Blake3
Elixir bindings for the Rust Blake3 implementation.
These bindings use :rustler
to connect to the hashing functions.
Installation
The package can be installed by adding blake3
to your list of dependencies in mix.exs
:
def deps do
[
{:blake3, "~> 1.0"}
]
end
run mix deps.get
and mix deps.compile
to pull and build the bindings
Configuration
There are feature options in the rust implementation that allow for additional SIMD instructions and multithreading. They can be set though environment variable or Mix.Config
.
export BLAKE3_SIMD_MODE=neon
export BLAKE3_RAYON=true
or
config :blake3,
simd_mode: :neon,
rayon: :true
-
neon
enables ARM NEON support -
rayon
enables Rayon-based multithreading
When changing configuration you will need to call mix deps.compile
to enable the features.
Example Usage
> Blake3.hash("foobarbaz")
#<<192, 154, 254, 224, 201, 243, 97 ...
> Blake3.new() |> Blake3.update("foo") |> Blake3.update("bar") |> Blake3.update("baz") |> Blake3.finalize()
#<<192, 154, 254, 224, 201, 243, 97 ...
> Blake3.hash("boom") |> Base.encode16(case: :lower)
