lowlevel set of cryptographic primitives for haskell

Cryptonite is a haskell repository of cryptographic primitives. Each crypto algorithm has specificities that are hard to wrap in common APIs and types, so instead of trying to provide a common ground for algorithms, this package provides a non-consistent low-level API.

If you have no idea what you're doing, please do not use this directly. Instead, rely on higher level protocols or implementations.

Development versions are an incremental number prefixed by 0. There is no API stability between development versions.

Production versions : TBD

Coding Style

The coding style of this project mostly follows: haskell-style


cryptonite supports the following platforms:

  • Windows >= 8
  • OSX >= 10.8
  • Linux
  • BSDs

On the following architectures:

  • x86-64
  • i386

On the following haskell versions:

  • GHC 7.0.x
  • GHC 7.4.x
  • GHC 7.6.x
  • GHC 7.8.x
  • GHC 7.10.x

Further platforms and architectures probably work too, but since the maintainer(s) don't have regular access to them, we can't commit to further support.

Known Building Issues

On OSX <= 10.7, the system compiler doesn't understand the '-maes' option, and with the lack of autodetection feature builtin in .cabal file, it is left on the user to disable the aesni. See the [Disabling AESNI] section

Disabling AESNI

It may be useful to disable AESNI for building, testing or runtime purposes. This is achieved with the support_aesni flag.

As part of configure of cryptonite:

  cabal configure --flag='-support_aesni'

or as part of an installation:

  cabal install --constraint="cryptonite -support_aesni"
