 > *Tiller, found in Helm v2, has known security challenges. It requires administrative privileges and acts as a shared resource accessible to any authenticated user. Tiller can lead to privilege escalation as restricted users can impact other users. It is recommend to use Helm v3+ which does not contain Tiller for these reasons

For encrypting secret in etcd, we are using encryption in rest, this will cause, that there will not be secret key value in plain text format anymore in etcd.
