MariaDB Encryption - unknown variable 'plugin-load-add=file_key_management.dll' I'm really new to MariaDB and I need to set up encryption at rest. I'm running MariaDB 10.3 on Windows Svr 2012R2.

I have created a key and added the following to my config file (my.ini)

plugin-load-add=file_key_management.dll
file-key-management
file-key-management-filename = "C:/MariaDB/data/keys.txt"
innodb-encrypt-tables
innodb-encrypt-log
innodb-encryption-threads=4


The service starts fine. However when I go to open the MySQL Client I get the following error:


  C:\Program Files\MariaDB 10.3\bin\mysql.exe: unknown variable 'plugin-load-add=file_key_management.dll'


The dll is present and in the plugin-dir location specified in the config file.

Can anyone help me please?
mariadb from version 10.3 use other command in config: 
[mariadb]
plugin_load_add = file_key_management
