Bcrypt

Bcrypt password hashing library for Elixir.

Bcrypt 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.

Compatibility with other Bcrypt libraries

This version is based on the OpenBSD version of Bcrypt and supports the $2b$ and $2a$ prefixes. For advice on how to use hashes with the $2y$ prefix, see this issue.

Installation

1. Add :bcrypt_elixir to the deps section of your mix.exs file:

   If you are using Erlang >20:

   def deps do
     [
       {:bcrypt_elixir, "~> 3.0"}
     ]
   end

   If you are using Erlang 19 or below:

   def deps do
     [
       {:bcrypt_elixir, "~> 0.12"}
     ]
   end

2. Make sure you have a C compiler installed. See the Comeonin wiki for details.

3. 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:

   config :bcrypt_elixir, :log_rounds, 4
