VeritaCrypt produces tamper-evident receipts for files, events, and records. Every receipt is signed, timestamped, and independently verifiable — including by people who don't trust us.
Modern cryptography has been solving this problem for decades. VeritaCrypt packages it so non-cryptographers can use it — and defend it — in a courtroom, an audit, or a disagreement.
Your file or event is hashed locally. VeritaCrypt signs the digest with its key, adds a timestamp, and returns a receipt you can store forever.
The receipt is included in a Merkle transparency log. Periodic checkpoints are published to independent channels so the log cannot be silently rewritten.
Hand anyone the receipt. They can check the signature, the inclusion proof, and a published checkpoint — offline, with open tools, without asking our permission.
# Notarize a file — local hash, signed receipt, Merkle inclusion. $ veritacrypt notarize ./contract-final.pdf digest sha256:9f2b54…c8f3d signed-at 2026-04-21T12:00:00Z receipt contract-final.pdf.vc-receipt.json OK included in log checkpoint #00042 # Verify later — no network required, no trust in us required. $ veritacrypt verify ./contract-final.pdf \ --receipt ./contract-final.pdf.vc-receipt.json \ --checkpoint ./checkpoint-00042.txt ✓ digest matches ✓ signature valid ✓ receipt included at leaf 18,204 ✓ checkpoint countersigned by 3 independent witnesses RESULT: intact, notarized 2026-04-21T12:00:00Z
Chain-of-custody for evidence, discovery-proof archives, signed document sets that survive a deposition.
Tamper-evident audit logs that satisfy SOX, HIPAA, GDPR-style accountability, and internal controls attestations.
Timestamped source material and drafts so provenance is answerable years later, in any jurisdiction.
