ProofBundle is a local-first tool for creating portable evidence dossiers for files, ZIP archives and complete directories. The original work remains on your device and does not need to be uploaded to Ilion or another verification service.

What it creates

A deterministic manifest of the selected files
Cryptographic hashes and a Merkle root
A signed Ed25519 or OpenPGP claim
An optional OpenTimestamps proof
A portable dossier designed for offline verification

How it works

Create the evidence bundle locally.
Store the original work, private key and evidence separately.
Share the dossier with a client, collaborator or archive.
Verify later that the files, manifest and signed claim have not changed.

Who it is for

Photographers, illustrators and designers
Writers, musicians and digital creators
Studios and creative agencies
Professionals delivering files to clients
Teams preserving approved project versions
Anyone who needs reproducible technical evidence for digital material

Clear limitations

ProofBundle can document existence, integrity, temporal priority and a signed claim associated with a work. It does not by itself prove originality, legal authorship or ownership. It does not replace copyright registration, public registries, contracts, official deposits, courts or legal advice.
