Module 22 · Sealed proof

The sealed report

Sometimes it is not enough to know: you have to prove. Beyond the monthly statement, Ozorys can produce a sealed, tamper-proof document that attests to your finances without revealing anything to anyone.

Your statement receives a SHA-256 seal: the slightest change becomes detectable.

A cryptographic seal

The sealed report (Ultra plan) is a document struck with a cryptographic seal: a SHA-256 fingerprint that makes it tamper-proof. The slightest alteration is detected. It is the ideal proof to attest to income, file an exhibit in a dispute, or hand over a statement whose authenticity is beyond question.

Key point

The SHA-256 fingerprint is a unique signature of the content: change a comma, and the fingerprint changes. A sealed report is therefore a document you can prove has not been retouched.

The report on demand

You choose the period — a month, a quarter, a year — and Ozorys produces a genuinely elegant PDF: logo, summary, detailed operations, stamp and fingerprint. You can generate either this refined statement to present, or a sealed verification file, meant to prove integrity.

Everything is generated locally, on your device, from your decrypted vault. No data leaves anywhere to build the document.

The key on paper, the ultimate net

Sovereignty is also protected offline. The paper QR backup prints your recovery key as a code, to be tucked away in a drawer or a safe — cold storage in the literal sense. Combined with an encrypted backup, it puts you permanently out of reach of loss.

Module challenge

Put the proof to the test

Generate a report for your month and look at the stamp and fingerprint at the foot of the document. Imagine having to prove your income to a landlord: you hold a clean, dated document whose authenticity can be verified. That is sovereign proof.
