Protect the Encryption Key
Inconformancewithyoursecurityplan,trackthelocationofeachUSB
devicecontainingtheexportedkeyorthenameofeachpersonwho
receivedtheemailmessagewiththeexportedkeyfileattached.Alsokeep
trackofthepasswordyouusedwhenyouexportedthekey.
Caution
Make sure you keep a record of the password created when exporting the key. You
must have this password and the encrypted file containing the exported key in
order to import the encryption key back into the library. Without the key password,
you are not able to import the encryption 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.
