Hi, I can help you implement robust PKI-based CSRF protection across your Spring service router using clean, production-ready Spring Security configuration. I’ll handle: PKI-backed CSRF validation that intercepts all requests (GET/POST/etc.) before controller logic Secure token issuance and refresh flow for upstream services/clients Server-side validation tied to session or stateless design to prevent replay attacks Immediate 403 handling for missing or invalid tokens via custom security filters Clean, readable code with unit tests and a short README covering setup, cert/key usage, and extension I’m comfortable working with Spring Security, x509/JWT-based security, custom filters, and crypto libraries, and I’ll keep the solution lean and future-proof. Once wired in, your acceptance tests should pass with only properly signed requests succeeding. Happy to review your current router setup and architecture diagrams and get started right away. Thanks, Abhay Kumar

Dear client! I have a lot of experience working with SpringBoot's RESTful API for the backend with Spring Security. I have experience developing a backend for currency exchange operations for a large bank. Also worked as a backend for the purchase/sale of securities in the same bank. Java development environment, SpringBoot, SwaggerUI. Used PostgreeSQL, Redis, RabbitMQ... I will be glad to cooperate with you Best regards, Vladimir

Hi! I was excited reading this because I’ve built Spring Boot security layers using PKI, x509, JWT, and custom Spring Security filters for high-trust service-to-service systems. I’d approach this by adding a custom OncePerRequestFilter wired into Spring Security to enforce PKI-signed CSRF tokens on every request, using certificate-backed signatures + nonce/timestamp binding (or stateless HMAC/JWT hybrid if preferred) to prevent replay clean, testable, and Boot-friendly. I’ll deliver well-documented config, unit tests, and a clear README covering key generation and extension. Happy to jump on a quick call to review your architecture diagrams I’ll walk you through similar work I’ve done and share relevant examples live. Best Regards Ibran Shafee

⚠️ IF YOU'RE NOT HAPPY YOU DON’T PAY ⚠️ Looks like you need airtight CSRF protection that works seamlessly with your Spring router without slowing things down. Handling PKI-signed tokens, blocking replay attacks, and making sure every request fails fast with a clean 403 can get messy especially when balancing stateless validation and readable architecture. I have worked with Spring Security filters, JWT/x509 flows, and secure API gateways, so integrating certificate checks, building a lean token flow, and delivering tested, maintainable code is right in my lane. I also focus on clear structure so adding new endpoints won’t break protection later. I would love to chat about your project! The worst that can happen is you walk away with a free consultation.

Hi ? I can implement PKI-backed CSRF protection across all Spring Boot endpoints using Spring Security. I’ll add a custom security filter that intercepts every request (GET/POST/etc.) and validates a signed CSRF token using your existing certificates (x509 / public-key verification). Invalid or missing tokens will be rejected immediately with 403 before any controller logic runs. Approach Spring Security filter chain with a custom CSRF verification filter Token bound to session or stateless (JWT + signature + nonce) to prevent replay attacks Lightweight token issuance/refresh endpoint for upstream services Clean, readable config with unit tests (MockMvc + SecurityContext) Deliverables Boot-compatible Spring Security config PKI integration using standard crypto libs (Java Security / Bouncy Castle if needed) Tests + README covering setup, cert generation, and extension guidelines I’ve worked with Spring Security, JWT, x509 auth, and custom filters, so integrating this into your router will be smooth and future-proof.
