-## Extensions
-### jQuery
-If you prefer jQuery style, you can add following code to add a jQuery extension.
-
-Code
-```JavaScript
-jQuery.sha256 = sha256
-jQuery.sha224 = sha224
-```
-And then you could use like this:
-```JavaScript
-$.sha256('message');
-$.sha224('message');
-```
-### Prototype
-If you prefer prototype style, you can add following code to add a prototype extension.
-
-Code
-```JavaScript
-String.prototype.sha256 = function() {
-  return sha256(this);
-};
-String.prototype.sha224 = function() {
-  return sha224(this);
-};
-```
-And then you could use like this:
-```JavaScript
-'message'.sha256();
-'message'.sha224();
-```
