  • Struggling with the OpenSSL Crate

    Beyond that, various things like the ScyllaDB driver are using OpenSSL because WebPKI doesn't support validating connections to IP addresses (as opposed to DNS names) and RusTLS currently delegates to WebPKI.
  • What Is Rust's Hole Purpose?

    There's a JIT framework in Rust: https://github.com/bytecodealliance/wasmtime

    There's a library for doing full X.509 certificate parsing and verification: https://briansmith.org/rustdoc/webpki/

    There's definitely some attempts at doing pure-Rust SSL, but I suspect a lot of them are also doing some sketchy things with crypto that shouldn't be trusted (getting constant-time stuff implemented properly is really challenging, and probably requires large amounts of assembly to guarantee correctness).

  • I think a major issue with the rust ecosystem is that it's full of unexpected design decisions

    An issue was raised with webpki to support the IP addressees 5 years ago, and yet it's still not there. What do people use to overcome the fact that rustls can't do IP-based client connections because of it? My guess would be, they are switching to native-tls or openssl-tls.

    Yes, rustls currently doesn't support certificates without hostnames (only an IP); this is actually an issue with the webpki crate, and work to solve it is ongoing (will hopefully land in a release in a few months or so).

    > Bundling this set with Firefox

    I love that they did that; it was actually my idea (https://bugzilla.mozilla.org/show_bug.cgi?id=657228). I believe the list is pretty large and changes frequently and so they download it dynamically.

    Do they really do that? That's awesome if so. Then they don't even need to ship the roots.

    > I specifically don't like [...] saying "unknown issuer"


    > If std::fs::File::open() gives me Result with an io:Error that claims "File not found" but the underlying OS file open actually failed due to a permission error, you can see why that's a problem right? Even if this hypothetical OS doesn't expose any specific errors, "File not found" is misleading.

    A more accurate analogy: You ask to open "example.txt" without supplying the path, and there is no "example.txt" in the current working directory. You will get "file not found."

    Regardless, I agree we could have a better name than UnknownIssuer for this error.

    > he situation described above just generated an "Invalid certificate" message. More use of anyhow::Context would be helpful. I don't disagree with Rustls disallowing decade-obsolete crypto. It's the "silently ignores" part that's a problem.

    Because of how X.509 certificate validation works, in general it's not possible to tell you why an issuer couldn't be found, because there are many possible reasons.

    Regardless https://github.com/briansmith/webpki/issues/206 tracks improving the situation.
