Euh ... I don't know.

I set up patatt in octobre when you asked. I guess I generated a key 
with patatt keygen.

I have a [patatt] section in .gitconfig which contains:
	signingkey  = ed25519:xxxxxxxx
	selector = xxxxxxxx (the same value as above)

What should I do now for you to get the key ? I don't even know where 
the key is stored in my computer.

Thanks
Christophe
