Tools like Foundstone's Google-hacking program, SiteDigger, require a valid Google API License Key to work. I have had one in the past and played with SiteDigger without any problem.

Last week though, I tried to get a new one and I can't find where to get the license key on the Google site any more. All of my searches end up pointing me to http://www.google.com/apis, but there are a wide variety of API's available there- none of which says "web services".

I did manage to get a couple keys from there, but neither worked. I tried both SiteDigger and Wikto and both said that my Google API license key is invalid.

So, the question is WHERE DO YOU GET A VALID GOOGLE API LICENSE KEY???
