+When I used Chrome canary, it said that importKey method is not recognized. So when I 'console'ed it with Chrome, the control did not go beyond the importKey method. What could possibly be the problem?
+Chrome restricts the usage of WebCryptographyApi to secure origins. It means 'https'. localhost is a special address enabled for development. Therefore, to use WebCrypto in a real environment you need to setup a SSL/TLS server
