fAircrack v0.3 is ready! Here is what is different:

> Decrypt tab is now split in to sections for easier navigation.
> Fixed bug where you have to press the enable/disable injection buttons twice for them to work.
> Introduced basic integration with John the Ripper!

I have posted some updated screen-shots so take a look.

Update instructions:
Make sure you install John from the extras-devel repos using the following command as root: "apt-get install john". You will also need to extract the new tar into your FAS directory and overwrite any old files.

John The Ripper:
At the moment, I have only included basic support for John. There are a few limitations. Firstly, at the moment it can only break passkeys that are 8 characters long (90% of WPA keys are). Secondly you can only choose either letter, numbers or both, but no special characters yet.

Please remember that it's about 3.30am here and I have JUST finished it. I don't see any problems but if something isn't working just post here and I will have a look in the morning.

Usage:
To use John just navigate to the Decrypt tab and then click WPA. Now select the cap that you have captured a handshake for, choose your John settings (numbers/letters) then make sure you have highlighted the "John" button above the "Decrypt" button.

Please note that this is more proof of concept than anything else, and please read through the WPA section of the FAQs if you haven't already.

Have fun
