+# connect-flash
+
+The flash is a special area of the session used for storing messages.  Messages
+are written to the flash and cleared after being displayed to the user.  The
+flash is typically used in combination with redirects, ensuring that the message
+is available to the next page that is to be rendered.
+
+This middleware was extracted from [Express](http://expressjs.com/) 2.x, after
+Express 3.x removed direct support for the flash.  connect-flash brings this
+functionality back to Express 3.x, as well as any other middleware-compatible
+framework or application. +1 for [radical reusability](http://substack.net/posts/b96642/the-node-js-aesthetic).
+
+## Install
+
+    $ npm install connect-flash
+
+## Usage
+
+#### Express 3.x
+
+Flash messages are stored in the session.  First, setup sessions as usual by
+enabling `cookieParser` and `session` middleware.  Then, use `flash` middleware
+provided by connect-flash.
+
+```javascript
+var flash = require('connect-flash');
+var app = express();
+
+app.configure(function() {
+  app.use(express.cookieParser('keyboard cat'));
+  app.use(express.session({ cookie: { maxAge: 60000 }}));
+  app.use(flash());
+});
+```
+
+With the `flash` middleware in place, all requests will have a `req.flash()` function
+that can be used for flash messages.
+
+```javascript
+app.get('/flash', function(req, res){
+  // Set a flash message by passing the key, followed by the value, to req.flash().
+  req.flash('info', 'Flash is back!')
+  res.redirect('/');
+});
+
+app.get('/', function(req, res){
+  // Get an array of flash messages by passing the key to req.flash()
+  res.render('index', { messages: req.flash('info') });
+});
+```
+
+## Examples
+
+For an example using connect-flash in an Express 3.x app, refer to the [express3](https://github.com/jaredhanson/connect-flash/tree/master/examples/express3)
+example.
+
+## Tests
+
+    $ npm install --dev
+    $ make test

+
+Module for calculating Cyclic Redundancy Check (CRC) for Node.js and the Browser.
+
+## Features
+
+* Full test suite comparing values against reference `pycrc` implementation.
+* Version 3.x is 3x to 4x faster than version 2.x.
+* Pure JavaScript implementation, no dependencies.
+* Provides CRC Tables for optimized calculations.
+* Provides support for the following CRC algorithms:
+  * CRC1 `crc.crc1(…)`
+  * CRC8 `crc.crc8(…)`
+  * CRC8 1-Wire `crc.crc81wire(…)`
+  * CRC16 `crc.crc16(…)`
+  * CRC16 CCITT `crc.crc16ccitt(…)`
+  * CRC16 Modbus `crc.crc16modbus(…)`
+  * CRC16 Kermit `crc.crc16kermit(…)`
+  * CRC16 XModem `crc.crc16xmodem(…)`
+  * CRC24 `crc.crc24(…)`
+  * CRC32 `crc.crc32(…)`
+
+## IMPORTANT
+
+If you've used `crc` module prior to version 2.x, you might have some inconsistencies with the current implementation because it relied on very old code and wasn't checked against reference implementation. If you upgrading from 1.x, please take special care.
+
+## Support

+## Installation
+
+    npm install crc
+
+## Running tests
+
+    $ npm install
+    $ npm test
+
+## Usage Example
+
+Calculate a CRC32:
+
+    var crc = require('crc');
+
+    crc.crc32('hello').toString(16);
+    # => "3610a686"
+
+Calculate a CRC32 of a file:
+
+    crc.crc32(fs.readFileSync('README.md', 'utf8')).toString(16);
+    # => "127ad531"
+
+Or using a `Buffer`:
+
+    crc.crc32(fs.readFileSync('README.md')).toString(16);
+    # => "127ad531"
+
+Incrementally calculate a CRC32:
+
+    value = crc.crc32('one');
+    value = crc.crc32('two', value);
+    value = crc.crc32('three', value);
+    value.toString(16);
+    # => "9e1c092"
+

