Jan SchaumannOpenSSH 10.0 just landed, now completely removing DSA signature support (you've been warned, repeatedly :-) and finite-field diffie-hellman key exchange.

Anton ArapovOpenSSL is advancing into the quantum era with the upcoming release of OpenSSL 3.5, integrating post-quantum cryptographic algorithms such as ML-KEM (FIPS 203), ML-DSA (FIPS 204), and SLH-DSA (FIPS 205). This development ensures enhanced security against emerging quantum computing threats. For an in-depth analysis, refer to the article by Prof Bill Buchanan OBE FRSE: <a href="https://medium.com/asecuritysite-when-bob-met-alice/no-excuses-openssl-enters-the-quantum-age-ad29af287273" rel="nofollow noopener" translate="no" target="_blank">https://medium.com/asecuritysite-when-bob-met-alice/no-excuses-openssl-enters-the-quantum-age-ad29af287273</a><a href="https://infosec.exchange/tags/openssl" class="mention hashtag" rel="nofollow noopener" target="_blank">#openssl</a> <a href="https://infosec.exchange/tags/pqc" class="mention hashtag" rel="nofollow noopener" target="_blank">#pqc</a>

Alexander Hansen FærøyThis is undoubtedly the most promising Post-Quantum TLS deployment situation I have seen for <a href="https://mastodon.social/tags/Tor" class="mention hashtag" rel="nofollow noopener" target="_blank">#Tor</a> since we started discussing it more actively in the team. Very exciting!I hope that OpenSSL 3.5, when released, will make it into <a href="https://mastodon.social/tags/Debian" class="mention hashtag" rel="nofollow noopener" target="_blank">#Debian</a> Trixie. That would make deployment of this so much more snappy and easy for the Tor network to upgrade, but that may be dreaming. The timelines here look quite difficult for that to happen, but let's hope.<a href="https://mastodon.social/tags/cryptography" class="mention hashtag" rel="nofollow noopener" target="_blank">#cryptography</a> <a href="https://mastodon.social/tags/pqc" class="mention hashtag" rel="nofollow noopener" target="_blank">#pqc</a> <a href="https://mastodon.social/tags/pqcrypto" class="mention hashtag" rel="nofollow noopener" target="_blank">#pqcrypto</a>
