The "FileUpload Gunner" project appears to be a specialized tool or repository likely focused on file upload security and automation, potentially associated with security researchers like Gunnar Aastrand Grimnes or general security testing frameworks.

While implementations may vary based on specific versions, most FileUpload Gunner iterations include several high-performance features: fileupload gunner project

Key Features

  • Resumable uploads using chunk IDs and offsets.
  • Client-side SHA-256 hashing per chunk and file-level verification on assembly.
  • Optional client-side encryption with per-file keys managed via KMS.
  • Idempotency keys for safe retries.
  • Rate limiting and throttling via API gateway.
  • Automatic multipart upload orchestration for S3 backends.
  • Web UI for monitoring active uploads and retrying failed sessions.

Implementation roadmap (12-week example)

  • Week 1–2: Design APIs, data model, and auth/token scheme.
  • Week 3–4: Implement basic session lifecycle and chunk upload (local filesystem adapter).
  • Week 5–6: Add resumable logic, client SDK (browser + CLI), and checksums.
  • Week 7–8: Integrate S3 adapter, multipart/compose flow, finalize/assembly worker.
  • Week 9: Add client-side encryption option and signed URLs.
  • Week 10: Add antivirus integration and validation pipeline.
  • Week 11: Observability, metrics, and automated tests/fuzzing.
  • Week 12: Load testing, hardening, and documentation.
