Encrypting Aria Data
MariaDB Enterprise Server and MariaDB Community Server supports data-at-rest encryption, which secures data on the file system. The server and storage engines encrypt data before writes and decrypts during reads, ensuring that the data is only unencrypted when accessed directly through the server.
Aria supports the following data-at-rest encryption features:
All tables can be automatically encrypted.
Internally-created temporary on-disk tables can be automatically encrypted.
Additional information is available on the MariaDB Knowledge Base.
