This PR introduces JWT (JSON Web Token) authentication for Stirling-PDF,
allowing for stateless authentication capabilities alongside the
existing session-based authentication system.
### Key Features & Changes
JWT Authentication System
- Core Service: JwtService.java - Token generation, validation, and
cookie management
- Authentication Filter: JwtAuthenticationFilter.java - Request
interceptor for JWT validation
- Key Management: KeyPersistenceService.java +
KeyPairCleanupService.java - RSA key rotation and persistence
- Frontend: jwt-init.js - Client-side JWT handling and URL cleanup
Security Integration
- SAML2: JwtSaml2AuthenticationRequestRepository.java - JWT-backed SAML
request storage
- OAuth2: Updated CustomAuthenticationSuccessHandler. java,
CustomOAuth2AuthenticationSuccessHandler.java &
CustomSaml2AuthenticationSuccessHandler.java for JWT integration
- Configuration: Enhanced SecurityConfiguration.java with JWT filter
chain
Infrastructure
- Caching: CacheConfig.java - Caffeine cache for JWT keys
- Database: New JwtVerificationKey.java entity for key storage
- Error Handling: JwtAuthenticationEntryPoint.java for unauthorized
access
### Challenges Encountered
- Configured SecurityConfiguration to use either
`UsernamePasswordAuthenticationFilter` or `JWTAuthenticationFilter`
based on whether JWTs are enabled to prevent the former intercepting
requests while in stateless mode.
- Removed the `.defaultSuccessUrl("/")` from login configuration as its
inclusion was preventing overriding the use of the
`CustomAuthenticationSuccessHandler` and preventing proper
authentication flows.

Stirling-PDF
Stirling-PDF is a robust, locally hosted web-based PDF manipulation tool using Docker. It enables you to carry out various operations on PDF files, including splitting, merging, converting, reorganizing, adding images, rotating, compressing, and more. This locally hosted web application has evolved to encompass a comprehensive set of features, addressing all your PDF requirements.
All files and PDFs exist either exclusively on the client side, reside in server memory only during task execution, or temporarily reside in a file solely for the execution of the task. Any file downloaded by the user will have been deleted from the server by that point.
