		# Captcha

		Simple captcha.
		Simple captcha for Connect/Express.

		## Installation

		## Usage (for Express 3)

		...
		var captcha = require('captcha');
		...
		app.configure(function(){
		...
		app.use(app.router);
		app.use(captcha('/captcha.jpg')); // url for captcha jpeg
		app.use(express.static(__dirname + '/public'));
		...
		```javascript
		var express = require('express');
		var captcha = require('captcha');

		## Color Options
		var app = express();

		You can setup colors with an object, instead of just URL, like this (CSS-notation of color):
		app.configure(function(){
		app.use(express.bodyParser());
		app.use(express.cookieParser());
		app.use(express.cookieSession({ secret: 'keyboard-cat' }));
		app.use(captcha({ url: '/captcha.jpg', color:'#0064cd', background: 'rgb(20,30,200)' })); // captcha params
		});

		...
		app.use(captcha({ url: '/captcha.jpg', color:'#0064cd', background: 'rgb(20,30,2}));
		...
		app.get('/', function(req, res){
		res.type('html');
		res.end('<img src="/captcha.jpg"/><form action="/login" method="post"><input type="text" name="digits"/></form>'); // captcha render
		});

		All color options are optional.
		app.post('/login', function(req, res){
		res.type('html');
		res.end('CONFIRM: ' + (req.body.digits == req.session.captcha)); // captcha verify
		});

		## Render captcha:

		<img src="/captcha.jpg" />

		## Check captcha:

		app.post('/user/create', function(req, res, next){
		if(req.body.captcha != req.session.captcha) // text from captcha stored into session
		return next(new Error('Captcha stop!'));
		...
