Masking/Encryption

I’m very concerned that Woocommerce does not at least mask keys in the back end. Despite my best efforts (I pay decent money for protection through my host; I also have several layers of protection installed, and use best practices for logins, etc.), someone hacked my site. And in the other payment plugins I have on my site, it’s not possible to read the keys for the payment gateways, but on Woocommerce, nothing is even masked. Let’s at least make them work a little! If nothing else, for Braintree, add all the different keys, and mask or encrypt them. This should be basic functionality of every payment gateway, those in the core and for add-ons.
