一、生成PEM文件

这里以邮件发送接口为例https://api.mailgun.net/v3/，首先运行以下命令：

openssl s_client -host api.mailgun.net -port 443 -prexit -showcerts

执行结果如下：

CONNECTED(00000003)
depth=1 C = US, O = "thawte, Inc.", CN = thawte SHA256 SSL CA
verify error:num=20:unable to get local issuer certificate

 将输出内容保存为pem文件，这里我保存为名为mailgun.pem的文件。

 

二、将证书导入truststore文件

cp $JAVA_HOME/jre/lib/security/cacerts  trustore

本质上keyStore和strustStore文件格式上是一回事，keyStore存的一般是私钥，trustStore存放的是公钥。

 

导入证书（初始密码是changeit）：

keytool -import -alias gca -file mailgun.pem -keystore truststore

 导入成功会有提示。GOOD LUCK

 

三、参考

https://www.cloudera.com/documentation/enterprise/5-8-x/topics/cm_sg_create_key_trust.html

等
