# FlaskPaste Roadmap
|
|
|
|
## Current State
|
|
|
|
FlaskPaste v1.2.0 is deployed with PKI integration and comprehensive security tooling.
|
|
|
|
**Implemented:**
|
|
- Full REST API (CRUD operations)
|
|
- Binary content support with magic-byte MIME detection
|
|
- Client certificate authentication
|
|
- Minimal PKI (CA generation, certificate issuance, revocation)
|
|
- Content-hash deduplication (abuse prevention)
|
|
- Proof-of-work spam prevention
|
|
- Entropy enforcement (require encrypted uploads)
|
|
- E2E encryption in CLI (AES-256-GCM, key in URL fragment)
|
|
- URL prefix support for reverse proxy deployments
|
|
- /client endpoint for CLI distribution
|
|
- Automatic paste expiry
|
|
- Burn-after-read pastes
|
|
- Custom expiry per paste
|
|
- Security headers and request tracing
|
|
- Container deployment support
|
|
- Security tooling (ruff, bandit, mypy, pip-audit)
|
|
- CI/CD pipeline with lint, security, and test jobs
|
|
- Comprehensive test suite (147 tests)
|
|
|
|
## Phase 1: Hardening (Complete)

└───┴─────────────────────────────────┴────────────────────────────────────┘
|
|
```
|
|
|
|
### PKI Features
|
|
|
|
Integrated certificate authority for mTLS:
|
|
- `POST /pki/ca` - Generate CA (first-run bootstrap)
|
|
- `GET /pki/status` - CA status and fingerprint
|
|
- `GET /pki/ca.crt` - Download CA certificate
|
|
- `POST /pki/issue` - Issue client certificate
|
|
- `POST /pki/revoke/<serial>` - Revoke certificate
|
|
- CLI: `fpaste pki status`, `fpaste pki issue`, `fpaste pki revoke`
|
|
|
|
## Phase 4: Ecosystem (In Progress)
|
|
|
|
Focus: Integration with external systems.
|
|
|
|
```
|
|
┌───┬─────────────────────────────────┬────────────────────────────────────┐
|
|
│ # │ Integration │ Status
|
|
├───┼─────────────────────────────────┼────────────────────────────────────┤
|
|
│ 1 │ CLI client (fpaste) │ Done (with E2E + PKI)
|
|
│ 2 │ /client endpoint │ Done (downloadable CLI)
|
|
│ 3 │ Ansible deployment role │ Planned
|
|
│ 4 │ Kubernetes manifests │ Planned
|
|
│ 5 │ Shell aliases/functions │ Planned
|
|
└───┴─────────────────────────────────┴────────────────────────────────────┘
|
|
```
|
|
|
|
### CLI Client (Complete)
|
|
|
|
Standalone Python CLI with encryption and PKI support:
|
|
- `fpaste create file.txt` - Create paste from file
|
|
- `fpaste create -e file.txt` - Create encrypted paste (E2E)
|
|
- `fpaste get <id>` - Get paste (auto-decrypts with URL fragment key)
|
|
- `fpaste delete <id>` - Delete paste
|
|
- `fpaste info` - Show server info
|
|
- `fpaste pki status` - Show PKI status
|
|
- `fpaste pki issue -n "name"` - Request client certificate
|
|
- `fpaste pki revoke <serial>` - Revoke certificate
|
|
- Config file for server URL and cert fingerprint
|
|
- Downloadable via `curl https://server/client > fpaste`
|
|
|
|
## Non-Goals (Explicit)
|
|
|
|
These features will not be implemented:
|
|
|
|
- **Web UI** - Out of scope; use API directly
|
|
- **User accounts** - PKI handles identity
|
|
- **Syntax highlighting** - Client responsibility
|
|
- **Search/discovery** - Pastes are private by design
|
|
- **Clustering** - Scale via container orchestration
|
|
- **S3/PostgreSQL backend** - SQLite is sufficient
|
|
|
|

|
|
| 2024-12 | CI/CD with job dependencies | Tests wait for lint to pass

|
## Review Schedule
|
|
|
|
- **Monthly**: Review TODO.md, refine TASKLIST.md
|
|
- **Quarterly**: Evaluate roadmap phases, adjust priorities
|
|
- **Yearly**: Major version planning, scope review
