# 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

    dibs_params = {:amount => "100", :merchant => "2222", ....}
    
    mac = DIBS::HMAC.calculate(dibs_params, Rails.application.config.dibs_hmac_key)

### Validate response from DIBS

    raise "INVALID REQUEST" unless DIBS::HMAC.valid?(params, Rails.application.config.dibs_hmac_key)
