JWT is a simple authorization token format based on JSON.

Installation

If you use rebar (supports both 2 and 3 versions) or mix (Elixir):

% in rebar.config for rebar3
{deps, [{jwt}]}.

% or for rebar2
{deps, [{jwt, ".*", {git, "https://github.com/artemeff/jwt", {tag, "0.1.0"}}}]}

% mix.exs
def deps do
  [{:jwt, "~> 0.1"}]
end

Or use it as git dependency.

Usage example

%% Create JWT token
> application:ensure_all_started(jwt).
> Key = <<"supas3cri7">>.
> Claims = [
    {user_id, 42},
    {user_name, <<"Bob">>}
  ].
> {ok, Token} = jwt:encode(<<"HS256">>, Claims, Key).
%% or with expiration
> ExpirationSeconds = 86400.
> {ok, Token} = jwt:encode(<<"HS256">>, Claims, ExpirationSeconds, Key).

%% Parse JWT token
> {ok, Claims} = jwt:decode(Token, Key).
