This document describes how to update the default PKI configuration provided by ESP-AT. The PKI configuration includes certificates and keys for TLS clients, TLS servers, MQTT clients, and WPA2 Enterprise clients.

Introduction to PKI Configuration

The source file for the current default PKI configuration is located in the customized_partitions/raw_data directory, as shown below:

Function	Current Configuration	Related AT Commands
TLS client	Set 0 client configuration client_ca_00.crt client_cert_00.crt client_key_00.key Set 1 client configuration client_ca_01.crt client_cert_01.crt client_key_01.key	AT+CIPSTART AT+CIPSSLCCONF
TLS server	server_ca.crt server_cert.crt server.key	AT+CIPSERVER
MQTT client	mqtt_ca.crt mqtt_client.crt mqtt_client.key	AT+MQTTUSERCFG
WebSocket client	Set 0 client configuration wss_ca_00.crt wss_client_00.crt wss_client_00.key Set 1 client configuration wss_ca_01.crt wss_client_01.crt wss_client_01.key	AT+WSCFG
