Exgpg

Use gpg from elixir

Installation

Add this to your mixfile

 { :exgpg, "~> 0.0.1" },

Install goon and put it on your PATH. If you can run goon and get a usage output, then porcelain and thereby exgpg will be able to use it.

Usage

Symmetric

out = "test string"
|> Exgpg.symmetric([passphrase: "hunter2"])
|> Enum.into("")

out # this will be a binary of stuff

out = out
|> Exgpg.decrypt([passphrase: "hunter2"])
|> Enum.into("")

out # this will be "test string"

Asymmetric

keyrings = [
  secret_keyring: "/path/to/keyring.sec",
  keyring: "/path/to/keyring.pub"
]

out = "hello world"
|> Exgpg.encrypt([{:recipient, "test@test.com"} | keyrings])
|> Enum.into("")
|> Exgpg.decrypt(keyrings)
|> Enum.into("")

out # this will be "hello world"

Options are passed directly to gpg, with a transformation to change the the key_with_underscore keylist convention in elixir to the --key-with-dashes. Most options should Just Work™.
