To store passwords securely, they should be salted, then hashed with a slow hash function. This library uses PBKDF1-SHA256, and handles all the details. It uses the cryptohash package for speed; if you need a pure Haskell library, pwstore-purehaskell has the exact same API, but uses only pure Haskell. It is about 25 times slower than this package, but still quite usable.

This is a pretty printing library based on Wadler's paper A Prettier Printer. This version allows the library user to declare overlapping instances of the Pretty class.

__This package is deprecated__. Please, use genByteString from the [random package (version >=1.2)](https://hackage.haskell.org/package/random) instead. . Efficient generation of random bytestrings. The implementation populates uninitialized memory with uniformily distributed random 64 bit words (and 8 bit words for remaining bytes at the end of the bytestring). . Random words are generated using the PRNG from the [mwc-random](https://hackage.haskell.org/package/mwc-random) package or the [pcg-random](https://hackage.haskell.org/package/pcg-random) package. It is also possible to use a custom PRNG by providing an instance for the RandomWords type class and using the function generate from the module "Data.ByteString.Random.Internal". . The generated byte strings are suitable for statistical applications. They are /not/ suitable for cryptographic applications. .  . 

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

ByteString-backed Handles

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.

This library provides functions for parsing and pretty printing Roman numerals. Because the notation of Roman numerals has varied through the centuries this package allows for some customisation using a configuration that is passed to the conversion functions.

ghc-doctest-driver-gen is a Doctest's driver file generator. It lets you automatically generate driver file for Doctest's Cabal integration.

This package provides a Cairo vector graphics rendering backend for the Charts library.

SDL_mixer is a sample multi-channel audio mixer library. It supports any number of simultaneously playing channels of 16 bit stereo audio, plus a single channel of music, mixed by the popular MikMod MOD, Timidity MIDI, Ogg Vorbis, and SMPEG MP3 libraries.

Wrappers and helpers to bridge Haskell and <https://www.lua.org/ Lua>. . It builds upon the /lua/ package, which allows bundling a Lua interpreter with a Haskell program.

This library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

This package provides a newtype wrapper with FromJSON/ToJSON instances customisable via a phantom type parameter. The instances can be rendered to the original type using DerivingVia.

This package provides access to platform dependent file locking APIs. There are alternative file locking packages:

• GHC.IO.Handle.Lock in base >= 4.10 is good enough for most use cases. However, uses only Handles so these locks cannot be used for intra-process locking.

• ghc-filelock doesn't support OFD locking.

This Haskell package includes a thin sqlite3 wrapper based on the direct-sqlite package, as well as the entire C library, so there are no system dependencies.

Zstandard compression packaged as a conduit. This is a very thin wrapper around the official hs-zstd interface.

This package provides Type-level booleans.

This package defines classes of monads that can perform multiple executions in parallel and combine their results. For any monad that's an instance of the class, the package re-implements a subset of the Control.Monad interface, but with parallel execution.

This package converts between bytestrings and their hexadecimal string representation.

Haskell library for parsing of ISO 8601 dates, originally from aeson.

Lua module wrapping Text.DocLayout.

HAProxy protocol version 1.5 support (see http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt) for applications using io-streams. The proxy protocol allows information about a networked peer (like remote address and port) to be propagated through a forwarding proxy that is configured to speak this protocol.

This package contains a backend for ghc-persistent using the MySQL database server. Internally it uses the ghc-mysql-simple and mysql packages in order to access the database. This package supports only MySQL 5.1 and above. However, it has been tested only on MySQL 5.5. Only the InnoDB storage engine is officially supported.

This package provides an implementation of MurmurHash2, a good, fast, general-purpose, non-cryptographic hashing function. See https://sites.google.com/site/murmurhash/ for details. This implementation is pure Haskell, so it might be a bit slower than a C FFI binding.
