## Answer

Generate a local fingerprint of your PDF for your own records or privacy receipts. Processing stays in the browser — useful before and after Confidential Send.

## Limits

- 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.

## FAQ

### 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.