+
+Logic behind CSRF token creation and verification.
+
+Read [Understanding-CSRF](https://github.com/pillarjs/understanding-csrf)
+for more information on CSRF. Use this module to create custom CSRF middleware.
+
+Looking for a CSRF framework for your favorite framework that uses this
+module?
+
+  * Express/connect: [csurf](https://www.npmjs.com/package/csurf) or
+    [alt-xsrf](https://www.npmjs.com/package/alt-xsrf)
+  * Koa: [koa-csrf](https://www.npmjs.com/package/koa-csrf) or
+    [koa-atomic-session](https://www.npmjs.com/package/koa-atomic-session)
+
+### Install
+
+```bash
+$ npm install csrf
+```
+
+## API
+
+```js
+var Tokens = require('csrf')
+```
+
+### new Tokens([options])
+
+Create a new token generation/verification instance. The `options` argument is
+optional and will just use all defaults if missing.
+
+#### Options
+
+Tokens accepts these properties in the options object.
+
+##### saltLength
+
+The length of the internal salt to use, in characters. Internally, the salt
+is a base 62 string. Defaults to `8` characters.
+
+##### secretLength
+
+The length of the secret to generate, in bytes. Note that the secret is
+passed around base-64 encoded and that this length refers to the underlying
+bytes, not the length of the base-64 string. Defaults to `18` bytes.
+
+#### tokens.create(secret)
+
+Create a new CSRF token attached to the given `secret`. The `secret` is a
+string, typically generated from the `tokens.secret()` or `tokens.secretSync()`
+methods. This token is what you should add into HTML `<form>` blocks and
+expect the user's browser to provide back.
+
+```js
+var secret = tokens.secretSync()
+var token = tokens.create(secret)
+```
+
+#### tokens.secret(callback)
+
+Asynchronously create a new `secret`, which is a string. The secret is to
+be kept on the server, typically stored in a server-side session for the
+user. The secret should be at least per user.
+
+```js
+tokens.secret(function (err, secret) {
+  if (err) throw err
+  // do something with the secret
+})
+```
+
+#### tokens.secret()
+
+Asynchronously create a new `secret` and return a `Promise`. Please see
+`tokens.secret(callback)` documentation for full details.
+
+**Note**: To use promises in Node.js _prior to 0.12_, promises must be
+"polyfilled" using `global.Promise = require('bluebird')`.
+
+```js
+tokens.secret().then(function (secret) {
+  // do something with the secret
+})
+```
+
+#### tokens.secretSync()
+
+A synchronous version of `tokens.secret(callback)`. Please see
+`tokens.secret(callback)` documentation for full details.
+
+```js
+var secret = tokens.secretSync()
+```
+
+#### tokens.verify(secret, token)
+
+Check whether a CSRF token is valid for the given `secret`, returning
+a Boolean.
+
+```js
+if (!tokens.verify(secret, token)) {
+  throw new Error('invalid token!')
+}
+```

