Iron Session
iron-session 是一个用于 JavaScript 的无状态会话管理库，将加密和签名后的会话数据直接存储在浏览器 Cookie 中。它作为身份验证中间件，无需服务器端数据库或网络查找即可验证用户身份。
该项目提供了一个支持版本化密码轮换的对称密钥加密工具。这允许在不使现有用户会话失效的情况下更新系统中的加密密钥。
除了会话管理外，该库还包含将任意数据对象密封为安全签名字符串并解封的实用程序，以确保内容未被篡改。这些功能支持生成安全令牌和魔术登录链接。
Features
- Cookie-Based Session Management - Implements session management by storing encrypted and signed data directly in browser cookies.
- Stateless Session Management - Implements a stateless session system that stores encrypted data in cookies to eliminate server-side database lookups.
- Cookie-Based Stores - Uses cookies as stores for encrypted application state to prevent client-side tampering.
- Cryptographic Signing Methods - Provides cryptographic signing to ensure the integrity and authenticity of session data.
- Digital Message Signing - Produces cryptographic signatures for session data to prevent tampering.
- Cookie-Based Session Storage - Provides a storage mechanism that persists application state in the browser using symmetric encryption and signing.
- Session & Cookie Handlers - Handles the reading and setting of encrypted browser cookies to persist user state.
- Session Cookie Authentications - Uses encrypted browser cookies as a secure storage mechanism to maintain user sessions.
- Symmetric Encryption - Uses symmetric encryption with a shared secret to maintain session data confidentiality.
- Stateless Architectures - Enables request processing without server-side session state by decoding data from cookies.
- Authentication Middlewares - Provides authentication middleware for JavaScript applications to verify identity via cryptographically sealed cookies.
- Cryptographic Data Sealing - Combines encryption and signing to seal arbitrary data objects into secure strings for tokens.
- Cryptographic Unsealing - Verifies signed strings to decode original data and ensure it has not been tampered with.
- Versioned Password Rotation - Supports versioned password rotation to update encryption keys without forcing active users to re-authenticate.
- Versioned Key Rotations - Supports updating encryption keys using a versioned history to avoid invalidating active sessions.
- Session Lifecycle Management - Manages the creation, rotation, and expiration of cryptographically secured sessions.
- User Session Termination - Provides the ability to programmatically terminate user sessions by removing the session cookie.
- Token Generation - Generates cryptographically secure encrypted strings for use in magic links and access tokens.
- Authentication Workflows - Provides a secure authentication and state persistence workflow specifically for Next.js applications.
