tls: report negotiated TLS groups by panva · Pull Request #64119 · nodejs/node

panva · 2026-06-24T22:22:06Z

tlsSocket.getEphemeralKeyInfo() currently returns an empty object for TLS 1.3 key agreement groups where OpenSSL does not expose a peer temporary key object, including ML-KEM and hybrid ML-KEM groups.

This updates the shared TLS helper to fall back to OpenSSL's negotiated TLS group name and return { type: 'TLSGroup', name: '<group>' }.

The existing DH and ECDH result shapes are unchanged and still take precedence when OpenSSL provides a recognizable temporary key. TLSGroup does not include size, because Node cannot derive a meaningful single key size for PQ or hybrid groups.

The TLS docs now describe TLSGroup, point users to the IANA TLS Supported Groups registry, and clarify that the historical ecdhCurve option also configures TLS Supported Groups for TLS 1.3.

Fixes: #59452

When OpenSSL reports no peer temporary key object for TLS key agreement, fall back to the negotiated TLS Supported Group name. This lets getEphemeralKeyInfo() identify PQ, hybrid, and other group-based key agreement as TLSGroup without synthesizing a size. Keep existing DH and ECDH results unchanged when OpenSSL provides a recognizable temporary key. Fixes: nodejs#59452 Signed-off-by: Filip Skokan <panva.ip@gmail.com>

When OpenSSL reports no peer temporary key object for TLS key agreement, fall back to the negotiated TLS Supported Group name. This lets getEphemeralKeyInfo() identify PQ, hybrid, and other group-based key agreement as TLSGroup without synthesizing a size. Keep existing DH and ECDH results unchanged when OpenSSL provides a recognizable temporary key.

Highlights include the Temporal API enabled by default, updates to the V8 JavaScript engine to 14.6, Undici to 8.0, and several important deprecations and removals as we continue to modernize the platform. As a reminder, Node.js 26 will enter long-term support (LTS) in October, but until then, it will be the "Current" release for the next six months. We encourage you to explore the new features and benefits offered by this latest release and evaluate their potential impact on your applications. ### Notable Changes #### Temporal API The Temporal API is now enabled by default in Node.js 26. Temporal is a modern date/time API for JavaScript that provides a more robust and feature-rich alternative to the legacy `Date` object. Contributed by Richard Lau in [#61806](nodejs/node#61806). #### V8 14.6 The V8 engine is updated to version 14.6.202.33, which is part of Chromium 134. This version also includes: * Upsert (<https://github.com/tc39/proposal-upsert>): `[Weak]Map.prototype.getOrInsert()`, `[Weak]Map.prototype.getOrInsertComputed()` * Iterator sequencing (<https://github.com/tc39/proposal-iterator-sequencing>): `Iterator.concat()` Contributed by Michaël Zasso in [#61898](nodejs/node#61898). #### Undici 8 Undici has been updated to version 8.0.2, bringing new features and improvements to Node.js's HTTP client implementation. #### Deprecations and Removals * \[[`dff46c07c3`](nodejs/node@dff46c07c3)] - **(SEMVER-MAJOR)** **crypto**: move DEP0182 to End-of-Life (Tobias Nießen) [#61084](nodejs/node#61084) * \[[`93c25815ee`](nodejs/node@93c25815ee)] - **(SEMVER-MAJOR)** **http**: move writeHeader to end-of-life (Sebastian Beltran) [#60635](nodejs/node#60635) `http.Server.prototype.writeHeader()` is now fully removed. Use `http.Server.prototype.write… (truncated) ### v26.1.0 ### Notable Changes #### Experimental `node:ffi` module Node.js now includes an experimental `node:ffi` module for loading dynamic libraries and calling native symbols from JavaScript. The API is gated behind the `--experimental-ffi` flag and, when the Permission Model is enabled, requires `--allow-ffi`. This API is inherently unsafe. Invalid pointers, incorrect signatures, or accessing memory after it has been freed can crash the process or corrupt memory.

This change serves to communicate that risk. At present, our intention remains to continue shipping universal binaries supporting both Apple Silicon and Intel-based Macs for as long as practical.
