Crate rmqtt_auth_http 

HTTP-based authentication and ACL plugin for RMQTT.

Delegates client authentication and publish/subscribe ACL checks to an external HTTP API. Supports flexible auth logic based on custom HTTP endpoint responses.

Architecture

• Hooks into ClientAuthenticate, ClientSubscribeCheckAcl, and MessagePublishCheckAcl events.
• Sends HTTP POST requests to configurable URLs with client credentials and connection metadata as JSON payload.
• Caches authentication results with configurable TTL to reduce HTTP call overhead.
• Supports username/password, client ID, and certificate-based authentication flows.
