Disk Encryption Tab

The Disk Encryption tab enables you to encrypt disks that are attached to the virtual machine.

To enable disk encryption, select the Enable Disk Encryption check box.

Settings are available to configure the cipher used for encryption and the encryption password.

All files related to the virtual machine except disk images are stored unencrypted. To encrypt these files, use the VBoxManage encryptvm command as described in Encryption of VMs.
