Are there any widely used TLS libraries in Julia, even non pure ones?

The sockets API in stdlib is great but my use case isn’t over LAN so I need proper crypto and google searches don’t turn up an obvious choice for TLS.

Julia ships with MbedTLS. You can use the [Downloads](https://GitHub.com/JuliaLang/Downloads.jl) package on 1.3-1.5 to download things over HTTPS.

Ah that’s good to know. My use case is encrypting TCP traffic, so using the builtin MbedTLS looks like the way to go. The example code at [https://github.com/JuliaLang/MbedTLS.jl](https://github.com/JuliaLang/MbedTLS.jl) looks like exactly what I was looking for. Fantastic!

Thanks Stefan!
