# Pbkdf2
[![Hex.pm Version](http://img.shields.io/hexpm/v/pbkdf2_elixir.svg)](https://hex.pm/packages/pbkdf2_elixir)
[![Build Status](https://travis-ci.com/riverrun/pbkdf2_elixir.svg?branch=master)](https://travis-ci.com/riverrun/pbkdf2_elixir)
Pbkdf2 password hashing library for Elixir.
Pbkdf2 is a well-tested password-based key derivation function that can be
configured to remain slow and resistant to brute-force attacks even as
computational power increases.
## Comparison with the Plug.Crypto version of Pbkdf2
If you want the Pbkdf2 output to be in binary (raw) or hex format, you might
find [Plug.Crypto.KeyGenerator](https://hexdocs.pm/plug_crypto/Plug.Crypto.KeyGenerator.html)
more convenient.
## Installation
1. Add pbkdf2_elixir to the `deps` section of your mix.exs file:
```elixir
def deps do
[
{:pbkdf2_elixir, "~> 1.3"}
]
end
```
2. Optional: during tests (and tests only), you may want to reduce the number of rounds
so it does not slow down your test suite. If you have a config/test.exs, you should
add:
```elixir
config :pbkdf2_elixir, :rounds, 1
```
