我正在尝试使用 Windows 和 OpenSSL 创建一个简单的 SSL 服务器。

    sd = socket(PF_INET, SOCK_STREAM, 0);
    //bzero(&addr, sizeof(addr));
    memset(&addr, 0, sizeof(addr));
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;
    if ( bind(sd, (struct sockaddr*)&addr, sizeof(addr)) != 0 )

        abort();
    }
    return sd;
}

SSL_CTX* InitServerCTX(void)

        X509_free(cert);
    }
    else
        printf("No certificates.\n");
}

void Servlet(SSL* ssl) /* Serve the connection -- threadable */
{   char buf[1024];
    char reply[1024];
    int sd, bytes;

    SSL_free(ssl);         /* release SSL state */
    //close(sd);          /* close connection */
    closesocket(sd);          /* close connection */
}

int main(int count, char *strings[])
{
    SSL_CTX *ctx;
    int server;
    char *portnum;

    if ( count != 2 )
    {
        printf("Usage: %s <portnum>\n", strings[0]);
        exit(0);
    }
    SSL_library_init();

    portnum = strings[1];
    ctx = InitServerCTX();        /* initialize SSL */
    LoadCertificates(ctx, "server.crt", "server.key"); /* load certs */
    server = OpenListener(atoi(portnum));    /* create server socket */
    while (1)
    {   struct sockaddr_in addr;
        socklen_t len = sizeof(addr);
        SSL *ssl;

        int client = accept(server, (struct sockaddr*)&addr, &len);  /* accept connection as usual */
        printf("Connection: %s:%d\n",inet_ntoa(addr.sin_addr), ntohs(addr.sin_port));
        ssl = SSL_new(ctx);              /* get new SSL state with context */
        SSL_set_fd(ssl, client);      /* set connection socket to SSL state */
        Servlet(ssl);         /* service connection */
    }
    //close(server);          /* close server socket */
    closesocket(server);          /* close server socket */
    SSL_CTX_free(ctx);         /* release context */
}

应用程序在此代码中停止。

if ( bind(sd, (struct sockaddr*)&addr, sizeof(addr)) != 0 )
{
    perror("can't bind port");
    abort();
}
  • Windows 7 x64
  • Visual C++ 2012
  • Win32 OpenSSL v1.0.1e

It looks like your post is mostly code; please add some more details.

我还不知道我要添加什么。

最佳答案

为了完整起见:

在 Windows 下，有必要像这样初始化网络堆栈 (WinSock):

WSADATA wsaData;
int iResult;

// Initialize Winsock
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != 0) {
    printf("WSAStartup failed: %d\n", iResult);
    return 1;
}

您也一定不要忘记在完成网络堆栈后调用 WSACleanup 以释放剩余资源。
