Backup your private key

We're going to export your private key and store it on your private USB and then we're going to make a paper backup.

Private USB

Change directory cd into your private USB, most likely located at /media/PRIVATE.

Then run sudo gpg2 --export-secret-key -a 2F95015B >> 2F95015B-private.asc replacing 2F95015B in the 2 spots, with your own fingerprint.

 [email protected]:/~$ cd /media/PRIVATE
 [email protected]:/media/PRIVATE$ sudo gpg2 --export-secret-key -a 2F95015B  >>  2F95015B-private.asc

List ls the contents of the directory to ensure it's exported it. Your revocation certificate should be there as well.

 [email protected]:~/media/PRIVATE$ ls
 2F95015B-private.asc  2F9501B-revoke.asc

Paperkey

Generating the paperkey is a similar process. We use a little UNIX feature | the pipe operator, to pipe the output of the first function into the second function, gpg2 into paperkey in this case, then we use >> to save the output of paperkey to a file called 2F95015B-paperkey.txt, make sure to substitute your fingerprint.

 [email protected]:/media/PRIVATE$ sudo gpg2 --export-secret-key 2F95015B | paperkey >>  2F95015B-paperkey.txt
 [sudo] password for amnesia:

After that's made, you can ls the directory to ensure it's been created. Now you'll need to print the 2F95015B-paperkey.txt file. Open up the GUI file explorer, locate the file, and open it with gedit. Then print it.

 [email protected]:/media/PRIVATE$ ls
 2F95015B-paperkey.txt  2F95015B-private.asc   2F9501B-revoke.asc

Store your printed copy in a plastic envelope, as it's likely a few pages.

While you're here you can take the option to print out your revocation certificate and if you want, the ascii amoured version of your private key too. As these are in ascii you will need to manually type them up in order to use them.
