Each client and each\nserver must have a private key. A private key is created like this:\n\n</p>\n<pre><code>openssl genrsa -out ryans-key.pem 2048</code></pre>\n<p>All servers and some clients need to have a certificate. Certificates are public\nkeys signed by a Certificate Authority or self-signed. The first step to\ngetting a certificate is to create a &quot;Certificate Signing Request&quot; (CSR)\nfile. This is done with:\n\n</p>\n<pre><code>openssl req -new -sha256 -key ryans-key.pem -out ryans-csr.pem</code></pre>\n<p>To create a self-signed certificate with the CSR, do this:\n\n</p>\n<pre><code>openssl x509 -req -in ryans-csr.pem -signkey ryans-key.pem -out ryans-cert.pem</code></pre>\n<p>Alternatively you can send the CSR to a Certificate Authority for signing.\n\n</p>\n<p>(TODO: docs on creating a CA, for now interested users should just look at\n<code>test/fixtures/keys/Makefile</code> in the Node source code)\n\n</p>\n<p>To create .pfx or .p12, do this:\n\n</p>\n<pre><code>openssl pkcs12 -export -in agent5-cert.pem -inkey agent5-key.pem \\\n    -certfile ca-cert.pem -out agent5.pfx</code></pre>\n<ul>\n<li><code>in</code>:  certificate</li>\n<li><code>inkey</code>: private key</li>\n<li><code>certfile</code>: all CA certs concatenated in one file like\n<code>cat ca1-cert.pem ca2-cert.pem &gt; ca-cert.pem</code></li>\n</ul>\n",

They are considered insecure and could be easily\ncompromised as was shown by [CVE-2014-3566][]. However, in some situations, it\nmay cause problems with legacy clients/servers (such as Internet Explorer 6).\nIf you wish to enable SSLv2 or SSLv3, run node with the <code>--enable-ssl2</code> or\n<code>--enable-ssl3</code> flag respectively.  In future versions of Node.js SSLv2 and\nSSLv3 will not be compiled in by default.\n\n</p>\n<p>There is a way to force node into using SSLv3 or SSLv2 only mode by explicitly\nspecifying <code>secureProtocol</code> to <code>&#39;SSLv3_method&#39;</code> or <code>&#39;SSLv2_method&#39;</code>.\n\n</p>\n<p>The default protocol method Node.js uses is <code>SSLv23_method</code> which would be more\naccurately named <code>AutoNegotiate_method</code>. This method will try and negotiate\nfrom the highest level down to whatever the client supports.  To provide a\nsecure default, Node.js (since v0.10.33) explicitly disables the use of SSLv3\nand SSLv2 by setting the <code>secureOptions</code> to be\n<code>SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2</code> (again, unless you have passed\n<code>--enable-ssl3</code>, or <code>--enable-ssl2</code>, or <code>SSLv3_method</code> as <code>secureProtocol</code>).\n\n</p>\n<p>If you have set <code>secureOptions</code> to anything, we will not override your\noptions.\n\n</p>\n<p>The ramifications of this behavior change:\n\n</p>\n<ul>\n<li>If your application is behaving as a secure server, clients who are <code>SSLv3</code>\nonly will now not be able to appropriately negotiate a connection and will be\nrefused. In this case your server will emit a <code>clientError</code> event. The error\nmessage will include <code>&#39;wrong version number&#39;</code>.</li>\n<li>If your application is behaving as a secure client and communicating with a\nserver that doesn&#39;t support methods more secure than SSLv3 then your connection\nwon&#39;t be able to negotiate and will fail. In this case your client will emit a\nan <code>error</code> event. The error message will include <code>&#39;wrong version number&#39;</code>.</li>\n</ul>\n",
