This is a problem I am interested in a lot, and is perhaps the only reason I cannot completely move away from dedicated email clients on my computer. I am not well-versed in the issue, but I have read the infamous Masanto cryptography in JS article, rebuttals, differents JS projects revolving around cryptography. I currently am evaluating Firefox's WebPG for some functionality, but the dev has to work hard to basically build a Firefox plugin (in JS, so we are back to the same problem) to call GnuPG calls and return the data. So, we have browser specific plugins and web-app code in a language that is controversially unsuitable for such use in decryption cases. What can we use as alternative to secure web applications? Does asm.js change anything? As far as I can tell, no. Alternative browser languages? I guess, but still a pain. Are we going to have to build this functionality into web browsers, as a standard or otherwise. I am generally curious what people who are trying to engage this problem see in the future.
