ESPressio Security

Transport-neutral authenticated encryption, authentication, replay protection, and security policy for the Flowduino ESPressio Development Platform.

Current Version — 0.3.0

Security 0.3.0 owns the optional Event representation of its own transport-security lifecycle. The Security core remains independent of ESPressio Event; Event is acquired only when the application explicitly selects the Security Event integration.

Core dependency

Security 0.3.0
    -> Observable >= 3.0.1 < 4.0.0

Security remains independent of ESP-Now, Sockets, Command, Serial, and Event at the core layer.

Optional Event integration

Security 0.3.0 provides:

#include <ESPressio_SecurityEvents.hpp>
#include <ESPressio_TransportSecurityEventBridge.hpp>

The integration requires:

ESPressio Event >= 6.0.0 < 7.0.0

and converts ITransportSecurityObserver notifications into asynchronous Event types for configuration, session, replay-protection, and failure lifecycle changes.

The public header and class names remain unchanged from their previous location in ESPressio Event; ownership now matches the Security domain.

Dependency direction

Security core
    -> Observable

Security Event integration
    - - -> Event

Event 6.0.0 does not depend back on Security. The standard ESPressio_Security.hpp umbrella does not include the Event integration.
