## Installation
|
|
You can also install js-md4 by using Bower.
|
|
|
|
bower install js-md4
|
|
|
|
For node.js, you can use this command to install:
|
|
|
|
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');
|
|
```
|
|
It supports AMD:
|
|
```JavaScript
|
|
require(['your/path/md4.js'], function (md4) {
|
|
// ...
|
|
});
|
|
```
|
|

md4([]); // 31d6cfe0d16ae931b73c59d7e0c089c0
|
|
md4(new Uint8Array([])); // 31d6cfe0d16ae931b73c59d7e0c089c0
|
|
|
|
// Different output
|
|
md4(''); // 31d6cfe0d16ae931b73c59d7e0c089c0

md4.array(''); // [49, 214, 207, 224, 209, 106, 233, 49, 183, 60, 89, 215, 224, 192, 137, 192]
|
|
md4.digest(''); // [49, 214, 207, 224, 209, 106, 233, 49, 183, 60, 89, 215, 224, 192, 137, 192]
