I didn't say I saw a problem, just expressing surprise. ;)

Anyway, thanks to brontide for digging in and providing helpful info.

I have the same problem :(

This is a WPA-only problem I take it? I use a 64-char code in one of my configured WEP settings.

I found something on wikipedia :)

Security in pre-shared key mode

Pre-shared key mode (PSK, also known as personal mode) is designed for home and small office networks that don't require the complexity of an 802.1X authentication server. Each user must enter a passphrase to access the network. The passphrase may be from 8 to 63 printable ASCII characters or 64 hexadecimal digits (256 bits).[2] If you choose to use the ASCII characters, a hash function reduces it from 504 bits (63 characters * 8 bits/character) to 256 bits (using also the SSID). The passphrase may be stored on the user's computer at their discretion under most operating systems to avoid re-entry. The passphrase must remain stored in the Wi-Fi access point.

So... the solution is to brute-force reverse it to some <=63 char string which hashes to the hex string they gave you, and enter that... :p

It shouldn't be to hard to whip something up with gxmessage and gconftool, but I don't have a WPA net to try it on, so someone else do it.

I vaguely remember an earlier thread about hex vs. ascii. In one of the final postings there was a link to a website (possibly made by one of the posters) which would convert from ascii to hex. And possibly more. sorry I don't have a link to the thread, but searching should do it.

Maybe that would work for WEP, but WPA-PSK uses a secure one way hash function. It should be impossible ( for non NSA folks ) to brute force the SHA1 hash used.

Hah! people besides the NSA have botnets; it's just not economically sane for them to try cracking a single WAP.

unless you're using a passphrase that can be broken with a dictionary attack, hence the recommendation to use a very long (possibly the maximum allowed, i.e. 63 chars) passphrase made up of random characters.
