Limits worth knowing

  • A fingerprint proves file identity to you — not a public timestamping authority.
  • Password-protected files must be unlocked first if the tool cannot read them.

Frequently asked questions

  • Why fingerprint a PDF?
    To record that a specific output matches what you produced after redaction or cleaning.
  • Does fingerprinting upload my file?
    No. Hashing runs locally.
  • Is this the same as a privacy receipt?
    Related — several privacy tools can download a receipt that includes hashes. Fingerprint is the focused tool.
