python socketserver模块开启ssl双向认证

server端代码如下

复制代码

import socketserver
import ssl

# 需要校验客户端
ssl_context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
# 发给客户端
ssl_context.load_cert_chain(certfile="./server.crt", keyfile="./server.key")
# 信任库
ssl_context.load_verify_locations(./ca.crt")
ssl_context.verify_mode=ssl.CERT_REQUIRED
# 检查主机名是否与提供的证书中的主机名匹配
ssl_context.check_hostname=False



class MyHandler(socketserver.BaseRequestHandler):
    def handle(self):
        # 接收客户端的数据
        data = self.request.recv(1024).strip()
        print(f'Received from client: {data.decode()}')
        # 发送响应给客户端
        response = b'Hello, Client!'
        self.request.sendall(response)


if __name__ == '__main__':
    server = socketserver.TCPServer(('0.0.0.0', 1234), MyHandler)
    server.socket = ssl_context.wrap_socket(server.socket, server_side=True)
    server.serve_forever()

client端代码如下

复制代码

import socket
import ssl

# 定义服务器的地址和端口
server_address = ('localhost', 1234)
ssl_context = ssl.SSLContext(ssl.PROTOCOL_TLS)
ssl_context.check_hostname = False
# 加载证书链，用于发给对端，相当于keystore
ssl_context.load_cert_chain(certfile="./server.crt", keyfile="./server.key")
ssl_context.verify_mode=ssl.CERT_REQUIRED
# trustStore
ssl_context.load_verify_locations(cafile="D:\code\Quantity\ca.crt")
# 创建一个TCP套接字
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
csocket = ssl_context.wrap_socket(client_socket, server_side=False)
try:
    # 连接到服务器
    csocket.connect(server_address)

    # 发送数据给服务器
    data = b'Hello, Server!'
    csocket.sendall(data)

    # 接收服务器的响应数据
    response = csocket.recv(1024)
    print('Received from server:', response.decode())
finally:
    # 关闭客户端套接字
    csocket.close()
