一、ssl/tls协议

二、mosquitto添加broker证书

MQTT协议端口号

listener 1883
protocol mqtt

订阅主题持久化

persistence true
persistence_location D:softwaremosquittodata

开启日志记录

log_dest file D:softwaremosquittomosquitto.log
log_type all

开启密码验证

password_file D:softwaremosquittopwfile.example
allow_anonymous false
#不需要对端提供证书
require_certificate false
#证书
cafile D:softwaremosquittocertsca.crt
certfile D:softwaremosquittocertsserver.crt
keyfile D:softwaremosquittocertsserver.key

三、wireshark抓包
