Hi I'd like to edit the gpg.conf file in my home directory, I'd like to set the "default key" to a particular key I have. However I don't know what info I'm meant to input into the "default key" fiedl. Currently there is a id in there written: 621CC013. I don't know what this is and how to find a similar type of id for my keys. Could someone please help me with this. Many Thanks Dan
