      HardenedBSD had to switch back to OpenSSL from LibreSSL a few years back. I’d love it if HardenedBSD’s community came together to re-add LibreSSL as the default crypto lib in base. But, that work is especially daunting when you consider you also have to maintain/fix the resulting breakages for over 30,000 packages.

        Very interesting. That does all sound very worrying for anyone relying on OpenSSL going forward.

        It’s frustrating that FIPS mode could be the deal-breaker, I hope they find a way to make that work.

        1. 3

          Kinda tangential, but is FIPS strictly a US thing? I’ve never heard of it outside of that, but then again I hadn’t heard about FIPS for a very long time in general.

          1. 3

            Yes, it’s “Federal Information Processing Standards” as in US Federal.

            1. 2

              My understanding is that FIPS requires some ciphersuites that the LibreSSL project deems weak or insecure and thus won’t include.

              I’m not part of the Alpine project, but I wonder how much would be “lost” by declaring Alpine non-FIPS compliant. It would suck for the poor saps required to use FIPS but surely there are alternatives.

              1. 10

                FIPS also, if I remember correctly, requires that the specific build be certified, so you can’t even just build your own version of OpenSSL and have it FIPS compliant, you need to ship a blob that has gone through the certification process. OpenSSL has some dynamic loading goo that lets you plug in a FIPS-complaint module, it doesn’t provide that module (it did briefly but now it’s purely a third-party thing). My understanding is that ‘FIPS Compliant’ is a synonym for ‘definitely insecure but not my liability when you’re compromised’ but I might be overly cynical.

                1. 5

                  Correct. Here is a summary for it: https://www.openssl.org/docs/fips.html (with a link to the 3.0 version). It’s not so much insecure as “very conservative”. I’m not aware of the certified version being vulnerable and the public API gets updated/fixed with openssl.

                  1. 1

                    Thanks for the clarification!

              2. 0

                That is true and also useless information, because I probably wouldn’t have asked if I hadn’t known what it stands for.

                The NIST curves are also “from the US”, so is FIPS 10, and they have leaked into global usage (and the latter is a mess).

          2. 2

            promoting libtls makes it easier to eventually fully switch to BearSSL, via @michaelforney’s libtls-bearssl

            hmm! Yeah this is interesting. It would be cool to have a libtls-rustls as well. Is there a good test suite for the libtls API?
