Wireless encryptions & passwords ..

    Couple of questions about wireless, encryption and passwords ...

    When I choose WEP encryption -> 128bit encryption -> passphrase and then enter my passphrase as "mypassword1234" I then get a list of "keys generated by this passphrase" in the form of "AA BB CC DD EE FF 11 22 33 44 55 66 77".

    Now, when I goto connect to the wireless network from my laptop I'd like to enter "mypassword1234" but it seems I can only enter "AA BB CC DD EE FF 11 22 33 44 55 66 77" to connect.

    What am I missing? Is it down to support on the wireless adapter itself ?

    Thats the way I set up WEP too. I think (not too sure) that it only uses your "passphrase" as a generator for the actual WEP key. If you use WPA you won't have this problem. You get to choose the actual key itself. Plus you'll feel a lot safer knowing that your network is secure. WEP is a very weak form of encryption and is very easily cracked. But then again it might be more than sufficient for you if you don't have any nosey neighbours...

    So, if someone gives me a wireless password in the form of "mypassword1234" they're using WPA encryption? (like many cafes and wifi zones?)

    There's no way to have a password in the form of "mypassword1234" using WEP ?

    I'm not an expert but that has just been my experience with WEP. I didn't really pursue it. I just took what was given to me. On my linksys when i enter in a passphrase i'm given 4 or 5 keys like you described. Maybe if you pick one of those keys and replace it with what you want it might work. However I would imagine that this would not be recommended. Unless your using a device that only supports WEP and cant' support WPA you should really be aiming for the latter.

    Edit: It just occured that if you did replace one of the keys with your passphrase it would most likely need the same amount of characters. As it is this that determines what "bit" encryption your using. WEP only supports 64 and 128 bit afaik. So that would most likely mean 8 and 16 characters respectively. Someone correct me if i'm wrong.

    With WEP:
    - is there an option for passphrase or hex key? Or can both be used together?
    - is the ability to connect to a wireless hotspot which uses a passphrase dependant on the software or hardware you're using?


    I'm not interested in getting into a debate on the benefits of WPA over WEP, but thanks for your thoughts anyhow :)
