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:

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:

var md4 = require('js-md4');

It supports AMD:

require(['your/path/md4.js'], function (md4) {
// ...
});

See document

Example

md4(''); // 31d6cfe0d16ae931b73c59d7e0c089c0
md4('The quick brown fox jumps over the lazy dog'); // 1bee69a46ba811185c194762abaeae90
md4('The quick brown fox jumps over the lazy dog.'); // 2812c6c7136898c51f6f6739ad08750e

// It also supports UTF-8 encoding
md4('中文'); // 223088bf7bd45a16436b15360c5fc5a0

// It also supports byte `Array`, `Uint8Array`, `ArrayBuffer`
md4([]); // 31d6cfe0d16ae931b73c59d7e0c089c0
md4(new Uint8Array([])); // 31d6cfe0d16ae931b73c59d7e0c089c0

// Different output
md4(''); // 31d6cfe0d16ae931b73c59d7e0c089c0
md4.hex(''); // 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]
