C.<a href="https://mastodon.cr.yp.to/@djb" class="u-url mention" rel="nofollow noopener" target="_blank">@djb</a> (Daniel J. Bernstein) tooted about a new blog post[1] he published. It's here: <a href="https://blog.cr.yp.to/20250118-flight.html" rel="nofollow noopener" translate="no" target="_blank">https://blog.cr.yp.to/20250118-flight.html</a>It's interesting. He's a <a href="https://mindly.social/tags/mathematician" class="mention hashtag" rel="nofollow noopener" target="_blank">#mathematician</a> and software guy that in more recent years has been known mostly for his work in <a href="https://mindly.social/tags/cryptography" class="mention hashtag" rel="nofollow noopener" target="_blank">#cryptography</a>, <a href="https://mindly.social/tags/theoretical" class="mention hashtag" rel="nofollow noopener" target="_blank">#theoretical</a> and <a href="https://mindly.social/tags/practical" class="mention hashtag" rel="nofollow noopener" target="_blank">#practical</a>. You're probably using his <a href="https://mindly.social/tags/Curve25519" class="mention hashtag" rel="nofollow noopener" target="_blank">#Curve25519</a> every day in your <a href="https://mindly.social/tags/communications" class="mention hashtag" rel="nofollow noopener" target="_blank">#communications</a>.I'm not a mathematician (by a long shot), but it's written in a pretty accessible manner - it's not <a href="https://mindly.social/tags/formulae" class="mention hashtag" rel="nofollow noopener" target="_blank">#formulae</a> and <a href="https://mindly.social/tags/turgid" class="mention hashtag" rel="nofollow noopener" target="_blank">#turgid</a> academic <a href="https://mindly.social/tags/prose" class="mention hashtag" rel="nofollow noopener" target="_blank">#prose</a>.The central point he's getting at, by my possibly-mistaken understanding of it, is that current "common sense" about when attacks against pre-quantum cryptography like <a href="https://mindly.social/tags/RSA" class="mention hashtag" rel="nofollow noopener" target="_blank">#RSA</a> (and therefore when post-quantum cryptography becomes critical) are badly mistaken - based on bad assumptions about how attacks work, how they're implemented, and on badly <a href="https://mindly.social/tags/extrapolating" class="mention hashtag" rel="nofollow noopener" target="_blank">#extrapolating</a> from those bad assumptions using logic that doesn't actually represent the way attacks are developed and become practical.TL;DR is something along the lines of "<a href="https://mindly.social/tags/quantum" class="mention hashtag" rel="nofollow noopener" target="_blank">#quantum</a> cryptographic attacks against RSA will be practical sooner than most people think, and you should be deploying quantum-resistant cryptography now, not later".It's worth reading if you're at all interested in <a href="https://mindly.social/tags/crypto" class="mention hashtag" rel="nofollow noopener" target="_blank">#crypto</a> and <a href="https://mindly.social/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#security</a> stuff.He also mentions a project he's involved in that has been discussed separately, transparent post-quantum tunnelling for unmodified <a href="https://mindly.social/tags/server" class="mention hashtag" rel="nofollow noopener" target="_blank">#server</a> and <a href="https://mindly.social/tags/client" class="mention hashtag" rel="nofollow noopener" target="_blank">#client</a> <a href="https://mindly.social/tags/software" class="mention hashtag" rel="nofollow noopener" target="_blank">#software</a>. Link in post.[1] Written more like a conference presentation, FWIW.

A chill sat on the wind, not cold, but noticeably cooler than the rest of the surrounding air. Then the two rods crossed, and the door slammed in front of her.
