MySQL 5.7 Reference Manual  /  ...  /  The MySQL Keyring

6.4.4 The MySQL Keyring

MySQL Server supports a keyring that enables internal server components and plugins to securely store sensitive information for later retrieval. The implementation comprises these elements:

Warning

For encryption key management, the keyring_file and keyring_encrypted_file plugins are not intended as a regulatory compliance solution. Security standards such as PCI, FIPS, and others require use of key management systems to secure, manage, and protect encryption keys in key vaults or hardware security modules (HSMs).

Within MySQL, uses of the keyring include:

For general keyring installation instructions, see Section 6.4.4.1, “Keyring Plugin Installation”. For installation and configuration information specific to a given keyring plugin, see the section describing that plugin.

For information about using the keyring UDFs, see Section 6.4.4.8, “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 service and writing keyring plugins, see Section 5.5.6.2, “The Keyring Service”, and Writing Keyring Plugins.
