Click the Add key button next to the desired volume to launch the Add Encryption Key button.
Type in the valid encryption key for the volume.
Click Save.
Important. The encryption key you add to the Encryption Keystore must be the same as specified when enabling encryption for the volume. Otherwise, any decription operations will fail.
Configuring Encryption Keystore
When configuring the Encryption Keystore in vStor, the user specifies an existing remote location for the keystore and credentials for the user with writing access to the specified directory.
You can edit the section by clicking the Edit button to launch the Edit Encryption Keystore dialog window.
Populate the dialog according to the indications below.
User
