## Installation
You can also install js-md2 by using Bower.
bower install js-md2
For node.js, you can use this command to install:
npm install js-md2
## Usage
If you use node.js, you should require the module first:
You could use like this:
```JavaScript
md2 = require('js-md2');
md2('Message to hash');
```
And you could use like this:
If you use node.js, you should require the module first:
```JavaScript
md2('Message to hash');
md2 = require('js-md2');
```
### Methods
#### md2(str, asciiOnly)
Hash string to md2, 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.
## Example
Code
```JavaScript
