programs like this around, but all of them have their own "pros" and "cons". Here is a brief list of AAPR's advantages: - The program has a convenient user interface - The program is very fast: about two million passwords per second (on Pentium II) - Self-extracting archives are supported - The program is customizable: you can set the password length (or length range), the character set to be used to generate the passwords, and a couple of other options - You can select the custom character set for brute-force attack (non-English characters are supported) - Dictionary-based attack is available - The "brute-force with mask" attack is available - The maximum password length is not limited (in registered version) - Very fast known-plaintext attack is available - No special virtual memory requirements - You can interrupt the program at any time, and start from the same point later - The program can work in the background, using the CPU only when it is in idle state The next versions will have much more useful features, of course. Requirements ------------ - Windows 95 (any version), Windows 98, Windows NT 4.0 or Windows 2000 running on Pentium CPU - 4 megabytes of RAM - about 1 megabyte of hard disk space Known bugs and limitations -------------------------- - The program might not work with archives created with ARJ newer than version 2.60. - When files in archive are "stored" (ARJ method 0) or packed with method 4, the performance might be lower than expected, because unpacking the whole file is required.
