+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ 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.
+
+##### cookie.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.
+
+##### cookie.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.
+
+##### cookie.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`.
+
+##### 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.
+
+##### cookie.path
+
+Specifies the value for the `Path` `Set-Cookie`. By default, this is set to `'/'`, which
+is the root path of the domain.
+
+##### cookie.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.
+  - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
+  - `'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][rfc-6265bis-03-4.1.2.7].
+
+**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.
+
+##### cookie.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 the 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`.
+
+With this enabled, the session identifier cookie will expire in
+[`maxAge`](#cookiemaxage) since the last response was sent instead of in
+[`maxAge`](#cookiemaxage) since the session was last modified by the server.
+
+This is typically used in conjuction with short, non-session-length
+[`maxAge`](#cookiemaxage) values to provide a quick timeout of the session data
+with reduced potentional of it occurring during on going server interactions.
+
+**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. This option only modifies the behavior when an existing session was
+loaded for the request.
+
+##### 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) {
+  if (req.session.views) {
+    req.session.views++
+    res.setHeader('Content-Type', 'text/html')
+    res.write('<p>views: ' + req.session.views + '</p>')
+    res.write('<p>expires in: ' + (req.session.cookie.maxAge / 1000) + 's</p>')
+    res.end()
+  } else {
+    req.session.views = 1
+    res.end('welcome to the session demo. refresh!')
+  }
+})
+```
+
+#### Session.regenerate(callback)
+
+To regenerate the session simply invoke the method. Once complete,
+a new SID and `Session` instance will be initialized at `req.session`
+and the `callback` will be invoked.
+
+```js
+req.session.regenerate(function(err) {
+  // will have a new session here
+})
+```
+
+#### Session.destroy(callback)
+
+Destroys the session and will unset the `req.session` property.
+Once complete, the `callback` will be invoked.
+
+```js
+req.session.destroy(function(err) {
+  // cannot access session here
+})
+```
+
+#### Session.reload(callback)
+
+Reloads the session data from the store and re-populates the
+`req.session` object. Once complete, the `callback` will be invoked.
+
+```js
+req.session.reload(function(err) {
+  // session updated
+})
+```
+
+#### Session.save(callback)
+
+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,
+redirects, 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 is an
+alias of [`req.sessionID`](#reqsessionid-1) and cannot be modified.
+It has been added to make the session ID accessible from the `session`
+object.
+
+### 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.cookie.maxAge` to its original value.
+
+```js
+req.session.cookie.maxAge // => 30000
+```
+
+#### Cookie.originalMaxAge
+
+The `req.session.cookie.originalMaxAge` property returns the original
+`maxAge` (time-to-live), in milliseconds, of the session cookie.
+
+### 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.

+
+## Example
+
+A simple example using `express-session` to store page views for a user.
+
+```js
+var express = require('express')
+var parseurl = require('parseurl')
+var session = require('express-session')
+
+var app = express()
+
+app.use(session({
+  secret: 'keyboard cat',
+  resave: false,
+  saveUninitialized: true
+}))
+
+app.use(function (req, res, next) {
+  if (!req.session.views) {
+    req.session.views = {}
+  }
+
+  // get the url pathname
+  var pathname = parseurl(req).pathname
+
+  // count the views
+  req.session.views[pathname] = (req.session.views[pathname] || 0) + 1
+
+  next()
+})
+
+app.get('/foo', function (req, res, next) {
+  res.send('you viewed this page ' + req.session.views['/foo'] + ' times')
+})
+
+app.get('/bar', function (req, res, next) {
+  res.send('you viewed this page ' + req.session.views['/bar'] + ' times')
+})
+```
+
+## Debugging
+
+This module uses the [debug](https://www.npmjs.com/package/debug) module
+internally to log information about session operations.
+
+To see all the internal logs, set the `DEBUG` environment variable to
+`express-session` when launching your app (`npm start`, in this example):
+
+```sh
+$ DEBUG=express-session npm start
+```
+
+On Windows, use the corresponding command;
+
+```sh
+> set DEBUG=express-session & npm start
+```

+Deprecate all the things
+
+> With great modules comes great responsibility; mark things deprecated!
+
+## Install
+
+This module is installed directly using `npm`:
+
+```sh
+$ npm install depd
+```
+
+This module can also be bundled with systems like
+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
+though by default this module will alter it's API to no longer display or
+track deprecations.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan
+|              |          |           |

+namespace      |          |           location of mycoolmod.oldfunction() call
+               |          deprecation message
+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```
+Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22

+|                             |              |          |              |
+timestamp of message          namespace      |          |             location of mycoolmod.oldfunction() call
+                                             |          deprecation message
+                                             the word "deprecated"
+```
+
+## Examples
+
+### Deprecating all calls to a function
+
+This will display a deprecated message about "oldfunction" being deprecated
+from "my-module" on STDERR.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction () {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+[Get supported safe-buffer with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-safe-buffer?utm_source=npm-safe-buffer&utm_medium=referral&utm_campaign=readme)
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).

+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+Execute a listener when a response is about to write headers.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```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!')
+}
+```
+

+
+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)
+```

+
+URL and cookie safe UIDs
+
+Create cryptographically secure UIDs safe for both cookie and URL usage.
+This is in contrast to modules such as [rand-token](https://www.npmjs.com/package/rand-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)
+```
