npm install js-md4
## Notice
`buffer` method is deprecated. This maybe confuse with Buffer in node.js. Please use `arrayBuffer` instead.
## Usage
You could use like this:
```JavaScript
md4('Message to hash');
var hash = md4.create();
hash.update('Message to hash');
hash.hex();
var hash2 = md4.update('Message to hash');
hash2.update('Message2 to hash');
hash2.array();
```
If you use node.js, you should require the module first:
```JavaScript
var md4 = require('js-md4');
md4 = require('js-md4');
```
It supports AMD:
```JavaScript
require(['your/path/md4.js'], function (md4) {
require(['your/path/md4.js'], function(md4) {
// ...
});
```
