I have been playing around with the Web Cryptography API a lot lately. My most recent post was about getRandomValues(). I wanted to take a moment to investigate two more methods: generateKey() and exportKey(). The generation of a good cryptographic key is fairly fundamental. I wrote up a short demo app, to demonstrate how the two …

The W3C has been working on a Web Cryptography API for a while, now. The current version (11 December 2014) is their “Candidate Recommendation”. As such, I would not necessarily consider it fully ready for primetime but that does not mean that we can not play around with it a bit. I figured that today, we should …

There is a web API called FileReader() that nicely adds to that blurriness. It lets you asynchronously read the contents of a file on the user’s computer. I am going to show you one way of using it.

For this post, I created an example app that I am calling “Notes Vault.” My primary goal was to check out ngStorage but in doing so I also explored ng-options and ng-model. Let us take a look at the end result.
