Problems Using OpenSSL in Windows 7

I noticed some problems between installing OpenSSL on Windows XP Professional and Windows 7 Professional. For both OSs, I downloaded the Win32 OpenSSL v1.0.0d and Visual C++ 2008 Redistributables binaries from the Shining Light Productions website. Both installed with no problems on both machines. However, on the Windows 7 machine, I encountered the following problems using the OpenSSL exe and API:

• From the MS-DOS command prompt, I tried to create a root CA with

  openssl x509 -req -in rootreq.pem -sha1  -e开发者_开发技巧xtensions v3_ca 
    -signkey rootkey.pem -out rootcert.pem
  

but was given the following error unable to write random state. Windows XP worked fine.

• I compiled a simple SSL web server using the OpenSSL API, but when I try to connect using

openssl s_client -connect 127.0.0.1:16001

I get the following response

Loading 'screen' into random state - done
connect: No such file or directory
connect:errno=0

Once again, Windows XP returned a better response. If you look at my attached code, it appears that the second BIO_do_accept never gets called.

Does anyone know what the problem may be ? Are there extra steps that I need to take when installing on Windows 7?

FYI - I also tried installing the 64 bit binaries on Windows 7 as well, but I got the same results. I really need to get this up and running on my Windows 7 machine, so any help is appreciated.

    ctx = setup_server_ctx(  );

    acc = BIO_new_accept(PORT);

    printf ("BIO_new_accept\n");

    if (!acc)
        int_error("Error creating server socket");

    if (BIO_do_accept(acc) <= 0)
        int_error("Error binding server socket");

    printf ("BIO_do_accept\n");

    for (;;)
    {
        if (BIO_do_accept(acc) <= 0)
            int_error("Error accepting connection");

        printf ("BIO_do_accept2\n");

        client = BIO_pop(acc);

        printf ("BIO_pop\n");

        if (!(ssl = SSL_new(ctx)))
            int_error("Error creating SSL context");

        printf ("SSL_new\n");

        SSL_set_bio(ssl, client, client);

        printf ("SSL_set_bio\n");

        THREAD_CREATE(tid, (void *)server_thread, ssl);
    }

    SSL_CTX_free(ctx);
    BIO_free(acc);
    return 0;
}

I have success using the MinGW-w64 platform to build my OpenSSL applications (both for x86 and x64 Windows), and I also had some issues with the Shining Light binaries.

It is quite easy to set up, there are some instructions and a sample application at http://www.blogcompiler.com/2011/12/21/openssl-for-windows/

Thanks for the answer. I discovered that the best way was to compile everything myself. I found a good tutorial at the following site - http://www.askyb.com/windows/compiling-and-installing-openssl-for-32-bit-windows/

when you click on command prompt right click and click run as administrator that should clear up your issue
