## Description

Tamper-proof auditable evidence for your documents.

Tamper-proof auditable evidence for your documents.

Choose a file, and HashDoc creates a cryptographic hash on your device, seals that hash on the blockchain, and generates a proof you can store, share, and verify later. Your original files stay on your device and private at all times.

Use HashDoc to:

Create proof for documents, deeds, audits, code, photos, and video
Generate a shareable proof PDF
Verify whether a file still matches its original seal
Add optional account-backed attribution
Keep control of your files with local-first handling and full privacy
HashDoc is built for auditors, creators, IP professionals, compliance teams and individuals who need a clear integrity trail for the files that matter most.
