I\'m looking to do some client-side PGP encryption in Javascript. I\'ve found some GPL library scattered on the web, but for obvious reason, I cannot use that code due to licens
I recently found a MIT licensed client-side javascript library:
https://github.com/bitwiseshiftleft/sjcl
It works well so far, and it allows for a full-client side encryption of the data. Ensuring that even before the data leaves the browser, it is already safe using a public-private key encryption scheme.
OpenPGP.js is probably the most complete and fastest implementation (it's a collaborative effort) and licensed under the LGPL. You might want to join their mailing list.
See http://www.hanewin.net/encrypt/
I know this is an old question, but I recently found: https://keybase.io/kbpgp when looking for a similar item. BSD Licensed instead of *GPL.
