LightSail support for encryption-at-rest

Hello,

Yes, to help keep your data secure, all Lightsail attached disks and disk snapshots are encrypted at rest by default, using keys that Lightsail manages on your behalf. Lightsail also provides encryption of data as it moves between Lightsail instances and attached disks.

Lightsail also automatically encrypts your data at rest and in motion for increased security and stores your database password for easy and secure connections to your database.
