 Another possibility, is to use a hashing function, such as SHA256 to hash the password, but this method is vulnerable to [Rainbow Attacks](http://en.wikipedia.org/wiki/Rainbow_table), unless you use a [salt](http://en.wikipedia.org/wiki/Salt_(cryptography)).
 
+A simple way to do this in browser is using [js-sha256](https://github.com/emn178/js-sha256) like:
+
+```javascript
+var key_256 = sha256.array('salt' + 'password'.normalize('NFKC'));
