golang实现openssl自签名双向认证的详细步骤
作者:赴前尘
这篇文章主要介绍了golang实现openssl自签名双向认证的详细步骤,本文分步骤给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友参考下吧
第一步:生成CA、服务端、客户端证书
1. 生成CA根证书 生成CA证书私钥
openssl genrsa -out ca.key 4096
创建ca.conf 文件
[ req ] default_bits = 4096 distinguished_name = req_distinguished_name [ req_distinguished_name ] countryName = Country Name (2 letter code) countryName_default = CN stateOrProvinceName = State or Province Name (full name) stateOrProvinceName_default = JiangSu localityName = Locality Name (eg, city) localityName_default = NanJing organizationName = Organization Name (eg, company) organizationName_default = Sheld commonName = Common Name (e.g. server FQDN or YOUR name) commonName_max = 64 commonName_default = localhost
生成根证书签发申请文件(csr文件)
openssl req \ -new \ -sha256 \ -out ca.csr \ -key ca.key \ -config ca.conf
生成自签发根证书(crt文件)
openssl x509 \ -req \ -days 3650 \ -in ca.csr \ -signkey ca.key \ -out ca.pem
2. 生成服务端证书
生成服务端私钥
openssl genrsa -out server.key 2048
创建 server.conf 文件
[ req ] default_bits = 2048 distinguished_name = req_distinguished_name req_extensions = req_ext [ req_distinguished_name ] countryName = Country Name (2 letter code) countryName_default = CN stateOrProvinceName = State or Province Name (full name) stateOrProvinceName_default = JiangSu localityName = Locality Name (eg, city) localityName_default = NanJing organizationName = Organization Name (eg, company) organizationName_default = Sheld commonName = Common Name (e.g. server FQDN or YOUR name) commonName_max = 64 commonName_default = localhost # 此处尤为重要,需要用该服务名字填写到客户端的代码中 [ req_ext ] subjectAltName = @alt_names [alt_names] DNS.1 = localhost IP.1 = 127.0.0.1
生成服务端签发申请文件(csr文件)
openssl req \ -new \ -sha256 \ -out server.csr \ -key server.key \ -config server.conf
使用CA证书签署服务器证书
openssl genrsa -out client.key 2048
3. 生成客户端证书
生成客户端私钥
openssl genrsa -out client.key 2048
创建 client.conf 文件
[ req ] default_bits = 2048 distinguished_name = req_distinguished_name [ req_distinguished_name ] countryName = Country Name (2 letter code) countryName_default = CN stateOrProvinceName = State or Province Name (full name) stateOrProvinceName_default = JiangSu localityName = Locality Name (eg, city) localityName_default = NanJing organizationName = Organization Name (eg, company) organizationName_default = Sheld commonName = Common Name (e.g. server FQDN or YOUR name) commonName_max = 64 commonName_default = localhost
生成客户端端签发申请文件(csr文件)
openssl req \ -new \ -sha256 \ -out client.csr \ -key client.key \ -config client.conf
使用CA证书签署客户端器证书
openssl x509 \ -req \ -days 3650 \ -CA ca.pem \ -CAkey ca.key \ -CAcreateserial \ -in client.csr \ -out client.pem
第二步:golang 服务端、客户端代码编写
1. 项目目录结构
2. 服务端代码:server.go
package main import ( "crypto/tls" "crypto/x509" "fmt" "net/http" "os" ) type MyHandler struct { } func (h *MyHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "Hello, HTTPS!") } func main() { pool := x509.NewCertPool() // 创建证书池 caCertPath := "./cert/ca.pem" caCrt, err := os.ReadFile(caCertPath) // 读取本地CA证书文件 if err != nil { fmt.Println("ReadFile err:", err) return } pool.AppendCertsFromPEM(caCrt) // 将证书添加到证书池中 s := &http.Server{ // 创建 HTTP服务器实例,并设置服务器的监听地址(本例中是127.0.0.1:8088)、处理器(即上面定义的myhandler结构体)、以及TLS配置。 Addr: "127.0.0.1:8088", Handler: &MyHandler{}, TLSConfig: &tls.Config{ ClientCAs: pool, // 指定客户端需要验证的CA证书池(即上面创建的pool) ClientAuth: tls.RequireAndVerifyClientCert, // 要求客户端在发送请求时必须携带证书 }, } err = s.ListenAndServeTLS("./cert/server.pem", "./cert/server.key") if err != nil { fmt.Println("ListenAndServeTLS err:", err) } }
3. 客户端代码:client.go
package main import ( "crypto/tls" "crypto/x509" "fmt" "io" "net/http" "os" ) func main() { pool := x509.NewCertPool() // 创建 x509.CertPool,用于存储CA证书 caCertPath := "./cert/ca.pem" // 从文件中读取CA证书的内容 caCrt, err := os.ReadFile(caCertPath) if err != nil { fmt.Println("ReadFile err:", err) return } pool.AppendCertsFromPEM(caCrt) // 将CA证书添加到CertPool中 cliCrt, err := tls.LoadX509KeyPair("./cert/client.pem", "./cert/client.key") //加载客户端证书和私钥 if err != nil { fmt.Println("Loadx509keypair err:", err) return } tr := &http.Transport{ // 创建一个http.Transport,并配置TLS相关信息 TLSClientConfig: &tls.Config{ RootCAs: pool, // 设置根证书池 Certificates: []tls.Certificate{cliCrt}, // 设置客户端证书和私钥 }, } client := &http.Client{Transport: tr} // 创建一个http.Client,并设置Transport为上面创建的Transport对象 resp, err := client.Get("https://127.0.0.1:8088") // 使用创建的Client发送GET请求 if err != nil { fmt.Println("Http Get error:", err) return } defer resp.Body.Close() body, err := io.ReadAll(resp.Body) // 读取并打印响应体的内容 fmt.Println(string(body)) }
第三步:验证
1. 运行服务端
go run ./server/server.go
2. 运行客户端
运行客户端
go run ./client/client.go
