Crate cookie

HTTP cookie parsing and cookie jar management.

This crates provides the Cookie type, representing an HTTP cookie, and the CookieJar type, which manages a collection of cookies for session management, recording changes as they are made, and optional automatic cookie encryption and signing.

Usage

Add the following to the [dependencies] section of your Cargo.toml:

cookie = "0.16"

Features

This crate exposes several features, all of which are disabled by default:

• percent-encode

  Enables percent encoding and decoding of names and values in cookies.

  When this feature is enabled, the Cookie::encoded() and Cookie::parse_encoded() methods are available. The encoded method returns a wrapper around a Cookie whose Display implementation percent-encodes the name and value of the cookie. The parse_encoded method percent-decodes the name and value of a Cookie during parsing.

• signed

  Enables signed cookies via [CookieJar::signed()].

  When this feature is enabled, the [CookieJar::signed()] method, [SignedJar] type, and [Key] type are available. The jar acts as “child jar”; operations on the jar automatically sign and verify cookies as they are added and retrieved from the parent jar.

• private

  Enables private (authenticated, encrypted) cookies via [CookieJar::private()].

  When this feature is enabled, the [CookieJar::private()] method, [PrivateJar] type, and [Key] type are available. The jar acts as “child jar”; operations on the jar automatically encrypt and decrypt/authenticate cookies as they are added and retrieved from the parent jar.

• key-expansion

  Enables key expansion or key derivation via [Key::derive_from()].

  When this feature is enabled, and either signed or private are also enabled, the [Key::derive_from()] method is available. The method can be used to derive a Key structure appropriate for use with signed and private jars from cryptographically valid key material that is shorter in length than the full key.

• secure

  A meta-feature that simultaneously enables signed, private, and key-expansion.

You can enable features via Cargo.toml:

[dependencies.cookie]
features = ["secure", "percent-encode"]

Modules

• time
  Feature flags

Structs

  Representation of an HTTP cookie.
• CookieBuilder
  Structure that follows the builder pattern for building Cookie structs.
• CookieJar
  A collection of cookies that tracks its modifications.
