Advanced Archive Password Recovery can be used to recover lost or forgotten passwords to ZIP (PKZip, WinZip), ARJ/WinARJ, RAR/WinRAR and ACE/WinACE (1.x) archives. 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).
Guaranteed decryption (usually, within the hour) of most WinZip archives (with 5+ encrypted files) is available; it works regardless the password complexity and length .
The program has a convenient user interface .
The program is very fast: on 1GHz CPU, it tests about fifteen million passwords per second (or about a billion passwords per minute ) -- according to independent reviewers and experts, the fastest ZIP cracker in the world!
PKZip 4.0 archives (with digital signatures and deflate64 compression method) are supported .
Known plainext attack is available.
The program can work with archives containing only one encrypted file only (at 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 (there are some practical limitations, though) .
No special virtual memory requirements .
You can interrupt the program at any time, and restart from the same point later .
The program can work in the background , using the CPU only when it is in idle state .
In fact, ARCHPR accumulates all the features of Advanced ZIP Password Recovery and Advanced RAR Password Recovery , can also break password-protected ACE 1.x and ARJ archives, and supports Guaranteed WinZip attack, not available in Advanced ZIP Password Recovery.
