comment Is this design of client side encryption secure?
@AndreyBotalov: It's pretty tedious to "review" (or to ask "others" to review) a JavaScript application that could potentially be different every time it is downloaded from the server, potentially downloaded several times per user per day. Is there a good way to at least check if the version of the app I downloaded today is the same as the version I and others previously reviewed yesterday?

@RickyDemer: After some thought, I now think you are right --each package only needs to go through each participant once.

comment How to represent a 32-byte SHA2 hash in the shortest possible string?
@fgrieu: good point. Rather than the original base64, Geotarget probably wants RFC 4648 'base64url' "Base64 with URL and Filename Safe Alphabet". In order to guarantee that a program won't generate a base filename of "con" or some other reserved filename, and to make human-generated filenames such as "readme" usually sort before program-generated filenames, I typically make program-generated filenames start with lowercase 'z'.
