Standard digital evidence is vulnerable to the "Liar's Dividend" and deepfake fraud. The VRA Desktop Auditor is a free, zero-trust, air-gapped tool that lets anyone independently confirm a Truth Packet's cryptographic integrity — that its bytes still match the hash sealed at capture time.
The Mechanics
The cryptographic baseline checks — hash match, manifest chain, embedded EXIF and C2PA — run locally on the bytes on disk, without uploading sensitive evidence to a third-party server. Optional online cross-checks (Arweave permaweb, Command Centre) are opt-in and used only to confirm public anchors.
Checks software origin, hardware integrity, multi-clock temporal timestamps, and chain-of-custody continuity against the sealed record.
Independently recomputes the 64-character SHA-256 signature of the sealed file and confirms it still matches the hash recorded at capture time — a tamper-evidence check, not proof of what the footage depicts.

CLEARANCE: PUBLICA handyman sealed a cable repair while the ladder was still up. Download that Truth Packet and drop it into the Auditor. The Auditor calculates the hash of the file and checks whether that hash is in our database. A match means the bytes still match the capture.
