Caution
Make sure that you export a copy of the existing key before you delete it. You need
a copy of the exported key and its password to import the key back into the library
and restore data that was encrypted with the key.
Important
Backup files of the library configuration include any encryption keys that were
stored in the library at the time the file was created.
