How timely. This NSA fiasco has prompted me to finish up an old project https://boxuptext.com/, which is a convenient webapp to encrypt message to url entirely on the browser. It's ready for use.
Not many people use crypto because in general it's hard to set up and hard to use. A webapp is accessible and easy to use and provide reasonable security.
I know there's a prevailing view against doing crypto in Javascript, and I've gone the extra steps to address the negatives. At the end I think the benefits of doing javascript on the browser outweigh the negatives. See https://boxuptext.com/faq#benefits
