    What is this?

    Comparing Aircrack-ng versus coWPAtty, in the time it takes to crack a WPA2 PSK key.
    It shows 4 different cracks, the time taken and speed of the crack (see results).
    > Aircrack-ng (Dictionary)
    > Aircrack-ng & airolib-ng (Pre-computed hashes)
    > coWPAtty (Dictionary)
    > coWPAtty & Genpmk (Pre-computed hashes)


    How does this work?
    To crack WPA/WPA2 PSK you need to capture a ‘Handshake’ . The best way to this packet the attacker needs to disconnect a connected client currently on the network (if the attacker keeps on repeating this part, it will be a DoS to the user).

    Once the key packet has been captured, it is time to start an offline dictionary attack. If the network key is in the dictionary, its just a question of waiting to process the dictionary file.

    From here, the attacker can use that key to decrypt the captured data from before, and now is able to ‘read’ it as well as join the network.

    If there isn't a connected client - you cant do this. If the network key isnt in the dictionary file - you cant do this.

    You can speed the the cracking process by creating pre-calculated hash files (see results - for how much faster!)
