MariaDB Encryption at rest - provide key from app

In the past, I use Sybase anywhere db as my db server. I can encrypt the whole db with password, and from my application, i provide password inside connection string to gain access to server.


I want to use the same / similar scenario with mariaDB.


Suppose i have mariadb with encryption at rest.


1- can i provide key from my application directly?


or build wcf service that mariadb call to get the key it needs when starting


2- can i prevent resetting admin password on encrypted db?


3- Is there any other dbs that support this scenario ?


thanks
