Subject: RE: Where's the tool wpapcap2john?

Hi magnum,

thanks for your quick answer! Found the time to download and to install the version mentioned by you below. 

Meanwhile I captured the WPA handshake of the targeted WLAN, so from now on the real works has begun.

May I ask you some additional questions regarding some features of john?

As far as I understood, john is capable to use existing wordlists and use some inbuild or customizable rules to "mangle"
new passphrases which are checked against a password file. Is this correct so far?

Right now I'm using an english and a german dictionary with thousands of entries as input wordlists.

The command

   john --wordlist=dictionaries.lst --rules mypasswd

will use the dictionary wordlists and the inbuild rules in /etc/john/john.conf, correct?

I think I will start with this one and I'll see if I'm successful.

Guess, some social engineering will help as well to expand the dictionaries for example with strange
pet names or nicknames.

I'm so curious to see it all work. Thanks a lot for you guys contributing this mighty tool to us.
