Create Document Proof

Upload your document to generate a cryptographic hash. Your document never leaves your browser.

How ProofDeed Works

1

Hash Generated Locally

Your document is processed entirely in your browser using SHA-256 cryptographic hashing

2

Blockchain Verification

Hash + timestamp will be sent for permanent blockchain recording when backend is live

3

Downloadable Proof

A proof report helps you verify document integrity and prove it hasn't changed

Your Privacy is Protected

  • • Documents are processed entirely in your browser
  • • No files are uploaded to any server
  • • Only the cryptographic hash is generated
  • • Your document never leaves your device

Understanding the Process

1. Local Processing

Your document is processed entirely in your browser using SHA-256 algorithm. The file never leaves your device.

2. Blockchain Recording

When backend is live, hash + timestamp will be sent for permanent blockchain verification on Polygon network.

3. Proof Report

Download your proof report with hash and verification instructions to prove document integrity.
