System requirements
-------------------

- Pentium or higher CPU
- 8 megabytes RAM
- Windows 95, Windows 98 or Windows NT operating system
- less than 1 megabyte of hard disk space


Overview
--------

ARCHPR is a program to recover lost or forgotten passwords to
archives (compressed files) of the following types:

- ZIP/PKZip/WinZIP
- ARJ/WinARJ
- RAR/WinRAR (2.x)
- ACE/WinACE (1.x)

At the moment, there is no known method to extract the password
from such compressed files, so the only available methods are
"brute force" and dictionary attacks (for ARJ and ZIP formats,
known-plaintext attack is also available).

The key features of ARCHPR are:

- The program has a convenient user interface
- The program is very fast: for ZIP, brute-force attack speed
  is up to 15 million passwords per second (on Pentium III)
- The program can work with archives containing only one 
  encrypted file (at about the same speed)
- 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 lot 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 (for ZIP and ARJ)
- 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


Registration
