Anchorproof
Create a signing envelope. Your document never leaves this device.
Anchorproof produces verifiable evidence and an audit trail, shaped like an advanced
electronic signature. It is not a qualified electronic signature and not a QTSP service.
The service proves that a specific document hash was signed by the holder of a specific
key at a time attested by named timestamp authorities. It does not establish the signer's
legal identity. No document bytes, signing keys, or personal information are stored.
Step 1: Drop or choose the document to sign
