Encryption key management
To manage the encryption key settings, log into the NAS as an administrator and go to
"Storage Manager" > "STORAGE" > "Storage Space". Double click a volume to bring up the
Volume Management page and click "Actions" > "Encryption".
There are three options to manage the encryption key:
 Change the encryption key: Enter your old encryption password and the new password.
(Please note that after the password is changed, any previously exported keys will not
work anymore. The new encryption key needs to be downloaded if necessary, see
below.)
 Download the encryption key file: Enter the encryption password to download the
encryption key file. With this option, the encryption key can be saved as a file. The file is
also encrypted and can be used to unlock a volume, without knowing the real password
(see "Locking and unlocking disk volumes manually" below.) Please save the encryption
key file in a secure place!
 Save the encryption key: Save the encryption key on the NAS to automatically unlock
and mount the encrypted disk volume after the NAS restarts. Note that saving the
encryption key alone is not completely safe, as if the NAS is stolen, the volume
will be automatically unlocked after it restarts.
Locking and unlocking disk volumes manually
To lock a volume, log into the NAS as an administrator. Go to "Storage Manager" >
"STORAGE" > "Storage Space". Double click a volume to be locked to bring up the Volume
Management page and click "Actions" > "Encryption" > "Lock this Volume". Click "Yes".
To unlock a volume, log into the NAS as an administrator. Go to "Storage Manager" >
"STORAGE" > "Storage Space". Select a volume to be unlocked and click "Manage" > "
Unlock this volume". Choose either to enter the encryption password, or use the encryption
key file exported previously. Click "Apply". If the encryption password or the key file is
correct, the volume will be unlocked and become available.
