+
+## Cookies
+
+[`Cookies`] is an important, built-in request guard: it allows you to get, set,
+and remove cookies. Because `Cookies` is a request guard, an argument of its
+type can simply be added to a handler:
+
+```rust
+use rocket::http::Cookies;
+
+#[get("/")]
+fn index(cookies: Cookies) -> Option<String> {
+    cookies.get("message")
+        .map(|value| format!("Message: {}", value))
+}
+```
+
+This results in the incoming request's cookies being accessible from the
+handler. The example above retrieves a cookie named `message`. Cookies can also
+be set and removed using the `Cookies` guard. The [cookies example] on GitHub
+illustrates further use of the `Cookies` type to get and set cookies, while the
+[`Cookies`] documentation contains complete usage information.
+
+[cookies example]: https://github.com/SergioBenitez/Rocket/tree/v0.2.8/examples/cookies
+
+### Private Cookies
+
+Cookies added via the [`Cookies::add()`] method are set _in the clear._ In other
+words, the value set is visible by the client. For sensitive data, Rocket
+provides _private_ cookies.
+
+Private cookies are just like regular cookies except that they are encrypted
+using authenticated encryption, a form of encryption which simultaneously
+provides confidentiality, integrity, and authenticity. This means that private
+cookies cannot be inspected, tampered with, or manufactured by clients. If you
+prefer, you can think of private cookies as being signed and encrypted.
+
+The API for retrieving, adding, and removing private cookies is identical except
+methods are suffixed with `_private`. These methods are: [`get_private`],
+[`add_private`], and [`remove_private`]. An example of their usage is below:
+
+```rust
+/// Retrieve the user's ID, if any.
+#[get("/user_id")]
+fn user_id(cookies: Cookies) -> Option<String> {
+   request.cookies()
+      .get_private("user_id")
+      .map(|cookie| format!("User ID: {}", cookie.value()))
+}
+
+/// Remove the `user_id` cookie.
+#[post("/logout")]
+fn logout(mut cookies: Cookies) -> Flash<Redirect> {
+    cookies.remove_private(Cookie::named("user_id"));
+    Flash::success(Redirect::to("/login"), "Successfully logged out.")
+}
+```
+
+[`Cookies::add()`]: https://api.rocket.rs/rocket/http/enum.Cookies.html#method.add
+
+### Secret Key
+
+To encrypt private cookies, Rocket uses the 256-bit key specified in the
+`secret_key` configuration parameter. If one is not specified, Rocket will
+automatically generate a fresh key. Note, however, that a private cookie can
+only be decrypted with the same key with which it was encrypted. As such, it is
+important to set a `secret_key` configuration parameter when using private
+cookies so that cookies decrypt properly after an application restart. Rocket
+emits a warning if an application is run in production without a configured
+`secret_key`.
+
+Generating a string suitable for use as a `secret_key` configuration value is
+usually done through tools like `openssl`. Using `openssl`, a 256-bit base64 key
+can be generated with the command `openssl rand -base64 32`.
+
+For more information on configuration, see the
+[Configuration](/guide/configuration) section of the guide.
+
+[`get_private`]: https://api.rocket.rs/rocket/http/enum.Cookies.html#method.get_private
+[`add_private`]: https://api.rocket.rs/rocket/http/enum.Cookies.html#method.add_private
+[`remove_private`]: https://api.rocket.rs/rocket/http/enum.Cookies.html#method.remove_private
+
+### One-At-A-Time
+
+For safety reasons, Rocket currently requires that at most one `Cookies`
+instance be active at a time. It's uncommon to run into this restriction, but it
+can be confusing to handle if it does crop up.
+
+If this does happen, Rocket will emit messages to the console that look as
+follows:
+
+```
+=> Error: Multiple `Cookies` instances are active at once.
+=> An instance of `Cookies` must be dropped before another can be retrieved.
+=> Warning: The retrieved `Cookies` instance will be empty.
+```
+
+The messages will be emitted when a violating handler is called. The issue can
+be resolved by ensuring that two instances of `Cookies` cannot be active at once
+due to the offending handler. A common error is to have a handler that uses a
+`Cookies` request guard as well as a `Custom` request guard that retrieves
+`Cookies`, as so:
+
+```rust
+#[get("/")]
+fn bad(cookies: Cookies, custom: Custom) { .. }
+```
+
+Because the `cookies` guard will fire before the `custom` guard, the `custom`
+guard will retrieve an instance of `Cookies` when one already exists for
+`cookies`. This scenario can be fixed by simply swapping the order of the
+guards:
+
+```rust
+#[get("/")]
+fn good(custom: Custom, cookies: Cookies) { .. }
+```
 
 ## Body Data
 
 At some point, your web application will need to process body data. Data