+
+Node.js [CSRF](https://en.wikipedia.org/wiki/Cross-site_request_forgery) protection middleware.
+
+Requires either a session middleware or [cookie-parser](https://www.npmjs.com/package/cookie-parser) to be initialized first.
+
+  * If you are setting the ["cookie" option](#cookie) to a non-`false` value,
+    then you must use [cookie-parser](https://www.npmjs.com/package/cookie-parser)
+    before this module.
+  * Otherwise, you must use a session middleware before this module. For example:
+    - [express-session](https://www.npmjs.com/package/express-session)
+    - [cookie-session](https://www.npmjs.com/package/cookie-session)
+
+If you have questions on how this module is implemented, please read
+[Understanding CSRF](https://github.com/pillarjs/understanding-csrf).
+
+## Installation
+
+```sh
+$ npm install csurf
+```
+
+## API
+
+```js
+var csurf = require('csurf')
+```
+
+### csurf([options])
+
+Create a middleware for CSRF token creation and validation. This middleware
+adds a `req.csrfToken()` function to make a token which should be added to
+requests which mutate state, within a hidden form field, query-string etc.
+This token is validated against the visitor's session or csrf cookie.
+
+#### Options
+
+The `csurf` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### cookie
+
+Determines if the token secret for the user should be stored in a cookie
+or in `req.session`. Defaults to `false`.
+
+When set to `true` (or an object of options for the cookie), then the module
+changes behavior and no longer uses `req.session`. This means you _are no
+longer required to use a session middleware_. Instead, you do need to use the
+[cookie-parser](https://www.npmjs.com/package/cookie-parser) middleware in
+your app before this middleware.
+
+When set to an object, cookie storage of the secret is enabled and the
+object contains options for this functionality (when set to `true`, the
+defaults for the options are used). The options may contain any of the
+following keys:
+
+  - `key` - the name of the cookie to use to store the token secret
+    (defaults to `'_csrf'`).
+  - `path` - the path of the cookie (defaults to `'/'`).
+  - any other [res.cookie](http://expressjs.com/4x/api.html#res.cookie)
+    option can be set.
+
+##### ignoreMethods
+
+An array of the methods for which CSRF token checking will disabled.
+Defaults to `['GET', 'HEAD', 'OPTIONS']`.
+
+##### sessionKey
+
+Determines what property ("key") on `req` the session object is located.
+Defaults to `'session'` (i.e. looks at `req.session`). The CSRF secret
+from this library is stored and read as `req[sessionKey].csrfSecret`.
+
+If the ["cookie" option](#cookie) is not `false`, then this option does
+nothing.
+
+##### value
+
+Provide a function that the middleware will invoke to read the token from
+the request for validation. The function is called as `value(req)` and is
+expected to return the token as a string.
+
+The default value is a function that reads the token from the following
+locations, in order:
+
+  - `req.body._csrf` - typically generated by the `body-parser` module.
+  - `req.query._csrf` - a built-in from Express.js to read from the URL
+    query string.
+  - `req.headers['csrf-token']` - the `CSRF-Token` HTTP request header.
+  - `req.headers['xsrf-token']` - the `XSRF-Token` HTTP request header.
+  - `req.headers['x-csrf-token']` - the `X-CSRF-Token` HTTP request header.
+  - `req.headers['x-xsrf-token']` - the `X-XSRF-Token` HTTP request header.
+
+## Example
+
+### Simple express example
+
+The following is an example of some server-side code that generates a form
+that requires a CSRF token to post back.
+
+```js
+var cookieParser = require('cookie-parser')
+var csrf = require('csurf')
+var bodyParser = require('body-parser')
+var express = require('express')
+
+// setup route middlewares
+var csrfProtection = csrf({ cookie: true })
+var parseForm = bodyParser.urlencoded({ extended: false })
+
+// create express app
+var app = express()
+
+// parse cookies
+// we need this because "cookie" is true in csrfProtection
+app.use(cookieParser())
+
+app.get('/form', csrfProtection, function(req, res) {
+  // pass the csrfToken to the view
+  res.render('send', { csrfToken: req.csrfToken() })
+})
+
+app.post('/process', parseForm, csrfProtection, function(req, res) {
+  res.send('data is being processed')
+})
+```
+
+Inside the view (depending on your template language; handlebars-style
+is demonstrated here), set the `csrfToken` value as the value of a hidden
+input field named `_csrf`:
+
+```html
+<form action="/process" method="POST">
+  <input type="hidden" name="_csrf" value="{{csrfToken}}">
+  
+  Favorite color: <input type="text" name="favoriteColor">
+  <button type="submit">Submit</button>
+</form>
+```
+
+### Ignoring Routes
+
+**Note** CSRF checks should only be disabled for requests that you expect to
+come from outside of your website. Do not disable CSRF checks for requests
+that you expect to only come from your website. An existing session, even if
+it belongs to an authenticated user, is not enough to protect against CSRF
+attacks.
+
+The following is an example of how to order your routes so that certain endpoints
+do not check for a valid CSRF token.
+
+```js
+var cookieParser = require('cookie-parser')
+var csrf = require('csurf')
+var bodyParser = require('body-parser')
+var express = require('express')
+
+// create express app
+var app = express()
+
+// create api router
+var api = createApiRouter()
+
+// mount api before csrf is appended to the app stack
+app.use('/api', api)
+
+// now add csrf and other middlewares, after the "/api" was mounted
+app.use(bodyParser.urlencoded({ extended: false }))
+app.use(cookieParser())
+app.use(csrf({ cookie: true }))
+
+app.get('/form', function(req, res) {
+  // pass the csrfToken to the view
+  res.render('send', { csrfToken: req.csrfToken() })
+})
+
+app.post('/process', function(req, res) {
+  res.send('csrf was required to get here')
+})
+
+function createApiRouter() {
+  var router = new express.Router()
+
+  router.post('/getProfile', function(req, res) {
+    res.send('no csrf to get here')
+  })
+
+  return router
+}
+```
+
+### Custom error handling
+
+When the CSRF token validation fails, an error is thrown that has
+`err.code === 'EBADCSRFTOKEN'`. This can be used to display custom
+error messages.
+
+```js
+var bodyParser = require('body-parser')
+var cookieParser = require('cookie-parser')
+var csrf = require('csurf')
+var express = require('express')
+
+var app = express()
+app.use(bodyParser.urlencoded({ extended: false }))
+app.use(cookieParser())
+app.use(csrf({ cookie: true }))
+
+// error handler
+app.use(function (err, req, res, next) {
+  if (err.code !== 'EBADCSRFTOKEN') return next(err)
+
+  // handle CSRF token errors here
+  res.status(403)
+  res.send('form tampered with')
+})
+```

