title: Can't open config file: /usr/local/ssl/openssl.cnf on Windows
body: <p>I have installed OpenSSL 64. I want to use a certificate for my nodejs https server. I ran the following command:</p>
  
  <pre><code>openssl genrsa -out subdomain.domain.com.key 1024
  </code></pre>
  
  <p>But I have got the error:</p>
  
  <pre><code>WARNING: can't open config file: /usr/local/ssl/openssl.cnf
  Loading 'screen' into random state - done
  Generating RSA private key, 1024 bit long modulus
  .........++++++
  .........................................++++++
  unable to write 'random state'
  e is 65537 (0x10001)
  </code></pre>
  
  <p>How can I resolve it?<br/>
  Is this the right command?<br/></p>
