WebAuthn (Web Authentication) is a W3C standard that enables secure, passwordless, and phishing-resistant authentication using public-key cryptography. It's widely used with passkeys to improve security and user experience. However, authenticating users with WebAuthn is just the first step — after successful authentication, you often need to author...

TsgcWebSocketServer is part of the sgcWebSockets suite and provides a high-level component for creating WebSocket servers in C++Builder.

The TsgcWSAPIServer_WebAuthn component is a Delphi/FPC server module that implements the relying‑party side of the WebAuthn protocol over HTTPS. It integrates with TsgcWebSocketHTTPServer or TsgcWebSocketServer, and it exposes REST‑like endpoints for registration and authentication.  Endpoint Mechanics By default, the component registers ...

WebAuthn is the authentication layer of the FIDO2 standard. Instead of depending on user‑remembered secrets, it employs asymmetric cryptography. During registration, a user's authenticator (hardware key, secure enclave, TPM, etc.) generates a private–public key pair scoped to the relying party domain. The browser sends the public key and attestatio...

TsgcWebSocketClient is the .NET wrapper around the sgcWebSockets runtime client.
