Frequently Asked Questions
What counts as a proof record?

Do you offer discounts for non-profits?

What does AuthProof actually prove?
AuthProof creates a SHA-256 integrity fingerprint of your content, maintains a chain-of-custody audit trail, and can apply an Ed25519 cryptographic signature. Together, these provide verifiable evidence of the content’s integrity, authenticity, and provenance.
