Keccak-f[1600] NIF (SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, SHAKE256)

Build Status Hex.pm

Keccak-f[1600] NIF with timeslice reductions for Erlang and Elixir.

The timeslice reductions allow the NIF to perform operations on very large inputs without blocking the scheduler or requiring the Erlang VM to support dirty schedulers. See the bitwise project from which the strategy was derived.

Tested against the FIPS 202 test vectors.

Installation

Add keccakf1600 to your project's dependencies in mix.exs

defp deps do
  [
    {:keccakf1600, "~> 2.0.0"}
  ]
end

Add keccakf1600 to your project's dependencies in your Makefile for erlang.mk or the following to your rebar.config

{deps, [
  {keccakf1600, ".*", {git, "git://github.com/potatosalad/erlang-keccakf1600.git", {branch, "master"}}}
]}.

Usage

This library follows usage semantics from Erlang's own crypto library, with the exception of the SHAKE128 and SHAKE256 algorithms as described in keccakf1600:hash/3 and keccakf1600:final/2 below.

keccakf1600:hash/2

This function can be used for the following algorithms:

  • SHA3-224 (sha3_224)
  • SHA3-256 (sha3_256)
  • SHA3-384 (sha3_384)
  • SHA3-512 (sha3_512)

keccakf1600:hash/3

This function can be used for the following algorithms:

  • SHAKE128 (shake128)
  • SHAKE256 (shake256)

These algorithms can output arbitrary length digests, so an output length must be specified.

keccakf1600:final/3

This function can be used for the following algorithms:

  • SHA3-224 (sha3_224)
  • SHA3-256 (sha3_256)
  • SHA3-384 (sha3_384)
  • SHA3-512 (sha3_512)

These algorithms can output arbitrary length digests, so an output length must be specified.

The examples below use the Sponge1 for each algorithm from the examples above for keccakf1600:update/2.

SHAKE128 (shake128)

Out = keccakf1600:final(Sponge1, 16).
% <<211,176,170,156,216,183,37,86,34,206,188,99,30,134,125,64>>

SHAKE256 (shake256)

Out = keccakf1600:final(Sponge1, 16).
% <<181,79,247,37,87,5,167,30,226,146,94,74,62,48,228,26>>
