The wolfMQTT client library has an Amazon Web Services example that demonstrates securely connecting over TLS provided by the wolfSSL embedded SSL/TLS library.

We setup an AWS IoT endpoint and testing device certificate. The AWS server uses a TLS client certificate for authentication. The example is located in /examples/aws/.  It subscribes to $aws/things/"AWSIOT_DEVICE_ID"/shadow/update/delta and publishes to $aws/things/"AWSIOT_DEVICE_ID"/shadow/update.

Everyone deserves to have their IoT data secure, and wolfSSL provides the best libraries to accomplish that! wolfSSL supports up to TLS 1.3, FIPS 140-2, expansive support for hardware cryptography, and more!  Secure-IoT-Love from the wolfSSL team!
