    Being able to use rustls as a drop-in replacement for openssl is on their roadmap: https://github.com/rustls/rustls/blob/main/ROADMAP.md#future...

    So that'll certainly one option in the future.

  • 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!

    > 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.

    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.

    Then you also might need to use rustls , some kind of oauth crate and a persistence layer of choice (database).
