Advanced ZIP Password Recovery (or simply AZPR) is a program recover (break) lost or forgotten passwords for a ZIP/PKZip/WinZip archives. Unfortunately, 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. Here is a Brief list of AZPR's advantages:
- The program has a convenient user interface
- The program is very fast: brute-force attack speed is up to fifteen million passwords per second on Modern CPUs like Pentium 4 (Prescott)
- Very fast and effective known plaintext attack is available
- The program can work with archives containing only one encrypted file
- 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
- No special virtual memory requirements
- You can interrupt the program at any time, and resume from the same point later
- The program can work in the background, using the CPU only when it is in idle state
Version 4.0 has improved user interface, digitally-signed setup program, and has much faster brute-force attacks (the improvement is 10%-15% on AMD Athlon, PII/PIII and P4 Prescott, and up to 45% on P4 Northwood).
