Alex, Sean, you're the OpenPGP guru guys, what do you think on it? Frankly i don't have the deep knowledge to understand if the proposed fix solve the issue. I would just underline that this is a critical issue to be able to handle in "background" the encryption process without blocking the UI that will be able to show nice progress-bar on the status of operation. It would represent a major step in the "architectural constrain" of OpenPGPJS, let's improve it! -naif _______________________________________________ http://openpgpjs.org
