Is there any way to verify that the website is not stealing/storing priv keys?
Of course! You have 3 ways to do that:
- You can open the network tab of the dev tools and see that no external request is made after the pageload, which means nothing leaves your browser tab.
- You can also shut down your internet connection after the page is loaded, and everything will work fine as long as you don't refresh
- You can also download the latest build here : http://git.io/veth-dl and run it on a completely offline computer
This is fabulous, thank you so much! Great resource.
