From info found on Kevin's page here.
Simple implementation for eircom netopia routers. Stick in the part of the ssid after the "eircom".
Returns the first key only (the one that uses the "Although your world wonder me, " line)
Disclaimer: Stealing is bad. Don't use this to do anything illegal. In fact, don't use this at all. Bai, s4dd
Check this and this!

Needs to be a valid SSID before it returns output. Don't forget the space between the two blocks of 4 numbers!

Over 1.2m uses! :o (why didn't i put up some google ads ;_;)
