Any update on this question because it is 2020 and the question is 7 years ago. In linode I know how to do this because they provided tutorial on this https://www.linode.com/docs/security/encryption/use-luks-for-full-disk-encryption/. What about digitalocean? I think I might use linode if this is not possible. Can anyone confirm ?
