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.

• 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

• 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
