Cracx allows you to crack archive passwords of any encryption using 7-zip, WinRAR or a custom command, via Brute Force or Dictionary attack.

Note: You must NOT use this program with files you don't have the rights to extract/open/use them!

Currently, the program requires a current version of either 7-zip or WinRAR to be installed, but you can also use it to bruteforce basically anything that is executably via command-line with custom parameters.
On an i7 CPU, it runs approximately 30 combination tests per second.

Feel free to make suggestions or contribute by implementing features and translating the tool into your native language!

    It's pretty good. Only one problem in here. The password searching is getting slower at a time. Maybe add some Cleaning RAM command each 5 minutes searching to get a stable performance.

    The only 'good' archive cracker for 7-Zip that I've seen. The only thing it lacks is a custom 7-zip executable, one that doesn't kill itself after a failed attempt at unpacking. As that would most likely increase the performance of cracking the password. (Launching executables takes about half a second.)
