MySQL 8.0 Reference Manual  /  ...  /  The MySQL Keyring

Pre-General Availability Draft: 2018-03-17

6.5.4 The MySQL Keyring

MySQL Server supports a keyring service that enables internal server components and plugins to securely store sensitive information for later retrieval. The implementation is plugin-based:

The InnoDB storage engine uses the keyring to store its key for tablespace encryption. InnoDB can use any supported keyring plugin.

For general keyring installation instructions, see Section, “Keyring Plugin Installation”. For information specific to a given keyring plugin, see the section describing that plugin.

For information about using the keyring UDFs, see Section, “General-Purpose Keyring Key-Management Functions”.

Keyring plugins and UDFs access a keyring service that provides the interface for server components to the keyring. For information about accessing the keyring plugin service and writing keyring plugins, see Section 29.3.2, “The Keyring Service”, and Section, “Writing Keyring Plugins”.
