# js-sha512
This is a simple SHA-512, SHA-384, SHA-512/224, SHA-512/256 hash functions for JavaScript supports UTF-8 encoding.
## Install
For node.js, you can use this command to install:
npm install js-sha512
## Usage
If you use node.js, you should require the module first:
```JavaScript
sha512 = require('js-sha512');
```
or
```JavaScript
sha512 = require('js-sha512').sha512;
sha384 = require('js-sha512').sha384;
sha512_256 = require('js-sha512').sha512_256;
sha512_224 = require('js-sha512').sha512_224;
```
And you could use like this:
```JavaScript
sha512('Message to hash');
sha384('Message to hash');
sha512_256('Message to hash');
sha512_224('Message to hash');
```
## Example
Code
```JavaScript
sha512('');
sha512('The quick brown fox jumps over the lazy dog');
sha512('The quick brown fox jumps over the lazy dog.');
sha384('');
sha384('The quick brown fox jumps over the lazy dog');
sha384('The quick brown fox jumps over the lazy dog.');
sha512_256('');
sha512_256('The quick brown fox jumps over the lazy dog');
sha512_256('The quick brown fox jumps over the lazy dog.');
sha512_224('');
sha512_224('The quick brown fox jumps over the lazy dog');
sha512_224('The quick brown fox jumps over the lazy dog.');
```
Output

6d6a9279495ec4061769752e7ff9c68b6b0b3c5a281b7917ce0572de
It also supports UTF-8 encoding:
Code
```JavaScript
sha512('中文');
sha384('中文');
sha512_256('中文');
sha512_224('中文');
```
Output

## Tests
You can open `tests/index.html` in browser or use node.js to run test
node tests/node-test.js
or
npm test
## Extensions
### jQuery
If you prefer jQuery style, you can add following code to add a jQuery extension.
Code
```JavaScript
jQuery.sha512 = sha512
jQuery.sha384 = sha384
jQuery.sha512_256 = sha512_256
jQuery.sha512_224 = sha512_224
```
And then you could use like this:
```JavaScript
$.sha512('message');
$.sha384('message');
$.sha512_256('message');
$.sha512_224('message');
```
### Prototype
If you prefer prototype style, you can add following code to add a prototype extension.
Code
```JavaScript
String.prototype.sha512 = function() {
return sha512(this);
};
String.prototype.sha384 = function() {
return sha384(this);
};
String.prototype.sha512_256 = function() {
return sha512_256(this);
};
String.prototype.sha512_224 = function() {
return sha512_224(this);
};
```
And then you could use like this:
```JavaScript
'message'.sha512();
'message'.sha384();
'message'.sha512_256();
'message'.sha512_224();
```
