MaxScale PARSEC Authenticator

PARSEC Authenticator

The PARSEC (Password Authentication using Response Signed with Elliptic Curve) authentication plugin uses salted passwords, key derivation, extensible password storage format, and both server-side and client-side scrambles.

Similarly to the ed25519 authentication plugin, it signs the response with a ed25519 digital signature, but unlike the ed25519 authentication plugin, it uses the stock unmodified ed25519 as provided by OpenSSL.

This authentication plugin is intended to be used with MariaDB version 12 or later and requires that the service user has the SET USER grant.

MariaDB versions 11.6 or later that include the PARSEC authentication plugin are supported but the passwords for the users must be provided via the user mapping file. The documentation for the Ed25519 authenticator contains an example of how to configure the user mapping.

Configuration

To enable PARSEC authentication on a listener, the authenticator list must include parsecauth.

[Listener]
type=listener
address=127.0.0.1
port=3306
service=Service
authenticator=mariadbauth,parsecauth

To only allow PARSEC authentication, use authenticator=parsecauth.
