Tamper‑evident signatures and license lineage for LoRA / adapter files

LoRA‑Provenance loraprov

📚 Docs: https://keithtyser.github.io/lora-provenance

Tamper‑evident signatures and license lineage for any LoRA / adapter file.

---

Quick‑start

# install (after first PyPI release)
pip install loraprov

# generate a signing key
loraprov key generate alice

# sign an adapter
loraprov sign adapter.safetensors --parent-sha 6efa... --license MIT --key alice

# verify before deploying
loraprov verify adapter.safetensors

Tip → to protect Hugging Face pushes, enable the pre‑upload filter.
Need compliance docs? loraprov sbom adapter.safetensors exports a CycloneDX SBOM instantly.

Why use LoRA‑Provenance?

Problem	Benefit
Poisoned adapters	Signature mismatch blocks deployment
License ambiguity	License + parent SHA embedded at sign‑time
Compliance (EU AI Act, NIST AI RMF)	One‑line SBOM and full provenance chain
Reproducibility	Cite an immutable SHA‑256 instead of a URL

Roadmap

• WebAssembly verifier (browser demo)
• Hardware‑backed keys (YubiKey)
• Lineage visualizer (interactive graph)
