# dibs_hmac

An implementation of DIBS Message authentication code. Has correct sorting and rules for which params to include. So far it only includes the params for DIBS Payment Window. This is production ready. I am curently using it for a Webshop.

## Code example

### Calculate mac

```ruby
dibs_params = {:amount => "100", :merchant => "2222", ....}

mac = DIBS::HMAC.calculate(dibs_params, Rails.application.config.dibs_hmac_key)
```
### Validate response from DIBS
```ruby
raise "INVALID REQUEST" unless DIBS::HMAC.valid?(params, Rails.application.config.dibs_hmac_key)
```
