最近在做一个https双向认证的工作，领导先让我实现，我之前写了一篇文章，把tomcat的生成证书和配置的实现写了出来。
现在领导给了我服务器的CA证书的客户端证书和私钥，服务端信任证书，分别是crt和pem格式的文件，
试了很多方法，才把这个搞通，由于不同的平台，证书格式和版本差异很大，包括文本证书和二进制证书文件。
通过openSSL 很容易把证书转换出来，现有Linux主机，安装了openssl,
证书文件：client.crt ,server.crt ,client.pem
openssl pkcs12 -export -in client.crt -out client.pfx -inkey client.pem -passin pass:123456
生成的pfx格式的证书，可以安装在windows系统中，可以通过浏览器访问，
程序中由于双向认证，需要信任服务端证书，
把server.crt转换为keystore格式
keytool -importkeystore -v -srckeystore client.pfx -srcstoretype pkcs12 -srcstorepass 123456 -destkeystore client.keystore -deststoretype jks -deststorepass 123456
keytool -import -alias ca -trustcacerts -file server.crt -keystore client.keystore
把keystore设成客户端信任证书即可实现双向认证。

中间的重写方法是由于证书中的主机名IP与实际访问的不符合，这里是去除commonName的校验。
