anoskov / aes-ctr-ex

AES cipher in CTR mode implementation using Elixir

AES CTR

AES cipher in CTR mode.

Installation

If available in Hex, the package can be installed as:

• Add aes_ctr to your list of dependencies in mix.exs:

def deps do
  [{:aes_ctr, "~> 0.1.0"}]
end

• Ensure aes_ctr_ex is started before your application:

def application do
  [applications: [:aes_ctr]]
end

Usage

• Generate AES_128 key:

{:ok, key} = AesCtr.generate_aes_key(:bytes)
{:ok, key_in_base64} = AesCtr.generate_aes_key(:base64)

• Generate AES_256 key:

{:ok, key} = AesCtr.generate_aes_key(:bytes, 256)
{:ok, key_in_base64} = AesCtr.generate_aes_key(:base64, 256)

• Encrypt text:

clear_text = "my-clear-text"
{:ok, aes_128_key} = AesCtr.generate_aes_key(:bytes)
{:ok, cipher} = AesCtr.encrypt(aes_128_key, clear_text)

• Decrypt cipher:

clear_text = "my-clear-text"
{:ok, aes_128_key} = AesCtr.generate_aes_key(:bytes)
{:ok, cipher} = AesCtr.encrypt(clear_text, aes_128_key)
{:ok, val} = AesCtr.decrypt(cipher, aes_128_key)
