I'm new, be gentle.

Aircrack-ng gave me hex, how do I convert that to ASCII?

I've cracked my WEP-encrypted key and I know I have a strong password (15 characters including special characters, not a dictionary word, not even English, not a keyboard pattern, etc), but the "KEY FOUND!" that aircrack-ng gives me is only hex, no ASCII translation. How come? How do I convert it to the real phrase I used?

I've used the FAQ on Aircrack-ng's page (faq [Aircrack-ng]) but those don't seem to help, even with "%" in front of each pair of hex characters.

I realize that mathematically, I could have a collision between the hex that aircrack-ng found and my own passphrase, but that's supposed to be really really really unlikely, right?
