A collection of crypto hashes, with a practical incremental and one-pass, pure APIs, with performance close to the fastest implementations available in other languages. The implementations are made in C with a haskell FFI wrapper that hides the C implementation.

This Haskell package provides an incremental and one-pass, pure API to the SHA-1 hash algorithm, including HMAC support, with performance close to the fastest implementations available in other languages.

The implementation is made in C with a haskell FFI wrapper that hides the C implementation.

This module provides Haskell bindings and extensions to the curve25519-donna codebase. It's a pretty straightforward implementation of the basic cryptographic routines you'd want from a project that uses curve25519: key generation, and key agreement. For further functionality, you'll want to look elsewhere.

This package provides a simple monadic parser for ASN1 stream types, when ASN1 pattern matching is not convenient.

This package provides a reader and writer for ASN1 data in raw form with supports for high level forms of ASN1 (BER, and DER).

This library provides functions to read and write X509 certificates.

This Haskell package provides AES cipher implementation.

The modes of operations available are ECB (Electronic code book), CBC (Cipher block chaining), CTR (Counter), XTS (XEX with ciphertext stealing), GCM (Galois Counter Mode).

The AES implementation uses AES-NI when available (on x86 and x86-64 architecture), but fallback gracefully to a software C implementation.

The software implementation uses S-Boxes, which might suffer for cache timing issues. However do notes that most other known software implementations, including very popular one (openssl, gnutls) also uses similar implementation. If it matters for your case, you should make sure you have AES-NI available, or you'll need to use a different implementation.

This package provides a library for looking up and validating HTML5 entities. The following document is used as an authoritative source of the valid entity names and their corresponding codepoints. You can think of this library as about bindings to the data from that file. For usage see the Text.Html5.Entity module.

This package provides a static file serving subsite for the Yesod Web Framework.

This package's main goal is to encourage integration and system testing of web applications by making everything easy to test. Tests are like browser sessions that keep track of cookies and the last visited page. You can perform assertions on the content of HTML responses using CSS selectors.

Warp is a server library for HTTP/1.x and HTTP/2 based WAI (Web Application Interface in Haskell).

This package bundles the minified jQuery code into a Haskell package, so it can be depended upon by Cabal packages. The first three components of the version number match the upstream jQuery version. The package is designed to meet the redistribution requirements of downstream users (e.g. Debian).

This library provides basic MIME type handling types and functions.

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.

HTTP cookie parsing and rendering library for Haskell.

Scalpel core provides a subset of the scalpel web scraping library that is intended to have lightweight dependencies and to be free of all non-Haskell dependencies.

The Haskell package package groups together the various Yesod related packages into one cohesive whole. This is the version of Yesod, whereas most of the core code lives in ghc-yesod-core.

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 web server promotes a function from Request to IO Response into a local web server. The user can decide how to interpret the requests, and the library is intended for implementing Ajax APIs.

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

This package provides a JSON pretty-printing library compatible with aeson as well as a command-line tool to improve readability of streams of JSON data. The library provides the function encodePretty. It is a drop-in replacement for aeson's encode function, producing JSON-ByteStrings for human readers. The command-line tool reads JSON from stdin and writes prettified JSON to stdout. It also offers a complementary "compact"-mode, essentially the opposite of pretty-printing.

This Haskell package provides a set of basic form inputs such as text, number, time, checkbox, select, textarea, etc through the Yesod.Form.Fields module. Also, there is Yesod.Form.Nic module providing richtext field using Nic editor.

Skein is a family of fast secure cryptographic hash functions designed by Niels Ferguson, Stefan Lucks, Bruce Schneier, Doug Whiting, Mihir Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker.

This Haskell package uses bindings to the optimized C implementation of Skein.

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.
