Since in-browser encryption is a pretty new thing as far as file locker services go, we decided to start with a free usability beta so that we can gather direct feedback from our actual audience and get a better idea of how should we improve to make our users (which means you, I sincerely hope) happy.
As CIYAM Open is also doing in-browser encryption I would be interested to compare your .js to my own - have you got a link to the source I can examine?
Cheers,
Ian.
