tcp-streams

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: 2016/11/02.

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!

Example

import qualified System.IO.Streams         as Stream
import qualified System.IO.Streams.TCP     as TCP
import qualified Data.TLSSetting           as TLS
import qualified System.IO.Streams.TLS     as TLS

--  TCP Client
...
(is, os, sock) <- TCP.connect "127.0.0.1" 8888
Stream.write os =<< ..  -- sending
Stream.read is >>=  ..  -- receiving
TCP.close sock   ..  -- closing
...


-- TCP Server
...
sock <- TCP.bindAndListen 8888 1024
(is, os, csock, _) <- TCP.accept sock
Stream.write os =<< ..  -- sending
Stream.read is >>= ..   -- receiving
...


--  TLS Client
...
cp <- TLS.makeTLSClientParams (TLS.CustomCAStore "myCA.pem")
(is, os, ctx) <- TCP.connect cp (Just "myCAName") "127.0.0.1" 8888
Stream.write os =<< ..  -- sending
Stream.read is >>=  ..  -- receiving
TLS.close ctx    ..  -- closing
...


--  TLS Server
...
sp <- TLS.makeServerParams "server.crt" [] "server.key"
sock <- TCP.bindAndListen 8889 1024
(is, os, ctx, sockAddr) <- TLS.accept sp sock
Stream.write os =<< ..  -- sending
Stream.read is >>= ..   -- receiving
...


-- HTTPS Client
...
cp <- TLS.makeClientParams TLS.MozillaCAStore
(is, os, ctx) <- TLS.connect cp Nothing "www.google.com" 443
Stream.write (Just "GET / HTTP/1.1\r\n") os
Stream.write (Just "Host: www.google.com\r\n") os
Stream.write (Just "\r\n") os
bs <- Stream.readExactly 1024 is
