利用openssl自制ca证书以及ssl证书
搞一个steam社区的本地反带，搞了一天
前提安装openssl" title="openssl">openssl
server私钥openssl genrsa -out server.key 1024
server公钥
openssl rsa -in server.key -pubout -out server.pem
client私钥
openssl genrsa -out client.key 1024
client公钥
openssl rsa -in client.key -pubout -out client.pem
注册ca，让自己变成注册商，自签证书后导入到可信任证书
ca私钥
openssl genrsa -out ca.key 1024
自签证书
openssl req -config openssl.cnf -key ca.key -new -x509 -days 3650 -sha256 -extensions v3_ca -out ca.crt
制作服务器私钥，和请求文件
私钥
openssl genrsa -out server.key 1024
私钥请求文件
openssl req -config openssl.cnf -new -key server.key -out server.csr
echo 00 > serial | copy nul index.txt
用请求文件到ca签发，生成ca_server.crt
ca签发
openssl ca -config openssl.cnf -extensions server_cert -days 3650 -md sha256 -in server.csr -out ca_server.crt
系统已经有了你的ca机构证书，所以服务器证书就会被认为是正规ca机构签发的
最后用server.keyg和ca_server.crt
openssl.cnf
