OpenSSL 4.1.0

What HN thinks

A release-notes thread that spent half its time mourning Itanium and the other half relitigating OpenSSL 3.0's speed.

3.x performance regressions still sting
Commenters note OpenSSL 3.x remains much slower than 1.1.1 in places like key parsing, though maintainers point to real improvements in 4.1 and more planned for 4.2.
Overengineering, not malice
A debate over whether OpenSSL's convoluted APIs hide exploitability; most argue it's ordinary overengineering, while others cite OpenBSD's Heartbleed-era audit as damning.
Farewell Itanium and Windows CE
Dropping old Windows targets prompted nostalgia and tangents about legacy platforms and Microsoft's compatibility burden.

Consensus: Most agree OpenSSL's complexity and 3.x slowdowns are real problems, though many find the current performance acceptable for typical TLS termination; new DTLS 1.3 support was welcomed.

Recommended in the comments

AWS-LC (library): Suggested as a promising faster replacement for OpenSSL.
LibreSSL ↗ (library): Raised as a cleaner alternative that has supported TLS 1.3 since 2020.
wolfSSL (library): Used for DTLS 1.3 and tested as an OpenSSL alternative.
BoringSSL (library): Mentioned as having supported features like GREASE long before OpenSSL.
