## Usage

Uses Authorization HTTP Header, example:
```Authorization: ContentHash:Signature```

Signature is the "Public Key"

ContentHash is the HMAC encrypted Message

```ruby
map '/' do
  use Rack::SimpleAuth::HMAC, 'signature', 'private_key'
  run MyApplication
end
```

Private Key and Signature should be served by a file which is not checked into git version control.
