Introduction
------------

This program (Advanced RAR Password Recovery, or simply ARPR)
can be used to recover the lost password for a RAR archive. At
the moment, there is no known method to extract the password
from the compressed file, so the only available methods are
"brute force" and dictionary-based attacks. Here is a brief
list of ARPR's advantages:

- The program has a convenient user interface
- 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)
- 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, Windows 98, Windows NT 4.0 or Windows 2000
- 4 megabytes of RAM
- about 1 megabyte of hard disk space


Known bugs and limitations
--------------------------

- When the files in archive are "stored" (without compression,
  just with encryption) -- the speed might be much lower
  than expected (especially on large files), because decrypting
  the whole file is required.
- RAR 1.x archives are not supported.
