ExfileEncryption

Build Status

Encryption for Exfile files.

Installation

  1. Add exfile_encryption to your list of dependencies in mix.exs:
def deps do
  [{:exfile_encryption, "~> 0.0.1"}]
end
  1. Ensure exfile_encryption is started before your application:
def application do
  [applications: [:exfile_encryption]]
end

Usage

exfile_encryption registers two processors. Each recieves a single argument, key, with the encryption key.

  • encrypt
  • decrypt

Configuration

exfile_encryption is designed to be used with Exfile’s pre- and post-processing support.

Sample configuration of a backend that uses exfile_encryption to encrypt files stored on the “store” store

config :exfile, Exfile,
  backends: %{
    "store" => [Exfile.Backend.FileSystem, %{
      directory: "/var/lib/my-store",
      max_size: nil,
      hasher: Exfile.Hasher.Random,
      preprocessors: [{"encrypt", [key: "don't tell anyone!"]}],
      postprocessors: [{"decrypt", [key: "don't tell anyone!"]}]
    }]
  }
