S2n-TLS – A C99 implementation of the TLS/SSL protocol
It seems to support multiple options but requires you pick at least one of them. https://github.com/aws/s2n-tls/blob/main/docs/BUILD.md#build...

OpenSSL 1.1.1 End of Life
I think GnuTLS is probably the second most popular TLS library, after openssl.
I'll also mentions s2n and rustls-ffi for completeness as C libraries, though the former isn't widely used, and the latter is very experimental still. https://github.com/aws/s2n-tls and https://github.com/rustls/rustls-ffi respectively.

I want XAES-256-GCM/11
I've seen operating on unauthenticated plaintext enough times to list it as my own pet peeve with AES-GCM. But it's a problem for chunked messages too. A few years ago we released a SCRAM mode that makes very minimal changes to AES-GCM so that it mathematically can't operate on unauthenticated plaintext. https://github.com/aws/s2n-tls/tree/main/scram

Golang is evil on shitty networks
> The documentation is kind of vague, but apparently you have to re-enable it regularly.[3]
This is correct. And in the end it means more or less that setting the socket option is more of a way of sending an explicit ACK from userspace than a real setting.
It's not great for common use-cases, because making userspace care about ACKs will obviously degrade efficiency (more syscalls).
However it can make sense for some use-cases. E.g. I saw the s2n TLS library using QUICKACK to avoid the TLS handshake being stuck [1]. Maybe also worthwhile to be set in some specific RPC scenarios where the server might not immediately send a response on receiving the request, and where the client could send additional frames (e.g. gRPC client side streaming, or in pipelined HTTP requests if the server would really process those in parallel and not just let them sit in socket buffers).

S2n-QUIC (Rust implementation of QUIC)
It looks like by default s2n-quic uses this TLS implementation, which is not based on the ring crate (though it is written in C)

LibreSSL Languishes on Linux
I would be interested in the other SSL implementations:
- https://github.com/awslabs/s2n
- https://boringssl.googlesource.com/boringssl
- https://bearssl.org/
Are these subpar implementations or there are other reasons not to use these?
