A few months ago I did a weekend project (Private In Public) making a tool that let you encrypt very short bits of text in a single web page. You can read about it a bit more here.
It is now available as a (very early beta) Chrome Extension here. Anyone who is interested in hiding things §e:U2FsdGVkX1/XEh72t/QGzIROohr6hRnTVqwYyxhSbQ4=§ might find it cool, and I’d be really interested in your comments.
I’ve got some plans for things I want to use it for, but I like the idea that it might be useful more generally.
