This package provides a native Haskell TLS and SSL protocol implementation for server and client. It provides a high-level implementation of a sensitive security protocol, eliminating a common set of security issues through the use of the advanced type system, high level constructions and common Haskell features. It currently implements the SSL3.0, TLS1.0, TLS1.1 and TLS1.2 protocol, and supports RSA and Ephemeral (Elliptic curve and regular) Diffie Hellman key exchanges, and many extensions.

This package provides a Haskell-only implementation of the MD5 digest (hash) algorithm. This now supports the crypto-api class interface.

This package provides generic X509 support for Haskell.

This package provides functions for X.509 certificate and revocation list validation.

This Haskell package provides implementation of MD5.

This library provides functions to read and write X509 certificates.

This library implements the SHA suite of message digest functions, according to NIST FIPS 180-2 (with the SHA-224 addendum), as well as the SHA-based HMAC routines. The functions have been tested against most of the NIST and RFC test vectors for the various functions. While some attention has been paid to performance, these do not presently reach the speed of well-tuned libraries, like OpenSSL.

This package provides a cross-platform library that tries to find a (reasonable) CA certificate bundle that can be used with HsOpenSSL to verify the certificates of remote peers. It is for HsOpenSSL what x509-system is for the tls package, and borrows some ideas from x509-system.

Happstack Server provides an HTTP server and a rich set of functions for routing requests, handling query parameters, generating responses, working with cookies, serving files, and more.

This package provides a library for the Web Distributed Authoring and Versioning (WebDAV) extensions to HTTP as well an executable, hdav, for command-line operation.

This package provides the logging system for WAI.

This library allows you to write WebSocket-capable servers.

An example server: https://github.com/jaspervdj/websockets/blob/master/example/server.lhs An example client: https://github.com/jaspervdj/websockets/blob/master/example/client.hs

Gives you the tools to build parsers to decode JSON values, and gives good error messages when parsing fails. See also http://harry.garrood.me/blog/aeson-better-errors/.

This package provides a Web Application Interface (WAI) library for the Haskell language. It defines a common protocol for communication between web applications and web servers.

This package provides a CSS parser and renderer for Haskell.

This Haskell library contains functions for encoding bytestring builders for chunked Hypertext Transfer Protocol (HTTP) 1.1 transfers.

This is a library for working with URIs in Haskell as per RFC 3986.

This library supports full W3C XML Schema regular expressions inclusive all Unicode character sets and blocks. It is implemented by the technique of derivations of regular expressions.

This package provides an HTTP client engine, intended as a base layer for more user-friendly packages.

This library provides tools reduce the size of JavaScript files by stripping out extraneous whitespace and other syntactic elements, without changing the semantics.

This Haskell package provides all core functionality, for Yesod, on which other packages can be built. It provides dispatch, handler functions, widgets, etc.

The HTTP package supports client-side web programming in Haskell. It lets you set up HTTP connections, transmitting requests and processing the responses coming back.

Base types used by a variety of HTTP clients and servers. See http-streams Network.Http.Client or pipes-http Pipes.Http.Client for full documentation. You can import Network.Http.Types if you like, but both http-streams and pipes-http re-export this package's types and functions.

This package provides a JSON parsing and encoding library for Haskell, optimized for ease of use and high performance. (A note on naming: in Greek mythology, Aeson was the father of Jason.)
