Supabase Storage: Server-Side File Encryption + Auth/RLS Integration (Pair-Work Support)

@AwaisChaudhry

Hello, I’m Muhammad Awais and I will build a server-side encryption pipeline for Supabase Storage with AES-256, keys kept on the server, never exposed to clients, and integrated with your Supabase Auth roles. Uploads will be encrypted before storage, stored as encrypted blobs, and decrypted only for authorised users. I’ll implement Storage rules and RLS tied to owner and roles, covering PDFs, DOCX, PNG, JPEG, WebP, and a clean path to extend. The README will describe REST and client-library usage for upload/list/download/decrypt, plus brief deployment notes. I’ll work in a live pair-programming style, sharing screens in short sessions to implement, debug, and harden the system together. 1) How do you want to handle encryption keys (KMS choice, rotation policy, offline access)? 2) Do you want per-file AES-256-GCM with unique IV per file and authenticated encryption including integrity checks? 3) How should RLS/policy tie to Supabase Auth roles and ownership (owner_id, role-based access)? 4) What file size limits and allowed MIME types should we enforce now and for future extension? 5) What is your target deployment environment for CI/CD (Supabase project, hosting) and preferred schedule for pair-programming sessions? Best regards,

As an experienced Software Engineer, my expertise in backend development and my proficiency in Python and Linux make me a strong fit for your project. I have a deep understanding of API development and software development, which are key skills required to implement your server-side encryption pipeline and handle secure key management. Additionally, my background in embedded systems ensures that I am highly detail-oriented and focused on efficiency, two qualities essential for developing your system in a scalable manner. One area of my particular interest that aligns well with your project needs is cryptographic algorithms. Having worked on firmware development projects requiring strong encryption and high-security standards, I am well-equipped to deliver the level of data protection you require. My experience not only includes implementing AES-256 encryption but also ensuring secrets are not exposed to clients for enhanced security.

Hi The core technical risk is implementing server-side AES-256 encryption with correct IV handling and integrity verification while ensuring keys never touch the client and Supabase policies enforce access. I can integrate directly with Supabase Auth and build a secure upload/download pipeline using Node.js/TypeScript, Supabase Storage, and Postgres RLS. On upload, I’ll encrypt files on the server (unique random IV per object), store only encrypted blobs in Storage, and write metadata (owner, role access, key reference, hash) into Postgres. For key management, I’ll keep secrets server-side only (KMS or env-backed master key with envelope encryption) and prevent hard-coded keys, IV reuse, or insecure CORS. RLS and Storage policies will be tied to Supabase Auth so unauthorised users get denied, and authorised users can list/download only what they own or are permitted to access. On retrieval, I’ll decrypt server-side with integrity checks (AEAD like AES-GCM or HMAC verification) before streaming back to the user securely. I’m comfortable working help-desk style via screenshare/pair-programming to implement, debug, and harden the solution with clean code and clear docs. Thanks, Hercules

Hello, I’m excited to assist with your encrypted file upload system. I’ll implement server-side AES-256 encryption for document and image uploads, ensuring files are stored in Supabase Storage as encrypted blobs. Access control will be managed via Supabase Auth, so only authorized users can decrypt their files based on roles and ownership. I’ll focus on secure key management, preventing any secrets from being exposed to the client, and implement storage rules with RLS tied to Supabase Auth. We’ll also build out the necessary pipelines to handle document (PDF/DOCX) and image (PNG/JPEG/WebP) formats, with future extensibility in mind. I’m happy to collaborate in a help-desk style through pair-programming, screensharing, and quick debugging sessions to ensure the system is secure and working smoothly. We’ll prioritize security, clean code, and clear communication throughout. Let’s discuss how we can move forward! Best regards, Juan

Hi there! Storing sensitive files without encryption risks data leaks, and mishandled keys can break your auth flow. Without tight integration, Supabase Auth + Storage could allow unauthorised access or accidental data exposure. I can implement AES-256 server-side encryption for uploads, manage keys securely, enforce RLS based on Supabase Auth roles, and ensure only authorised users can decrypt. We can work together via live support or pair-programming to implement, debug, and harden the system step by step. I’ve built secure file pipelines before where documents and images were encrypted end-to-end and fully auditable. Do you want me to start by designing the encryption + RLS workflow for your current Supabase setup? Start /Open chat now.
