## Smoke test example
Compilation
```shell
make
make eunit
```
In Erlang shell:
```
%% Create JWT token
application:start(crypto).
Key = <<"53F61451CAD6231FDCF6859C6D5B88C1EBD5DC38B9F7EBD990FADD4EB8EB9063">>.
Claims = {[
{user_id, <<"bob123">>},
{user_name, <<"Bob">>}
]}.
ExpirationSeconds = 86400,
Token = erljwt:create(hs256, Claims, ExpirationSeconds, Key).
%% Parse JWT token
erljwt:parse(Token, Key).
```
You should get back the original claims ,plus expiration claim and the header and signature:
```
#{ claims =>
#{<<"exp">> => 1392607527,
<<"user_id">> => <<"bob123">>,
<<"user_name">> => <<"Bob">>
},
header => #{...},
signature => <<"lnmmaen....">>
}
```