+## Installation
+
+```bash
+$ npm install express-session
+```
+
+## API
+
+```js
+var session = require('express-session')
+```
+
+### session(options)
+
+Create a session middleware with the given `options`.
+
+**Note** Session data is _not_ saved in the cookie itself, just the session ID.
+Session data is stored server-side.
+
+**Note** Since version 1.5.0, the [`cookie-parser` middleware](https://www.npmjs.com/package/cookie-parser)
+no longer needs to be used for this module to work. This module now directly reads
+and writes cookies on `req`/`res`. Using `cookie-parser` may result in issues
+if the `secret` is not the same between this module and `cookie-parser`.
+
+**Warning** The default server-side session storage, `MemoryStore`, is _purposely_
+not designed for a production environment. It will leak memory under most
+conditions, does not scale past a single process, and is meant for debugging and
+developing.
+
+For a list of stores, see [compatible session stores](#compatible-session-stores).
+
+#### Options
+
+`express-session` accepts these properties in the options object.
+
+##### cookie
+
+Settings object for the session ID cookie. The default value is
+`{ path: '/', httpOnly: true, secure: false, maxAge: null }`.
+
+The following are options that can be set in this object.
+
+###### domain
+
+Specifies the value for the `Domain` `Set-Cookie` attribute. By default, no domain
+is set, and most clients will consider the cookie to apply to only the current
+domain.
+
+###### expires
+
+Specifies the `Date` object to be the value for the `Expires` `Set-Cookie` attribute.
+By default, no expiration is set, and most clients will consider this a
+"non-persistent cookie" and will delete it on a condition like exiting a web browser
+application.
+
+**Note** If both `expires` and `maxAge` are set in the options, then the last one
+defined in the object is what is used.
+
+**Note** The `expires` option should not be set directly; instead only use the `maxAge`
+option.
+
+###### httpOnly
+
+Specifies the `boolean` value for the `HttpOnly` `Set-Cookie` attribute. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly`
+attribute is set.
+
+**Note** be careful when setting this to `true`, as compliant clients will not allow
+client-side JavaScript to see the cookie in `document.cookie`.
+
+###### maxAge
+
+Specifies the `number` (in milliseconds) to use when calculating the `Expires`
+`Set-Cookie` attribute. This is done by taking the current server time and adding
+`maxAge` milliseconds to the value to calculate an `Expires` datetime. By default,
+no maximum age is set.
+
+**Note** If both `expires` and `maxAge` are set in the options, then the last one
+defined in the object is what is used.
+
+###### path
+
+Specifies the value for the `Path` `Set-Cookie`. By default, this is set to `'/'`, which
+is the root path of the domain.
+
+###### sameSite
+
+Specifies the `boolean` or `string` to be the value for the `SameSite` `Set-Cookie` attribute.
+
+  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+  - `false` will not set the `SameSite` attribute.
+  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in the specification
+https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1
+
+**Note** This is an attribute that has not yet been fully standardized, and may change in
+the future. This also means many clients may ignore this attribute until they understand it.
+
+###### secure
+
+Specifies the `boolean` value for the `Secure` `Set-Cookie` attribute. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure`
+attribute is not set.
+
+**Note** be careful when setting this to `true`, as compliant clients will not send
+the cookie back to the server in the future if the browser does not have an HTTPS
+connection.
+
+Please note that `secure: true` is a **recommended** option. However, it requires
+an https-enabled website, i.e., HTTPS is necessary for secure cookies. If `secure`
+is set, and you access your site over HTTP, the cookie will not be set. If you
+have your node.js behind a proxy and are using `secure: true`, you need to set
+"trust proxy" in express:
+
+```js
+var app = express()
+app.set('trust proxy', 1) // trust first proxy
+app.use(session({
+  secret: 'keyboard cat',
+  resave: false,
+  saveUninitialized: true,
+  cookie: { secure: true }
+}))
+```
+
+For using secure cookies in production, but allowing for testing in development,
+the following is an example of enabling this setup based on `NODE_ENV` in express:
+
+```js
+var app = express()
+var sess = {
+  secret: 'keyboard cat',
+  cookie: {}
+}
+
+if (app.get('env') === 'production') {
+  app.set('trust proxy', 1) // trust first proxy
+  sess.cookie.secure = true // serve secure cookies
+}
+
+app.use(session(sess))
+```
+
+The `cookie.secure` option can also be set to the special value `'auto'` to have
+this setting automatically match the determined security of the connection. Be
+careful when using this setting if the site is available both as HTTP and HTTPS,
+as once the cookie is set on HTTPS, it will no longer be visible over HTTP. This
+is useful when the Express `"trust proxy"` setting is properly setup to simplify
+development vs production configuration.
+
+##### genid
+
+Function to call to generate a new session ID. Provide a function that returns
+a string that will be used as a session ID. The function is given `req` as the
+first argument if you want to use some value attached to `req` when generating
+the ID.
+
+The default value is a function which uses the `uid-safe` library to generate IDs.
+
+**NOTE** be careful to generate unique IDs so your sessions do not conflict.
+
+```js
+app.use(session({
+  genid: function(req) {
+    return genuuid() // use UUIDs for session IDs
+  },
+  secret: 'keyboard cat'
+}))
+```
+
+##### name
+
+The name of the session ID cookie to set in the response (and read from in the
+request).
+
+The default value is `'connect.sid'`.
+
+**Note** if you have multiple apps running on the same hostname (this is just
+the name, i.e. `localhost` or `127.0.0.1`; different schemes and ports do not
+name a different hostname), then you need to separate the session cookies from
+each other. The simplest method is to simply set different `name`s per app.
+
+##### proxy
+
+Trust the reverse proxy when setting secure cookies (via the "X-Forwarded-Proto"
+header).
+
+The default value is `undefined`.
+
+  - `true` The "X-Forwarded-Proto" header will be used.
+  - `false` All headers are ignored and the connection is considered secure only
+    if there is a direct TLS/SSL connection.
+  - `undefined` Uses the "trust proxy" setting from express
+
+##### resave
+
+Forces the session to be saved back to the session store, even if the session
+was never modified during the request. Depending on your store this may be
+necessary, but it can also create race conditions where a client makes two
+parallel requests to your server and changes made to the session in one
+request may get overwritten when the other request ends, even if it made no
+changes (this behavior also depends on what store you're using).
+
+The default value is `true`, but using the default has been deprecated,
+as the default will change in the future. Please research into this setting
+and choose what is appropriate to your use-case. Typically, you'll want
+`false`.
+
+How do I know if this is necessary for my store? The best way to know is to
+check with your store if it implements the `touch` method. If it does, then
+you can safely set `resave: false`. If it does not implement the `touch`
+method and your store sets an expiration date on stored sessions, then you
+likely need `resave: true`.
+
+##### rolling
+
+Force a session identifier cookie to be set on every response. The expiration
+is reset to the original [`maxAge`](#cookiemaxage), resetting the expiration
+countdown.
+
+The default value is `false`.
+
