阿里云提供的证书 本地如何配置

import paho.mqtt.client as paho

def MQTTpub(msg):

mqttc = paho.Client(client_id="xxxx@@@xxxx", clean_session=True, protocol=paho.MQTTv311)
mqttc.username_pw_set("xxxxxx", "xxxxxx")

ca_certs = "xxxxxxx"
certfile = "xxxxxxxx"
keyfile = "xxxxxxxx"
mqttc.tls_set(ca_certs, certfile, keyfile, cert_reqs=paho.ssl.CERT_REQUIRED, tls_version=paho.ssl.PROTOCOL_TLSv1, ciphers=None)

mqttc.connect("mqtt.cn-hangzhou.aliyuncs.com", 8883, 60)
mqttc.publish("test/chat", msg, 0)
mqttc.disconnect()

ca_certs 应该就是官网下载的证书了
certfile/keyfile 要如何生成
