JWT is a simple authorization token format based on JSON. Peter Hizalev wrote this library at Kato.im. We're open-sourcing it in case someone else needs to create or parse JWT tokens with Erlang.
Install
git clone [email protected]:kato-im/ejwt.git && cd ejwt
./rebar get-deps
erl
In Erlang shell:
%% Create JWT token
application:start(crypto).
Key = <<"53F61451CAD6231FDCF6859C6D5B88C1EBD5DC38B9F7EBD990FADD4EB8EB9063">>.
Claims = {[
{user_id, <<"bob123">>},
{user_name, <<"Bob">>}
]}.
ExpirationSeconds = 86400,
Token = ejwt:jwt(<<"HS256">>, Claims, ExpirationSeconds, Key).
%% Parse JWT token
ejwt:parse_jwt(Token, Key).
You should get back the original claims Jterm, plus expiration claim:
{[
{<<"exp">>,1392607527},
{<<"user_id">>,<<"bob123">>},
{<<"user_name">>,<<"Bob">>}
]}