+**Note** When this option is set to `true` but the `saveUninitialized` option is
+set to `false`, the cookie will not be set on a response with an uninitialized
+session.
+
+##### saveUninitialized
+
+Forces a session that is "uninitialized" to be saved to the store. A session is
+uninitialized when it is new but not modified. Choosing `false` is useful for
+implementing login sessions, reducing server storage usage, or complying with
+laws that require permission before setting a cookie. Choosing `false` will also
+help with race conditions where a client makes multiple parallel requests
+without a session.
+
+The default value is `true`, but using the default has been deprecated, as the
+default will change in the future. Please research into this setting and
+choose what is appropriate to your use-case.
+
+**Note** if you are using Session in conjunction with PassportJS, Passport
+will add an empty Passport object to the session for use after a user is
+authenticated, which will be treated as a modification to the session, causing
+it to be saved. *This has been fixed in PassportJS 0.3.0*
+
+##### secret
+
+**Required option**
+
+This is the secret used to sign the session ID cookie. This can be either a string
+for a single secret, or an array of multiple secrets. If an array of secrets is
+provided, only the first element will be used to sign the session ID cookie, while
+all the elements will be considered when verifying the signature in requests.
+
+##### store
+
+The session store instance, defaults to a new `MemoryStore` instance.
+
+##### unset
+
+Control the result of unsetting `req.session` (through `delete`, setting to `null`,
+etc.).
+
+The default value is `'keep'`.
+
+  - `'destroy'` The session will be destroyed (deleted) when the response ends.
+  - `'keep'` The session in the store will be kept, but modifications made during
+    the request are ignored and not saved.
+
+### req.session
+
+To store or access session data, simply use the request property `req.session`,
+which is (generally) serialized as JSON by the store, so nested objects
+are typically fine. For example below is a user-specific view counter:
+
+```js
+// Use the session middleware
+app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}))
+
+// Access the session as req.session
+app.get('/', function(req, res, next) {
+  var sess = req.session
+  if (sess.views) {
+    sess.views++
+    res.setHeader('Content-Type', 'text/html')
+    res.write('<p>views: ' + sess.views + '</p>')
+    res.write('<p>expires in: ' + (sess.cookie.maxAge / 1000) + 's</p>')
+    res.end()
+  } else {
+    sess.views = 1
+    res.end('welcome to the session demo. refresh!')
+  }
+})
+```
+
+#### Session.regenerate()
+
+To regenerate the session simply invoke the method. Once complete,
+a new SID and `Session` instance will be initialized at `req.session`.
+
+```js
+req.session.regenerate(function(err) {
+  // will have a new session here
+})
+```
+
+#### Session.destroy()
+
+Destroys the session, removing `req.session`; will be re-generated next request.
+
+```js
+req.session.destroy(function(err) {
+  // cannot access session here
+})
+```
+
+#### Session.reload()
+
+Reloads the session data.
+
+```js
+req.session.reload(function(err) {
+  // session updated
+})
+```
+
+#### Session.save()
+
+Save the session back to the store, replacing the contents on the store with the
+contents in memory (though a store may do something else--consult the store's
+documentation for exact behavior).
+
+This method is automatically called at the end of the HTTP response if the
+session data has been altered (though this behavior can be altered with various
+options in the middleware constructor). Because of this, typically this method
+does not need to be called.
+
+There are some cases where it is useful to call this method, for example, long-
+lived requests or in WebSockets.
+
+```js
+req.session.save(function(err) {
+  // session saved
+})
+```
+
+#### Session.touch()
+
+Updates the `.maxAge` property. Typically this is
+not necessary to call, as the session middleware does this for you.
+
+### req.session.id
+
+Each session has a unique ID associated with it. This property will
+contain the session ID and cannot be modified.
+
+### req.session.cookie
+
+Each session has a unique cookie object accompany it. This allows
+you to alter the session cookie per visitor. For example we can
+set `req.session.cookie.expires` to `false` to enable the cookie
+to remain for only the duration of the user-agent.
+
+#### Cookie.maxAge
+
+Alternatively `req.session.cookie.maxAge` will return the time
+remaining in milliseconds, which we may also re-assign a new value
+to adjust the `.expires` property appropriately. The following
+are essentially equivalent
+
+```js
+var hour = 3600000
+req.session.cookie.expires = new Date(Date.now() + hour)
+req.session.cookie.maxAge = hour
+```
+
+For example when `maxAge` is set to `60000` (one minute), and 30 seconds
+has elapsed it will return `30000` until the current request has completed,
+at which time `req.session.touch()` is called to reset `req.session.maxAge`
+to its original value.
+
+```js
+req.session.cookie.maxAge // => 30000
+```
+
+### req.sessionID
+
+To get the ID of the loaded session, access the request property
+`req.sessionID`. This is simply a read-only value set when a session
+is loaded/created.
+
+## Session Store Implementation
+
+Every session store _must_ be an `EventEmitter` and implement specific
+methods. The following methods are the list of **required**, **recommended**,
+and **optional**.
+
+  * Required methods are ones that this module will always call on the store.
+  * Recommended methods are ones that this module will call on the store if
+    available.
+  * Optional methods are ones this module does not call at all, but helps
+    present uniform stores to users.
+
+For an example implementation view the [connect-redis](http://github.com/visionmedia/connect-redis) repo.
+
+### store.all(callback)
+
+**Optional**
+
+This optional method is used to get all sessions in the store as an array. The
+`callback` should be called as `callback(error, sessions)`.
+
+### store.destroy(sid, callback)
+
+**Required**
+
+This required method is used to destroy/delete a session from the store given
+a session ID (`sid`). The `callback` should be called as `callback(error)` once
+the session is destroyed.
+
+### store.clear(callback)
+
+**Optional**
+
+This optional method is used to delete all sessions from the store. The
+`callback` should be called as `callback(error)` once the store is cleared.
+
+### store.length(callback)
+
+**Optional**
+
+This optional method is used to get the count of all sessions in the store.
+The `callback` should be called as `callback(error, len)`.
+
+### store.get(sid, callback)
+
+**Required**
+
+This required method is used to get a session from the store given a session
+ID (`sid`). The `callback` should be called as `callback(error, session)`.
+
+The `session` argument should be a session if found, otherwise `null` or
+`undefined` if the session was not found (and there was no error). A special
+case is made when `error.code === 'ENOENT'` to act like `callback(null, null)`.
+
+### store.set(sid, session, callback)
+
+**Required**
+
+This required method is used to upsert a session into the store given a
+session ID (`sid`) and session (`session`) object. The callback should be
+called as `callback(error)` once the session has been set in the store.
+
+### store.touch(sid, session, callback)
+
+**Recommended**
+
+This recommended method is used to "touch" a given session given a
+session ID (`sid`) and session (`session`) object. The `callback` should be
+called as `callback(error)` once the session has been touched.
+
+This is primarily used when the store will automatically delete idle sessions
+and this method is used to signal to the store the given session is active,
+potentially resetting the idle timer.

