Constructor & Destructor Documentation

◆ MQTTClientComponent()

esphome::mqtt::MQTTClientComponent::MQTTClientComponent ( )

Member Function Documentation

◆ add_ssl_fingerprint()

void esphome::mqtt::MQTTClientComponent::add_ssl_fingerprint ( const std::array< uint8_t, SHA1_SIZE > & fingerprint )

Add a SSL fingerprint to use for TCP SSL connections to the MQTT broker.

To use this feature you first have to globally enable the ASYNC_TCP_SSL_ENABLED define flag. This function can be called multiple times and any certificate that matches any of the provided fingerprints will match. Calling this method will also automatically disable all non-ssl connections.

Warning: This is not secure and not how SSL is usually done. You'll have to add a separate fingerprint for every certificate you use. Additionally, the hashing algorithm used here due to the constraints of the MCU, SHA1, is known to be insecure.

Parameters

fingerprint The SSL fingerprint as a 20 value long std::array.
