There's a JIT framework in Rust: https://github.com/bytecodealliance/wasmtime https://github.com/bytecodealliance/wasmtime There's a library for doing full X.509 certificate parsing and verification: https://briansmith.org/rustdoc/webpki/ 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).
