Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
rustls
- Pingora: HTTP Server and Proxy Library, in Rust, by Cloudflare, Released
- Alternative to openssl for reqwest https with client certs.
- rustls 0.22 is out with pluggable crypto providers and better CRL support

Exploring the Rust compiler benchmark suite
The RustTLS project is currently setting up their own CI benchmarking workflow, so I think that you could find some inspiration there: https://github.com/rustls/rustls/issues/1385 and https://github.com/rustls/rustls/issues/1205.

What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?
I also studied this question on FFI several weeks ago in terms of "rewrite part of the system in Rust". Unexpected results could be semantic issues (e.g., different error handling methods) or security issues (FFI could be a soundness hole). I suggest going through the issues of libraries that have started rewriting work such as rust-openssl or rustls (This is the one trying to rewrite in whole rust rather than using FFI; however, you will not be able to find the mapping function in the C version and compare them). I hope this helps!

A brief guide to choosing TLS crates
Now for rust implementation of tls. Certificates can be loaded in two ways. * Finds and loads certificates using OS specific tools3 * Uses a rust implementation of webpki4 for loading with certificates5

Microsoft is busy rewriting core Windows library code in memory-safe Rust
> Ring is mostly C/Assembly
Crypto needs to be written in Assembly to ensure that operations take a constant time, regardless of input. Writing it in a high level language like C or Rust opens you up to the compiler "optimising" routines and making them no longer constant time.
But you already knew this. And you also knew that the security audit (https://github.com/rustls/rustls/blob/master/audit/TLS-01-re...) of ring was favourable
> No issues were found with regards to the cryptographic engineering of rustls or its underlying ring library. A recommendation is provided in TLS-01-001 to optionally supplement the already solid cryptographic library with another cryptographic provider (EverCrypt) with an added benefit of formally verified cryptographic primitives. Overall, it is very clear that the developers of rustls have an extensive knowledge on how to correctly implement the TLS stack whilst avoiding the common pitfalls that surround the TLS ecosystem. This knowledge has translated reliably into an implementation of exceptional quality.

> a standard library with feature flags and editions would make rust ridiculously much more productive
What's the difference between opting into a library with a feature flag and opting in with a line in Cargo.toml? Let's say you want to use the de-facto regex library. Would it really be ridiculously productive if you said you wanted the "regex" feature flag instead of the "regex" crate?
I do agree that the standard library does need a versioning story so they can remove long deprecated functions. Where it gets complicated is if a new method is reintroduced using the same name in a later edition.

gRPC with mutual TLS on IPs only
I used the commands listed in the .sh file here: https://github.com/rustls/rustls/tree/main/test-ca to generate keys/certs for a server and a client (with IP.1 records for SANs). I have added the local root CA to the trust store of each VM.

rustls 0.21 released with support for IP address server names
This is great news, this was our single biggest annoyance with rustls. One of our cloud providers choses to issue their hosted postgres instances with TLS certificates with IP addresses. Unusual, but valid per the spec, so why not. Apparently a practise that's also popular in kubernetes settings, so I'm somewhat surprised it took 5 years to close the issue, but now I can finally recommend people to use rustls without mentioning any gotchas.

Is Rust really safe? How to identify functions that can potentially cause panic
I believe it is more relevant than you think: servers running in containers, web assembler tasks running in browsers, embedded devices and kernels with total control of the system, all have the ability to do something more sensible than plain out SIGABRT or similar, and in many the case is not that the complete system is falling down. For example RustTLS is looking into allowing fallible allocators and as a pretty general-purpose library that seems like a nice feature. I do wish ulimit -v worked in a sensible manner with applications.

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.
-
Why is SSL such a pain?
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).

Preparing Rustls for Wider Adoption
> 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.
> short cut to a "Yes"
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"
https://github.com/briansmith/webpki/issues/221
> 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.
