Partisan for investigations and asset recovery

Receipts for the documents you gather and exchange

Bank records, invoices and corporate filings move between parties and jurisdictions. Partisan gives each file a dated receipt, so any later change shows up as a mismatch.

Your document is never seen or stored. Partisan records only its fingerprint.

Where it helpsTypical uses

Gathered records

Record documents as they come in.

Cross-border exchange

Share the receipt with the other side so both can check the same file.

Recovery proceedings

Show a file is unchanged since it was recorded.

Partisan records a file's fingerprint without seeing or keeping the document, gives a dated receipt, and shows a file is unchanged since it was recorded.

Plain limitsWhat it shows, and what it does not

It shows

A file is unchanged since it was recorded.
The date and time the fingerprint was recorded.

It does not show

That the contents are true.
Who wrote the file.
When the file was first created.

Independent checkCheck it yourself, without us

You can get the same fingerprint yourself in CyberChef, so you are not relying only on Partisan.

CyberChef is a free, open source tool that runs in your web browser.

Open CyberChef in your browser.
Drop in your file and choose the fingerprint method named on your receipt.
Compare the result with the fingerprint on your receipt. If they match, the file is unchanged since it was recorded.
