The error log can contain query text and data in some cases, including crashes, assertion failures, and cases where InnoDB write monitor output to the log to aid in debugging. The MariaDB error log is not encrypted.This affects only non-temporary Aria tables though. The Aria log is not encrypted ( MDEV-8587).File-based general query log and slow query log cannot be encrypted ( MDEV-9639).Send it to syslog and configure the protection there instead. The Audit plugin cannot create encrypted output.However, this file is encrypted in MariaDB Enterprise Server 10.4. The disk-based Galera gcache is not encrypted in the community version of MariaDB Server ( MDEV-9639).However, MariaDB's fork, MariaDB Backup, can back up encrypted instances. Percona XtraBackup cannot back up instances that use encrypted InnoDB.mysqlbinlog can read encrypted binary logs only when -read-from-remote-server is used ( MDEV-8813). #KEEP OLD FILE AFTER ENCRYPTO HOW TO#Only the MariaDB server knows how to decrypt the data, in particular.frm files) and data sent to the client are not encrypted (but see Secure Connections). Only data and only at rest is encrypted.These limitations exist in the data-at-rest encryption implementation: everything, excluding individual tablesĪdditionally, one can choose to encrypt InnoDB log files (recommended).everything - all tablespaces (with all tables).MariaDB allows the user to configure flexibly what to encrypt. Encryption is also supported for the Aria storage engine, but only for tables created with ROW_FORMAT=PAGE (the default), and for the binary log (replication log). MariaDB encryption is fully supported for the InnoDB storage engines. Which Storage Engines Does MariaDB Encryption Support? Using encryption has an overhead of roughly 3-5%. This assumes that encryption keys are stored on another system. This functionality is also known as "Transparent Data Encryption (TDE)". MariaDB got Data-at-Rest Encryption with MariaDB 10.1. Steal a hard disk and get access to the original data. Having tables encrypted makes it almost impossible for someone to access or Which Storage Engines Does MariaDB Encryption Support?.
