User Guide
What can you do with AM PROOF?
A plain-English guide to sealing, verifying, comparing, and exporting important digital files.
The Big Idea
AM PROOF creates a cryptographic fingerprint of your document or digital file. If anyone later claims the file was changed, AM PROOF helps verify whether the submitted file still matches the original sealed record.
4 Steps. That's It.
STEP 01 — Upload Any File
PDF, Word, photo, video, audio, invoice, contract, receipt, or evidence file. Your file stays on your device during local verification.
PDF, Word, photo, video, audio, invoice, contract, receipt, or evidence file. Your file stays on your device during local verification.
STEP 02 — AM PROOF Seals It
A SHA-256 fingerprint is computed. If one character, one pixel, or one byte changes, the fingerprint changes.

STEP 03 — Get an AM PROOF CODE

STEP 04 — Export When Needed

What Is an AM PROOF CODE?
An AM PROOF CODE is a portable cryptographic receipt tied to the file's SHA-256 hash and verification record. It helps another person verify whether the file matches the sealed record.
Use Cases
Someone Claims You Changed a Contract
Problem: A counterparty says your contract version was edited later.
How AM PROOF Helps: AM PROOF helps verify whether the submitted contract still matches the sealed record hash.
Result: Strong cryptographic evidence that supports verification and helps reduce disputes.
