Elliptic curve cryptography is ok. AES is solid. Use "forward secret" ciphers where possible (Diffie-Hellman Ephemeral, aka DHE, and Elliptic Curve Diffie-Hellman Ephemeral, aka ECDHE) so that people recording your encrypted communications can't re-play them later when they get your server's private key. :)</div><div><br></div><div>Alan<br><div><br></div><div>[0] <a href="https://www.lightbluetouchpaper.org/2015/05/02/meeting-snowden-in-princeton/" target="_blank">https://www.lightbluetouchpaper.org/2015/05/02/meeting-snowden-in-princeton/</a></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 5, 2015 at 12:21 AM, Andreas Tauscher via Linux <span dir="ltr"><<a href="mailto:linux@lists.habari.co.tz" target="_blank">linux@lists.habari.co.tz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class=""><br>

</span>It was only an announcement what will be done in the medium/long term.<br>
What finally will be disabled: The discussion is still going on. The<br>
only what is sure: http2 is working only over TLS.<br>
Also the W3C is discussing which features should or must be available<br>
only over TLS.<br>
Will take some time.<br>
