Charles Engelke's Blog. March 1, 2015. Web Crypto on my AndroidWear Watch. 8212; Charles Engelke @ 4:28 pm. I just tried out some of the live web crypto demos that I’ve blogged about. On my Moto 360. Watch Most of them read files which doesn’t seem to work on a watch (go figure). But the one that creates and stores key pairs. It’s a pretty terrible user experience given that the page isn’t even well designed for a phone, much less a watch, but it works. Is a game changer. Blog at WordPress.com.

Charles Engelke's Blog. July 16, 2014. Symmetric Cryptography in the Browser Conclusion. 8212; Charles Engelke @ 8:36 pm. This series of posts. Is almost complete. We’ve created, imported, and exported AES keys and used them to encrypt and decrypt files, all inside a standard web browser using the new Web Cryptography API. All that’s left is to put it all together into a single web page. That’s what we’ll do now. The page and code discussed in here are available on Github. And as a live page. DOCTYPE htm...

Charles Engelke's Blog. February 14, 2015. Deriving Keys from Passwords with WebCrypto. 8212; Charles Engelke @ 1:02 pm. It has been quite a while since my last post.

The changes from the earlier draft are mostly fixed typos and improved consistency. The Web Cryptography API supports two KDFs: HKDF-CTR. This makes sure that the browser suppor...
