    just add the -w option on the end of your command and specify a dictionary after it for example: root@bt:~# aircrack-ng wep-01.cap -w /pentest/passwords/wordlists/darkc0de.lst

    Make sure you include your real password in that wordlist.

    Yes if it's WEP, No if it's WPA!

    You can use previously hashed passwords that speed-up the checking process but that will still require the passphrase to be in your list to check against the handshake.

    This is where social enginerring comes in, people can't remember passphrases and so use what is easily rememberd for them like thier dogs name or birth date etc. If you have a dictionary of thousands of words inc many commonly used passphrases then anyone who doesn't use a well made passphrase will be vunerable so this is a lesson where you can use a strong passphrase on your own system and then add it to your dictionary to test the function of passphrase cracking.

    You have two differnt file types from the two posts you have made, the 14th of june has a .cap file and the latest has a .ivs file.

    using --ivs will only write initialisation vectors and connot be used for WPA handshake cracking! You will not capture a handshake with this option.

    so run airodump-ng, in monitor mode, on the correct channel, with a .cap save file, when a WPA client connects to the network.

    simply connect a wireless client to your access point while the above is running and you will get a handshake to use with aircrack.

    if you need to you can DeAuth a connected client with Aireplay-ng to get it to re-connect and capture the handshake then.

    you must use the .cap file which captures the handshake and the passphrase must be in the dictionary you use or it wont work.

    You're welcome, you can also try another dictionary that your password may be in.
