-### Methods
-
-#### sha256(str, asciiOnly)
-
-Hash string to sha256, set asciiOnly to true for better performace if you ensure input is ascii.
-
-##### *str: `String`*
-
-String to hash.
-
-##### *asciiOnly: `Boolean` (default: `false`)*
-
-Specify the string encoding is ASCII.
-
-#### sha224(str, asciiOnly)
-
-Hash string to sha224, set asciiOnly to true for better performace if you ensure input is ascii.
-
-##### *str: `String`*

-## Extensions
-### jQuery
-If you prefer jQuery style, you can add following code to add a jQuery extension.
+It also supports byte `Array`, `Uint8Array`, `ArrayBuffer` input:

 Code
 ```JavaScript
-jQuery.sha256 = sha256
-jQuery.sha224 = sha224
+sha256([]);
+sha256(new Uint8Array([211, 212]));
 ```
-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.
