# JwtLite

Lightweight JWT decoder for Elixir. Decode and inspect JWTs without signature verification. Zero dependencies.

## Installation

```elixir
def deps do
  [{:jwt_lite, "~> 0.1"}]
end
```

## Usage

```elixir
token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0IiwibmFtZSI6IkFsaWNlIiwiZXhwIjo5OTk5OTk5OTk5fQ.sig"

{:ok, %{header: header, payload: payload}} = JwtLite.decode(token)
# => %{"alg" => "HS256", "typ" => "JWT"}

JwtLite.expired?(token)  # => false
JwtLite.ttl(token)       # => seconds until expiry
```

## API

- `JwtLite.decode/2` — decode to `{:ok, %{header, payload, signature}}`
- `JwtLite.decode!/2` — same but raises on error
- `JwtLite.expired?/1` — returns `true` if exp claim is in the past
- `JwtLite.ttl/1` — seconds remaining until expiry
