I've been using the Preview App to generate my passwords and to be able to sign virtually. But now what I want to do is to erase them completely, so that nobody can access them.
For example, if I sell my Mac in a hurry, or if someone accesses my Mac, I want to make it impossible to access those signatures.
I don't mean to press the X (cross) that appears after generating the signature; because I think that by pressing that, that signature must be saved somewhere. I don't know. What I'm saying is to eliminate it in a more strict way, forever.
Is it possible to do this? How?

Signatures are stored in a property list file at the following path:
You can remove this file and empty your trash to be sure they're gone. Any security/assurance you need beyond this will require advanced techniques or a complete wipe of your hard drive.