+
+Execute a listener when a response is about to write headers.
+
+## Installation
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+```js
+var onHeaders = require('on-headers')
+```
+
+### onHeaders(res, listener)
+
+This will add the listener `listener` to fire when headers are emitted for `res`.
+The listener is passed the `response` object as it's context (`this`). Headers are
+considered to be emitted only once, right before they are sent to the client.
+
+When this is called multiple times on the same `res`, the `listener`s are fired
+in the reverse order they were added.
+
+## Examples
+
+```js
+var http = require('http')
+var onHeaders = require('on-headers')
+
+http
+.createServer(onRequest)
+.listen(3000)
+
+function addPoweredBy() {
+  // set if not set by end of request
+  if (!this.getHeader('X-Powered-By')) {
+    this.setHeader('X-Powered-By', 'Node.js')
+  }
+}
+
+function onRequest(req, res) {
+  onHeaders(res, addPoweredBy)
+
+  res.setHeader('Content-Type', 'text/plain')
+  res.end('hello!')
+}
+```
+
+## Testing
+
+```sh
+$ npm test

+
+
+An abstract class implementing [Passport](http://passportjs.org/)'s strategy
+API.
+
+## Install
+
+    $ npm install passport-strategy
+
+## Usage
+
+This module exports an abstract `Strategy` class that is intended to be
+subclassed when implementing concrete authentication strategies.  Once
+implemented, such strategies can be used by applications that utilize Passport
+middleware for authentication.
+
+#### Subclass Strategy
+
+Create a new `CustomStrategy` constructor which inherits from `Strategy`:
+
+```javascript
+var util = require('util')
+  , Strategy = require('passport-strategy');
+
+function CustomStrategy(...) {
+  Strategy.call(this);
+}
+
+util.inherits(CustomStrategy, Strategy);
+```
+
+#### Implement Authentication
+
+Implement `autheticate()`, performing the necessary operations required by the
+authentication scheme or protocol being implemented.
+
+```javascript
+CustomStrategy.prototype.authenticate = function(req, options) {
+  // TODO: authenticate request
+}
+```
+
+## Tests
+
+    $ npm install
+    $ npm test

