Secrets Management Cheat Sheet — 4.2.2 Bring Your Own Key versus Cloud Provider Key

The less trust you have in the cloud provider, the more you will want to manage yourself.

You can either directly import or generate this key at the key management solution or using cloud HSM supported by the cloud provider.
