OpenSSL 4.0 for NGINX: Why We Ship 3.5 LTS Instead
by Danila Vershinin, August 30, 2026
OpenSSL 4.0 for NGINX drops out of support in May 2027. OpenSSL 3.5 LTS runs to April 2030 and already does post-quantum key exchange. Here is the arithmetic behind our choice, and the one 4.0 feature worth having.

by Danila Vershinin, August 29, 2026
Every Debian and Ubuntu suite we publish now links our ABI-isolated OpenSSL 3.5 LTS build, so post-quantum key exchange, Encrypted Client Hello and TLS certificate compression arrive on DEB too. Ubuntu 20.04’s NGINX no longer links end-of-life OpenSSL 1.1.1.

by Danila Vershinin,
NGINX certificate compression (RFC 8879) shrinks the TLS handshake by around 20% on every fresh connection, and it takes one directive. The catch is packaging: your distribution’s NGINX is too old to have the directive, and its OpenSSL was built without the brotli algorithm that Chrome is the only browser to ask for. Measured, and with the one directive that stops NGINX from starting.

by Danila Vershinin,
Our RPM and DEB builds now link OpenSSL 3.5, so hybrid post-quantum key exchange with X25519MLKEM768 works out of the box on every platform we package for — from RHEL 8 to Ubuntu 20.04. Here is how to verify it, and the one common hardening directive that silently turns it off.

by Danila Vershinin, August 25, 2026
Server-side ECH (RFC 9849) is live in our stock NGINX, NGINX-MOD and EDGE packages, on RPM and DEB alike, built on OpenSSL 3.5 LTS with the DEfO backport. Here is what it hides, what it does not, and how to run it with automatic key rotation.

by Danila Vershinin, August 11, 2026
NGINX early hints support arrived in 1.29.0, but every stock Enterprise Linux, Debian and Ubuntu package still ships something older. We install a current NGINX from GetPageSpeed, configure the safe HTTP/2 gate, and benchmark what HTTP 103 does to LCP with interleaved arms and an A/A noise control.

by Danila Vershinin, August 6, 2026
Serve WP Rocket Cache Directly from Nginx Without PHP WP Rocket writes cached pages as static HTML files. On a typical Nginx setup, a request still passes through PHP-FPM before that cached file reaches the visitor. That extra hop is unnecessary. Nginx can locate and serve the existing WP Rocket cache file directly. PHP-FPM, WordPress, […]

by Danila Vershinin, August 3, 2026
CloudLinux is a good product. It is also a forked kernel you pay monthly to run on your own hardware. That is the whole conversation. When you install CloudLinux, you replace the in-tree AlmaLinux/RHEL kernel with theirs. From that day, every dnf upgrade, every kernel CVE, every security window is gated on their release cadence, […]

by Danila Vershinin, July 25, 2026
How NGINX variables really work: per-request containers, get handlers, lazy-and-cached map values, the empty-versus-not-found distinction, and subrequest isolation, with runnable, curl-verified examples using the echo, set-misc, lua, and array-var modules.
