The package provides the standard types for dealing with the ASN.1 format.

This package provides tools for operating system dependent X.509 stores, storage methods, and accessors.

This library contains io-streams routines for secure networking using OpenSSL (by way of HsOpenSSL).

HsOpenSSL is an OpenSSL binding for Haskell. It can generate RSA and DSA keys, read and write PEM files, generate message digests, sign and verify messages, encrypt and decrypt messages. It has also some capabilities of creating SSL clients and servers. This package is in production use by a number of Haskell based systems and stable. You may also be interested in the tls package, http://hackage.haskell.org/package/tls, which is a pure Haskell implementation of SSL.

This package provides generic X509 support for Haskell.

This library provides functions to read and write X509 certificates.

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

This library provides readers and writers for the Privacy Enhanced Mail (PEM) format.

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

Library for Parsing and formatting HTTP Date in Haskell.

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 Unicode encoding and decoding functions for encodings used in the Haskell XML Toolbox. ISO Latin 1-16, utf8, utf16, ASCII are supported. Decoding is done with lazy functions, errors may be detected or ignored.

The Haskell XML Toolbox bases on the ideas of HaXml and HXML, but introduces a more general approach for processing XML with Haskell.

This library provides sanitizeXSS. Run untrusted HTML through Text.HTML.SanitizeXSS.sanitizeXSS to prevent XSS attacks.

This extension for the Haskell XML Toolbox defines data types to represent XPath, navigation trees and primitives to select and edit subtrees from them. Some primitives have both a functional and an arrow interface.

This package handles cross-platform Web browser launching and inserts JavaScript code to ping the server. When the server no longer receives pings, it shuts down.

This package provides a parser for HTML documents that uses tagstream-conduit. It automatically balances mismatched tags, so that there shouldn't be any parse failures. It does not handle a full HTML document rendering, such as adding missing html and head tags. Note that, since version 1.3.1, it uses an inlined copy of tagstream-conduit with entity decoding bugfixes applied.

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.

Use websockets with WAI applications, primarily those hosted via Warp.

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 data streaming abstraction for Haskell's Web Application Interface (WAI).

HTTP multipart split out of the cgi package, for Haskell.

This library provides basic WAI handlers and middleware functionality.

aeson-qq provides a JSON quasiquoter for Haskell. This package exposes the function aesonQQ that compile-time converts a string representation of a JSON value into a Data.Aeson.Value.
