One stop solution for tcp client and server with tls support!
-
use io-streams for auto read buffering and easy streamming process.
-
use tls for tls connection.
Built-in mozilla CA list date: 2017/06/07.
From v0.6 TLS using HsOpenSSL is split into tcp-streams-openssl due to the difficulties of setting up openssl on many platform.
Also take a look at wire-stream, for serialize/deserialize data. Happy hacking!
