This is a simple but sophisticated open source password recovery tool for M$ Windows, it can effectively 'crack' any password protected archive that can be decompressed by 7zip given enough time and resources. It can also bruteforce MD2, MD5, SHA-1 and SHA-2 hashes (SHA-256, SHA-384, SHA-512), CRC16, CRC32, CRC64 and Adler32 hashed passwords for both Windows, and Linux. It requires java 7u4 and above, and 7-zip v9.20 and up for archive recovery. Keeping these above applications up to date ensures peak performance.

if you have any ideas, bugs, tips/improvements and/or suggestions please dont hesitate to contact me


Known Bugs(v1.09):
-although md2 was selceted by default for hash recovery if you did not slected another value and reselect md2 it would use md5 by default

    I am using a Win7-32bit desktop and 7z version 16. Created a dummy 7z file with the password 123 in the installation folder. Executed jpassrecovery.jar file, in the gui I browsed to the dummy 7z file, for options, I picked 0-9 only and min as 1 and max as 4, after 11110 tries taking 7 minutes, it couldn't even crack a simple password as 123!! I noticed Mr. Krouk was more busy and preoccupied with writing a useless super long copyright file and a readme file with no usage insturctions but pointless release notes! The GUI could use some aesthetic improvement such as the right border not being flushed with the text.

    It would be excellent if you could introduce a feature of 'include these letters only" instead of just exclude. Also if there is a possibility to try combinations involving a certain phrase, this software would be unbeatable! For example, I have a phrase "password" and I want the software to check all combinations of 9 letter phrases tested based on the starting criteria (eg. "numbers alone" should test 1password, p1assword, pa1ssword, pas1sword etc with all possibilities from 0-9). This could speed up a process of recovering passwords with partial matches.

    It is unbelievable slow in finding *.zip passwords. About 50 passwords per second on a 2 GHz Dualcore.

    You work in nice environment, but... (may be I do something wrong) ... I Tried to decrypt the String 900150983cd24fb0d6963f7d28e17f72 I Know that MD5(abc) = 900150983cd24fb0d6963f7d28e17f72 (You can try to encrypt or decrypt this on many sites) The program failed to find the solution
