openssl组件:
openssl: 多用途命令行工具，各功能分别使用子命令实现
libcrypto: 公共加密库
libssl: ssl协议的实现
PKI：Public Key Infrastructure
签证机构：CA
注册机构：RA
证书吊销列表：CRL
证书存取库：
openssl建立私有CA：
1、生成密钥 2、自签署证书 节点： 1、生成密钥对儿 2、生成证书签署请求 3、把请求发送给CA CA： 1、验正请求者信息；RA 2、签署证书； 3、把签好的证书发送给请求者；

What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.‘, the field will be left blank.
