# TODO

Unstructured intake buffer for ideas, issues, and observations. Items here are raw and unrefined. Actionable items should be promoted to TASKLIST.md.

## Ideas

- Paste compression for large text content
  - Must mark compression in URL fragment (e.g., `#z:<key>` or `#<key>:z`)
  - Receiver needs to know content is compressed before decryption
  - Design: compress-then-encrypt only (not compress-only)
  - Compressed data has high entropy → bypasses entropy enforcement
  - Must enforce encryption when compression enabled (CLI-side)
  - Server rejects plaintext via REQUIRE_BINARY (UTF-8 detection)
- ETag support for conditional requests
- Neovim/Vim plugin for editor integration
- Webhook notifications for paste events
- Certificate renewal reminder in CLI
- Admin endpoint for CA key rotation
- Clipboard integration (pbcopy/xclip)

## Observations

- Shell completions already implemented (`fpaste completion --shell bash/zsh/fish`)
- Mypy type errors fixed: now enforced in CI (was informational)
- CI enhanced: security-tests job, SBOM generation (CycloneDX), memory leak checks
- Comprehensive pentest plan completed (PENTEST_PLAN.md) - all remediations implemented
- PKI uses AES-256-GCM for CA private key encryption (PBKDF2 key derivation)
- SHA1 fingerprints are X.509 standard, not security-relevant (usedforsecurity=False)
- Revoked certificates are soft-deleted (status tracked, not removed)
- CI pipeline: lint runs parallel with security, tests wait for lint
- Ruff replaces flake8/isort/pyupgrade with single fast tool
- Bandit configured for medium+ severity only (-ll flag)
- PKI audit events now logged: CERT_ISSUED, CERT_REVOKED, AUTH_FAILURE
- Request duration metrics recorded via Prometheus histogram
- Memory leak tests use tracemalloc to detect leaks (CI job)
- Rate limit headers (X-RateLimit-*) on both 201 and 429 responses
- systemd service unit with security hardening in examples/

## Questions

- Certificate renewal: reissue with same CN or require new request?
- Should revoked certs be purged after grace period?

## Resolved

- Expired paste cleanup runs in-process via before_request hook (no cron needed)

## Debt

- Create Ansible deployment role (Kubernetes manifests complete)

## External Dependencies

- cryptography package required for PKI features (optional otherwise)
- For full MIME detection, consider `filetype` library (currently text/binary only)
