  1. POProblems Using OpenSSL in Windows 7
    text
    copied!<p>I noticed some problems between installing OpenSSL on Windows XP Professional and Windows 7 Professional. For both OSs, I downloaded the <code>Win32 OpenSSL v1.0.0d</code> and <code>Visual C++ 2008</code> 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:</p> <ul> <li><p>From the MS-DOS command prompt, I tried to create a root CA with</p> <pre><code>openssl x509 -req -in rootreq.pem -sha1 -extensions v3_ca -signkey rootkey.pem -out rootcert.pem </code></pre></li> </ul> <p>but was given the following error <code>unable to write random state</code>. Windows XP worked fine.</p> <ul> <li>I compiled a simple SSL web server using the OpenSSL API, but when I try to connect using</li> </ul> <blockquote> <pre><code>openssl s_client -connect 127.0.0.1:16001 </code></pre> </blockquote> <p>I get the following response</p> <pre><code>Loading 'screen' into random state - done connect: No such file or directory connect:errno=0 </code></pre> <p>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.</p> <p>Does anyone know what the problem may be ? Are there extra steps that I need to take when installing on Windows 7? </p> <p>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.</p> <pre><code>/////////////////// Code /////////////////////////////////// // Simple OpenSSL Webserver // Compiler : MSVS 2010 Professional // Language: C / C++ int main(int argc, char *argv[]) { BIO *acc, *client; SSL *ssl; SSL_CTX *ctx; THREAD_TYPE tid; init_OpenSSL( ); seed_prng( ); 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) &lt;= 0) int_error("Error binding server socket"); printf ("BIO_do_accept\n"); for (;;) { if (BIO_do_accept(acc) &lt;= 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; } </code></pre>
