## Description

This library provides a server-side implementation for the WebAuthn standard, enabling developers to integrate FIDO2-compliant authentication into applications. It functions as a toolkit for managing public-key infrastructure, allowing systems to verify user identity through hardware-backed cryptographic signatures rather than traditional passwords.

The framework facilitates the entire credential lifecycle, from the initial registration of security keys and biometric devices to the ongoing validation of authentication attempts. It handles the generation and verification of challenge-response handshakes, ensuring that each login event is protected against replay attacks and unauthorized access.

Beyond core identity verification, the library supports the implementation of multi-factor authentication flows and provides configurable settings to adjust security requirements. It processes authentication data using standardized binary serialization and payload formats to maintain interoperability with existing web security infrastructure.
