Backing up keys
You should probably not use the same key for any extended amount of time, and there’s no reason to since they’re small and simple to generate.
Still, making a backup of your keyring is never a bad idea. To do so, you just need
to copy the entire keyring folder (which is /home/username/CryptocamKeyring
by default or
My Documents\CryptocamKeyring
on Windows) and copy it to your backup location. If you
want to back up (or transfer) specific keys, you can copy the file with that key’s name
inside that folder.
