Another thing to point out, the Google developers respect the difficulty in securely implementing a Chrome extension that performs encryption. They are going through an extensive period of public review, and they're asking people to not build and deploy as a Chrome extension until after it's been thoroughly vetted. In contrast, the Mailvelope guys seem to have just flung something over the wall with little regard to the actual security of their implementation. Seems irresponsible at best.
