Struct cookie::SignedJar

pub struct SignedJar<'a> { /* fields omitted */ }

A child cookie jar that authenticates its cookies.

A signed child jar signs all the cookies added to it and verifies cookies retrieved from it. Any cookies stored in a SignedJar are assured integrity and authenticity. In other words, clients cannot tamper with the contents of a cookie nor can they fabricate cookie values, but the data is visible in plaintext.

This type is only available when the secure feature is enabled.

Methods

impl<'a> SignedJar<'a>

pub fn get(&self, name: &str) -> Option<Cookie<'static>>

Returns a reference to the Cookie inside this jar with the name name and verifies the authenticity and integrity of the cookie's value, returning a Cookie with the authenticated value. If the cookie cannot be found, or the cookie fails to verify, None is returned.

Example

use cookie::{CookieJar, Cookie, Key};

let key = Key::generate();
let mut jar = CookieJar::new();
let mut signed_jar = jar.signed(&key);
assert!(signed_jar.get("name").is_none());

signed_jar.add(Cookie::new("name", "value"));
assert_eq!(signed_jar.get("name").unwrap().value(), "value");

pub fn add(&mut self, cookie: Cookie<'static>)

Adds cookie to the parent jar. The cookie's value is signed assuring integrity and authenticity.

Example

use cookie::{CookieJar, Cookie, Key};

let key = Key::generate();
let mut jar = CookieJar::new();
jar.signed(&key).add(Cookie::new("name", "value"));

assert_ne!(jar.get("name").unwrap().value(), "value");
assert!(jar.get("name").unwrap().value().contains("value"));
assert_eq!(jar.signed(&key).get("name").unwrap().value(), "value");

pub fn add_original(&mut self, cookie: Cookie<'static>)

Adds an "original" cookie to this jar. The cookie's value is signed assuring integrity and authenticity. Adding an original cookie does not affect the CookieJar::delta() computation. This method is intended to be used to seed the cookie jar with cookies received from a client's HTTP message.

For accurate delta computations, this method should not be called after calling remove.

Example

use cookie::{CookieJar, Cookie, Key};

let key = Key::generate();
let mut jar = CookieJar::new();
jar.signed(&key).add_original(Cookie::new("name", "value"));

assert_eq!(jar.iter().count(), 1);
assert_eq!(jar.delta().count(), 0);

pub fn remove(&mut self, cookie: Cookie<'static>)

Removes cookie from the parent jar.

For correct removal, the passed in cookie must contain the same path and domain as the cookie that was initially set.

See CookieJar::remove for more details.

Example

use cookie::{CookieJar, Cookie, Key};

let key = Key::generate();
let mut jar = CookieJar::new();
let mut signed_jar = jar.signed(&key);

signed_jar.add(Cookie::new("name", "value"));
assert!(signed_jar.get("name").is_some());

signed_jar.remove(Cookie::named("name"));
assert!(signed_jar.get("name").is_none());
