Generation of private key using des3 gets stuck
<p>I'm following <a href="https://devcenter.heroku.com/articles/ssl-endpoint#acquire-ssl-certificate" rel="noreferrer">Heroku's documentation</a> to generate a private key for an SSL certificate.</p>

<p>When I execute the command <code>openssl genrsa -des3 -out server.pass.key 2048</code>, I get the following result:</p>

<pre class="lang-none prettyprint-override"><code>$ openssl genrsa -des3 -out server.pass.key 2048
Loading 'screen' into random state - done
Generating RSA private key, 2048 bit long modulus
..........................+++
..................................................+++
</code></pre>

<p>I can't get to the prompt where I'm supposed to enter the passphrase for the keys.</p>

<p>I don't understand why OpenSSL fails to complete. I've generated keys without triple DES, so I guess the error is in the encryption. How can I get this solved?</p>