Once\nimplemented, such strategies can be used by applications that utilize Passport\nmiddleware for authentication.\n\n#### Subclass Strategy\n\nCreate a new `CustomStrategy` constructor which inherits from `Strategy`:\n\n```javascript\nvar util = require('util')\n  , Strategy = require('passport-strategy');\n\nfunction CustomStrategy(...) {\n  Strategy.call(this);\n}\n\nutil.inherits(CustomStrategy, Strategy);\n```\n\n#### Implement Authentication\n\nImplement `autheticate()`, performing the necessary operations required by the\nauthentication scheme or protocol being implemented.\n\n```javascript\nCustomStrategy.prototype.authenticate = function(req, options) {\n  // TODO: authenticate request\n}\n```\n\n## Tests\n\n    $ npm install\n    $ npm test\n\n## Credits\n\n  - [Jared Hanson](http://github.com/jaredhanson)\n\n## License\n\n[The MIT License](http://opensource.org/licenses/MIT)\n\nCopyright (c) 2011-2013 Jared Hanson <[http://jaredhanson.net/](http://jaredhanson.net/)>\n",

+ *
+ * Note that sessions are not strictly required for Passport to operate.
+ * However, as a general rule, most web applications will make use of sessions.
+ * An exception to this rule would be an API server, which expects each HTTP
+ * request to provide credentials in an Authorization header.

+ * Examples:
+ *
+ *     app.use(connect.cookieParser());
+ *     app.use(connect.session({ secret: 'keyboard cat' }));

+ *                        object from the session.  Defaults to _false_.  Should
+ *                        be set to true in cases where middleware consuming the
+ *                        request body is configured after passport and the

+ * Registers a function used to transform auth info.

+ * For example, when using bearer tokens for API authentication, the tokens may

+ * of access or the client to which the token was issued.
+ *
+ * Such authorization details should be enforced separately from authentication.
+ * Because Passport deals only with the latter, this is the responsiblity of
+ * middleware or routes further along the chain.  However, it is not optimal to
+ * decode the same data or execute the same database query later.  To avoid
+ * this, Passport accepts optional `info` along with the authenticated `user`
+ * in a strategy's `success()` action.  This info is set at `req.authInfo`,
+ * where said later middlware or routes can access it.
+ *
+ * Optionally, applications can register transforms to proccess this info,
+ * which take effect prior to `req.authInfo` being set.  This is useful, for
+ * example, when the info contains a client ID.  The transform can load the
+ * client from the database and include the instance in the transformed info,
+ * allowing the full set of client properties to be convieniently accessed.
+ *
+ * If no transforms are registered, `info` supplied by the strategy will be left
+ * unmodified.

