How I can output Craft Commerces Stripes Publishable Key in a template I would like to know how I can output Craft Commerces Stripes Publishable Key, which I define under Payment Methods, in a template? 

The value I set is settings[publishableKey].

Thanks
Stefan
Like this:

{% if cart.paymentMethod.class == 'Stripe' %}
    {{ cart.paymentMethod.settings.publishableKey }}
{% endif %}
