# js-sha1
This is a simple SHA1 hash function for JavaScript supports UTF-8 encoding.
## Install
For node.js, you can use this command to install:
npm install js-sha1
## Usage
If you use node.js, you should require the module first:
var sha1 = require('js-sha1');
And you could use like this:
sha1('Message to hash');
## Example

## Run Tests
## Tests
You can open `tests/index.html` in browser or use node.js to run `node tests/node-test.js` for test.
You also could use `npm test` instance of `node tests/node-test.js`.
## Extensions
### jQuery
If you prefer jQuery style, you can add following code to add a jQuery extension.