+/**
+ * Passport initialization.
+ *
+ * Intializes Passport for incoming requests, allowing authentication strategies

+ * If sessions are being utilized, applications must set up Passport with
+ * functions to serialize a user into and out of a session.  For example, a
+ * common pattern is to serialize just the user ID into the session (due to the
+ * fact that it is desirable to store the minimum amount of data in a session).
+ * When a subsequent request arrives for the session, the full User object can
+ * be loaded from the database by ID.
+ *
+ * Note that additional middleware is required to persist login state, so we
+ * must use the `connect.session()` middleware _before_ `passport.initialize()`.
+ *
+ * If sessions are being used, this middleware must be in use by the
+ * Connect/Express application for Passport to operate.  If the application is
+ * entirely stateless (not using sessions), this middleware is not necessary,
+ * but its use will not have any adverse impact.
+ *
+ * Examples:
+ *
+ *     app.use(connect.cookieParser());
+ *     app.use(connect.session({ secret: 'keyboard cat' }));
+ *     app.use(passport.initialize());

+
+Generate strong pseudo-random bytes.
+
+This module is a simple wrapper around the Node.js core `crypto.randomBytes` API,
+with the following additions:
+
+  * A `Promise` interface for environments with promises.
+  * For Node.js versions that do not wait for the PRNG to be seeded, this module
+    will wait a bit.
+
+## Installation
+
+```sh
+$ npm install random-bytes
+```
+
+## API
+
+```js
+var randomBytes = require('random-bytes')
+```
+
+### randomBytes(size, callback)
+
+Generates strong pseudo-random bytes. The `size` argument is a number indicating
+the number of bytes to generate.
+
+```js
+randomBytes(12, function (error, bytes) {
+  if (error) throw error
+  // do something with the bytes
+})
+```
+
+### randomBytes(size)
+
+Generates strong pseudo-random bytes and return a `Promise`. The `size` argument is
+a number indicating the number of bytes to generate.
+
+**Note**: To use promises in Node.js _prior to 0.12_, promises must be
+"polyfilled" using `global.Promise = require('bluebird')`.
+
+```js
+randomBytes(18).then(function (string) {
+  // do something with the string
+})
+```
+
+### randomBytes.sync(size)
+
+A synchronous version of above.
+
+```js
+var bytes = randomBytes.sync(18)
+```

+# RNDM
+
+Random string generator.
+Basically `Math.random().toString(36).slice(2)`,
+but with both upper and lower case letters and arbitrary lengths.
+Useful for creating fast, not cryptographically secure salts.
+
+## API
+
+```js
+// base62 by default
+var rndm = require('rndm')
+var salt = rndm(16)
+```
+
+### var salt = rndm(length)
+

+# Timing safe string compare using double HMAC

+
+
+Prevents [timing attacks](http://codahale.com/a-lesson-in-timing-attacks/) using Brad Hill's
+[Double HMAC pattern](https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2011/february/double-hmac-verification/)
+to perform secure string comparison. Double HMAC avoids the timing atacks by blinding the
+timing channel using random time per attempt comparison against iterative brute force attacks.
+
+
+## Install
+
+```
+npm install tsscmp
+```
+## Why
+To compare secret values like **authentication tokens**, **passwords** or
+**capability urls** so that timing information is not
+leaked to the attacker.
+
+## Example
+
+```js
+var timingSafeCompare = require('tsscmp');
+
+var sessionToken = '127e6fbfe24a750e72930c';
+var givenToken = '127e6fbfe24a750e72930c';
+
+if (timingSafeCompare(sessionToken, givenToken)) {
+  console.log('good token');
+} else {
+  console.log('bad token');
+}
+```

+and [uid2](https://www.npmjs.com/package/uid2) whose UIDs are actually skewed
+due to the use of `%` and unnecessarily truncate the UID.
+Use this if you could still use UIDs with `-` and `_` in them.
+
+## Installation
+
+```sh
+$ npm install uid-safe
+```
+
+## API
+
+```js
+var uid = require('uid-safe')
+```
+
+### uid(byteLength, callback)
+
+Asynchronously create a UID with a specific byte length. Because `base64`
+encoding is used underneath, this is not the string length. For example,
+to create a UID of length 24, you want a byte length of 18.
+
+```js
+uid(18, function (err, string) {
+  if (err) throw err
+  // do something with the string
+})
+```
+
+### uid(byteLength)
+
+Asynchronously create a UID with a specific byte length and return a
+`Promise`.
+
+**Note**: To use promises in Node.js _prior to 0.12_, promises must be
+"polyfilled" using `global.Promise = require('bluebird')`.
+
+```js
+uid(18).then(function (string) {
+  // do something with the string
+})
+```
+
+### uid.sync(byteLength)
+
+A synchronous version of above.
+
+```js
+var string = uid.sync(18)
+```
