This repository is a .NET library for JWT (JSON Web Token) key management that provides automatic generation and rotation of cryptographic keys for JWT signing (JWS) and encryption (JWE). It features a modular architecture with a core library handling key generation/storage, multiple storage providers (in-memory, file system, Entity Framework Core), and framework-specific integrations for ASP.NET Core and IdentityServer4. The library exposes a JWKS endpoint for sharing public keys and integrates with ASP.NET Core authentication systems to validate tokens using the managed keys. Key entry points include the AddJwksManager() service registration method, UseJwksDiscovery() middleware for the JWKS endpoint, and the IJwtService interface for token generation and validation. The primary data flow involves generating cryptographic keys, storing them via pluggable storage providers, retrieving current keys for token operations, and exposing public keys through the JWKS endpoint. The library depends on System.IdentityModel.Tokens.Jwt for JWT handling, Microsoft.AspNetCore.DataProtection for key protection in the default storage implementation, and various Microsoft.Extensions packages for caching, options, and logging.
