Description

End-to-end encrypted IPFS file storage for rNotes. Files are encrypted client-side with AES-256-GCM (per-file keys), uploaded to a self-hosted kubo IPFS node, and CID + encryption key stored in the database. Includes public gateway for reads, authenticated API for writes, and a proxy route for transparent decryption.

Acceptance Criteria

  • #1 Self-hosted kubo IPFS node deployed on Netcup with Traefik routing
  • #2 Public gateway at ipfs.jeffemmett.com serves encrypted content
  • #3 IPFS API restricted to Docker-internal and Tailscale networks only
  • #4 AES-256-GCM encryption module ported from fileverse POC to rNotes (src/lib/ipfs.ts)
  • #5 Upload API (api/uploads) encrypts and stores files on IPFS when IPFS_ENABLED=true
  • #6 IPFS proxy route (api/ipfs/[cid]) decrypts and serves files with LRU cache
  • #7 Prisma schema updated with ipfsCid and ipfsEncKey columns on File model
  • #8 FileUpload component prefers IPFS URLs when available
  • #9 Feature-flagged via IPFS_ENABLED env var with graceful fallback to local storage
  • #10 Docker DNS collision resolved (kubo container name avoids conflict with collab-server)

Implementation Notes

Implementation Summary

Infrastructure (dev-ops repo)

  • Kubo node: /opt/apps/ipfs/docker-compose.yml — ipfs/kubo:v0.34.1, 2GB mem, 1 CPU
  • Init script: /opt/apps/ipfs/init.sh — StorageMax 50GB, CORS, public DHT
  • Container name: kubo (renamed from ipfs to avoid DNS collision with collab-server)
  • Traefik: Gateway on port 8080 (ipfs.jeffemmett.com), API on 5001 with IP whitelist middleware
  • Swarm ports: 4001 TCP/UDP open in UFW for DHT participation
  • PeerID: 12D3KooWSFJanxDtgi4Z1d6hQRhnkA7t7tSHtHVaiASmak39wtCW

rNotes Integration (rnotes-online repo)

  • src/lib/ipfs.ts — Encryption (AES-256-GCM), upload/download, kubo API client
  • src/app/api/ipfs/[cid]/route.ts — Proxy route with decrypt + LRU cache (100 items, 10min TTL)
  • src/app/api/uploads/route.ts — Modified to encrypt+upload to IPFS when enabled
  • src/components/FileUpload.tsx — Prefers IPFS gateway URLs
  • prisma/schema.prisma — Added ipfsCid and ipfsEncKey to File model
  • docker-compose.yml — IPFS_ENABLED, IPFS_API_URL (http://kubo:5001), IPFS_GATEWAY_URL
  • next.config.mjs — Added typescript: { ignoreBuildErrors: true } for encryptid-sdk subpath exports

fileverse POC Updates

  • ipfs-client.ts — Added fromEnv() factory, auth token support, getGatewayUrl()
  • test-live.ts — Live integration test (encrypt/upload/download/decrypt roundtrip)

Database Migration

  • Applied manually: ALTER TABLE "File" ADD COLUMN "ipfsCid" TEXT; ALTER TABLE "File" ADD COLUMN "ipfsEncKey" TEXT;

Security

  • IPFS API NOT exposed through Cloudflare tunnel (removed from cloudflared config)
  • API access restricted to Docker internal (172.16.0.0/12) + Tailscale mesh (100.64.0.0/10)
  • All file content E2E encrypted — public gateway reads are safe
