I can't find the debug.keystore file

I'm having an error with Eclipse and Android's SDK. apparently, it comes from the fact that my certificate expired. So I googled the error and I found that I have to remove the ~/.android/debug.keystore file. The thing is I can't find this file. It's not in my SDK.

Can someone help me with this ?

Edit: I work on Mac.

Open Eclipse Preferences, then navigate to Android > Build. There you'll see a field that tells the location of your debug keystore.

On Linux / OSX use your favorite terminal and type rm ~/.android/debug.keystore to remove the debug keystore.

You can create a new keystore after that by following these steps.
