Secure Token Exchange & Cross-Platform Session Management
Technologies
Implementation of the LTI (Learning Tools Interoperability) protocol for secure integration between platforms, demonstrating complex authentication and authorization patterns.
Security Implementation
- **OAuth 2.0 Flow:** Complete implementation of the OAuth 2.0 authorization code flow with PKCE
- •**JWT Handling:** Secure JWT generation, validation, and parsing with proper signature verification
- •**Token Exchange:** Implementation of secure token exchange protocol for cross-platform authentication
- •**Signature Verification:** Request signing and verification using RSA keys
Technical Challenges Solved
1. **Cross-Platform Sessions:** Managing user sessions across multiple platforms with different authentication systems 2. **Token Security:** Implementing secure token storage, rotation, and revocation 3. **Deep Linking:** Supporting deep links with proper context preservation and security validation 4. **Error Handling:** Graceful handling of authentication failures with proper user feedback
This implementation required deep understanding of OAuth flows, JWT security, and cross-origin authentication patterns.
Key Highlights
- Implemented OAuth 2.0 authorization flow with PKCE
- Built secure token exchange and signature verification
