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

Native Haskell TLS and SSL protocol implementation for server and client. This 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. Currently implement the SSL3.0, TLS1.0, TLS1.1 and TLS1.2 protocol, and support RSA and Ephemeral (Elliptic curve and regular) Diffie Hellman key exchanges, and many extensions.

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

This library provides functions to read and write X509 certificates.

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

This package provides a repository of cryptographic primitives.

• Symmetric ciphers: AES, DES, 3DES, CAST5, Blowfish, Twofish, Camellia, RC4, Salsa, XSalsa, ChaCha.

• Hash: SHA1, SHA2, SHA3, SHAKE, MD2, MD4, MD5, Keccak, Skein, Ripemd, Tiger, Whirlpool, Blake2.

• MAC: HMAC, KMAC, Poly1305

• Asymmetric crypto: DSA, RSA, DH, ECDH, ECDSA, ECC, Curve25519, Curve448, Ed25519, Ed448

• Key Derivation Function: PBKDF2, Scrypt, HKDF, Argon2, BCrypt, BCryptPBKDF

• Cryptographic Random generation: System Entropy, Deterministic Random Generator

• Data related: Anti-Forensic Information Splitter (AFIS)

This Haskell package provides implementation of MD5.

This package is a repository of cryptographic primitives for Haskell. It supports a wide range of symmetric ciphers, cryptographic hash functions, public key algorithms, key derivation numbers, cryptographic random number generators, and more.

This package provides efficient cryptographic hash implementations for strict and lazy bytestrings. For now, CRC32 and Adler32 are supported; they are implemented as FFI bindings to efficient code from zlib.

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 library provides HTML combinators for Haskell.

The modules provided by this package contain predicates for Unicode blocks and char properties and character predicates defined by XML. The supported Unicode version is 7.0.0

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

An HTTP client using the Snap Framework's io-streams library to handle the streaming IO. The API is optimized for ease of use for the rather common case of code needing to query web services and deal with the result.

This package provides SSL/TLS support for Warp, a WAI handler, via the native Haskell TLS implementation.

Provides a simple means of reverse-proxying HTTP requests. The raw approach uses the same technique as leveraged by keter, whereas the WAI approach performs full request/response parsing via WAI and http-conduit.

This library uses attoparsec for parsing the actual contents of the HTTP connection. It also provides higher-level functions which allow you to avoid direct usage of conduits.

This package provides generic HTTP types for Haskell (for both client and server code).

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.)

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.

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 a CSS parser and renderer for Haskell.

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

This Haskell package provides helpers for using Persistent from Yesod.
