MySQL 密钥环最初使用服务器插件实现密钥存储功能，但从 MySQL 8.0 开始，开始过渡到使用组件基础架构。此过渡包括修订密钥环插件的底层实现以使用组件基础架构。这是通过名为 daemon_keyring_proxy_plugin 的插件来实现的，该插件充当插件和组件服务 API 之间的桥梁，并使密钥环插件能够继续使用，而无需更改用户可见的特性。MySQL Keyring originally implemented keystore capabilities using server plugins, but began transitioning to use the component infrastructure in MySQL 8.0. The transition includes revising the underlying implementation of keyring plugins to use the component infrastructure. This is facilitated using the plugin named daemon_keyring_proxy_plugin that acts as a bridge between the plugin and component service APIs, and enables keyring plugins to continue to be used with no change to user-visible characteristics.

daemon_keyring_proxy_plugin 是内置的，无需进行安装或启用操作。daemon_keyring_proxy_plugin is built in and nothing need be done to install or enable it.
