That sucks. It's integrated fairly deeply with the Zephyr ecosystem and I'm working on several products that use it, some of them fresly migrated to it...

I've made a PR a while back to add support for authenticated attributes and chain certificates (https://github.com/Mbed-TLS/mbedtls/pull/10232), turns out there are several open PRs for that feature set over the years and they just all sit there. That doesn't inspire contributors to stick around.

That's nonsense. I've been using MbedTLS for years now in lots of FLOSS projects, and it's biggest mistake was forcing that terrible and buggy PSA API (a mandatory git module in MbedTLS which does not even compile without dirty hacks (*)).

Now they are saying that MbedTLS is going to be discontinued and only the shitty PSA remains? They have lost their minds, time to look for another Open Source alternative, I'm afraid. :-(

(*) - after days of debugging, I've found that an uninitalized variable bug in psa_crypto_mac.c prevents my https client to download files from codeberg. I had to apply a patch to make it work: https://codeberg.org/bzt/ludus/src/branch/main/src/lib/mbedt... That's how "great" PSA is.

What surprised me in the comments are people who use the software for their work who are complaining that they won't be getting updates for free on an Open Source project. People used to pay $$$ to buy licenses to libraries like this... People have a weird understanding of how Open Source works.

Damn. We just migrated to Mbed TLS for a native app at my work, only this year. I hope some folks with cryptographic chops will step up. It's really a pleasant library use - we were previously using CryptoPP, shudder.

This will put a huge amount of projects into trouble, so I'm confident the community will come up with a solution.

But here's one thing I'm wondering: with LLMs being now super-human when it comes to algorithms and computer code, wouldn't it be possible to set up a "project super-harness" for a TLS client library for (not necessarily mbedTLS main branch!!), put up a constant "pool budget" between various individuals and organizations, and let the LLMs care for ongoing maintenance?

Tbh now with the ai you can generate a pretty good tls library in like a day especially if supporting only the latest tls revision is good enough.
