## Motivation

AES has removed the block size of 256 bits from the standard and if a old system is using it AES willn't work (my case) and there's no Rijndael implementations in Erlang or Elixir.

## Installation

**Warning:** You will need the [Rust compiler](https://www.rust-lang.org/tools/install) to compile this package.

This package has been published in [Hex.pm](https://hex.pm/packages/simple_rijndael) and you can use it with:

```elixir

def deps do

  [

    {:simple_rijndael, "~> 0.1.0"}

  ]

end

```

## Usage

```elixir

key = :crypto.strong_rand_bytes(32)

iv = :crypto.strong_rand_bytes(32)

# Padding options:

#   :pkcs7

#   :zero

{:ok, cipher} = SimpleRijndael.init_cbc_mode(key, 32, :pkcs7)

data = "Hello, World!"

{:ok, encrypted} = SimpleRijndael.encrypt(cipher, iv, data)

{:ok, decrypted} = SimpleRijndael.decrypt(cipher, iv, encrypted)

# If an error occour, will be one of the following returns:

#   {:error, :invalid_data_size}

#   {:error, :invalid_key_size}

#   {:error, :invalid_block_size}

#

# Or an exception of ErlangError with reason == nil and original == :nif_panicked

```
