Encryption Keystore is a remote location where encryption keys for vStor volumes are stored. The recommended location for the Encryption Keystore is the DPX Master Server, although all Linux machines are supported.
You can manage the keys in the keystore by clicking the Manage keys button to launch the Manage Keys dialog window.
To add encryption key to a volume, do the following:
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.
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
The Linux user with writing access to the keystore’s directory.
Password
The Linux user’s password.
Host
The hostname or IP address of the machine where the keystore is located.
Port
The port on which the machine with keystore listens.
Path
An existing absolute directory to be used as the Encryption Keystore. The path must be in Linux format.
Click Test to verify the keystore accessibility (optional).
Click Save. The configuration is now saved. The connection will also be tested when saving.
