"desc": "<p>The term "<a href=\"https://en.wikipedia.org/wiki/Perfect_forward_secrecy\">Forward Secrecy</a>" or "Perfect Forward Secrecy" describes a feature of\nkey-agreement (i.e., key-exchange) methods. That is, the server and client keys\nare used to negotiate new temporary keys that are used specifically and only for\nthe current communication session. Practically, this means that even if the\nserver's private key is compromised, communication can only be decrypted by\neavesdroppers if the attacker manages to obtain the key-pair specifically\ngenerated for the session.</p>\n<p>Perfect Forward Secrecy is achieved by randomly generating a key pair for\nkey-agreement on every TLS/SSL handshake (in contrast to using the same key for\nall sessions). Methods implementing this technique are called "ephemeral".</p>\n<p>Currently two methods are commonly used to achieve Perfect Forward Secrecy (note\nthe character "E" appended to the traditional abbreviations):</p>\n<ul>\n<li><a href=\"https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange\">DHE</a> - An ephemeral version of the Diffie Hellman key-agreement protocol.</li>\n<li><a href=\"https://en.wikipedia.org/wiki/Elliptic_curve_Diffie%E2%80%93Hellman\">ECDHE</a> - An ephemeral version of the Elliptic Curve Diffie Hellman\nkey-agreement protocol.</li>\n</ul>\n<p>Ephemeral methods may have some performance drawbacks, because key generation\nis expensive.</p>\n<p>To use Perfect Forward Secrecy using <code>DHE</code> with the <code>tls</code> module, it is required\nto generate Diffie-Hellman parameters and specify them with the <code>dhparam</code>\noption to <a href=\"#tls_tls_createsecurecontext_options\"><code>tls.createSecureContext()</code></a>. The following illustrates the use of\nthe OpenSSL command-line interface to generate such parameters:</p>\n<pre><code class=\"lang-sh\">openssl dhparam -outform PEM -out dhparam.pem 2048\n</code></pre>\n<p>If using Perfect Forward Secrecy using <code>ECDHE</code>, Diffie-Hellman parameters are\nnot required and a default ECDHE curve will be used.
