A comprehensive reference implementation demonstrating browser identity management using non-exportable WebCrypto keys and DPoP (Demonstration of Proof-of-Possession) tokens for advanced cryptographic security.
Browser-bound cryptographic identity using WebCrypto API. Keys are non-exportable and persist across browser sessions, but remain within the secure browser context. Not hardware-backed like HSM keys, but provides browser authentication within browser security model.
DPoP tokens with client and server signing for two-way verification, providing identity continuity and limiting account takeover attack vectors through cryptographic request binding.
Cross-device linking for step-up authentication and Corporate VDI environments. Enables secure session sharing between devices while maintaining cryptographic binding and preventing session hijacking.
Service worker request interception, secure headers, CSRF protection, and comprehensive input validation for enterprise-grade security.
