Learn Json Web Tokens
This project is a technical tutorial and guide for implementing user identity and session management using JSON Web Tokens. It focuses on building a secure login system that verifies user identities in web and mobile applications.
The material covers the full lifecycle of token-based security, including the issuance and validation of authentication tokens and the management of stateless sessions. It provides instructions on maintaining persistent user sessions through client-side storage and implementing session revocation to invalidate specific or all active tokens.
The implementation details include the use of signed cryptographic tokens with embedded identity claims and expiration timestamps. It further addresses token authenticity through signature validation and the use of database-backed blacklisting to override statelessness for invalidated sessions.
Features
- Authentication Tutorials - Provides a comprehensive technical guide and tutorial for implementing user identity and session management using JSON Web Tokens.
- JWT Authentications - Provides a complete guide for implementing a secure login system using JSON Web Tokens.
- Token and Session Management - Generates signed tokens containing user claims and expiration dates for session management.
- JWT Session Management - Offers detailed instructions for the full lifecycle of JWT-based session management, including issuance, validation, and invalidation.
- JWT Token Validators - Implements validation of JWT signatures and expiration to protect API endpoints.
- Session Token Validation - Verifies the signature and expiration of tokens found in request headers to authorize users.
- Token Blacklists - Implements a database-backed blacklist to revoke specific tokens and override the stateless nature of JWTs.
- Token Invalidation - Allows marking individual tokens as invalid in a database to prevent further unauthorized access.
- Stateless Session Management - Implements a session management architecture that avoids server-side state using signed tokens.
- Token Authentication - Issues signed cryptographic tokens after authentication to verify user identity in subsequent requests.
- Session Token Issuance - Provides logic for issuing signed session tokens to maintain user identity after successful authentication.
- Token-Based Identity Verifications - Provides a technical walkthrough for confirming user identities using cryptographically signed tokens and client-side storage.
- Stateless Token Validation - Implements stateless authentication by validating signed tokens locally without querying a session store.
- Token Authenticity Verifications - Validates token signatures and timestamps to ensure requests originate from a trusted source.
- Secure Client-Side Session Storages - Implements secure storage of tokens using HttpOnly and Secure cookie flags.
- Hash-Based Signature Verifiers - Ensures token integrity through HMAC-based signature validation of the payload and secret.
- Claim Struct Embeddings - Implements embedding of user metadata and expiration timestamps within the JWT payload to reduce database dependency.
- Session-Cookie Persistences - Provides mechanisms for maintaining user sessions by persisting signed tokens in browser cookies.
- Local Storage Token Persisters - Manages the saving and clearing of identity tokens within browser local storage.
- Token Revocation - Implements mechanisms to invalidate active authentication tokens to force re-authentication or handle security breaches.
- Expiring Tokens - Secures sessions by embedding expiration claims that automatically invalidate tokens after a set time.
- JWT and Token Management - Educational resource for implementing JWT-based web security.
