Verified Documents

Certificates for the HIDEA outboard engines that Supratechnic distributes, each with a digital fingerprint recorded on a public blockchain, so you can check that a copy you hold is exactly the one we published, and whether it is still the current version.

  1. Published here. We publish each document on this page with its date and version.
  2. Fingerprint timestamped. The file’s fingerprint (not the file) is timestamped on a public blockchain through OpenTimestamps, a free public service.
  3. Check any copy. Choose a PDF below and your own device tells you whether it matches.

Received a HIDEA certificate from a dealer or someone else? Check it here before you rely on it.

Nothing is uploaded. Your browser reads the file and computes its fingerprint on your own device.

These certificates were issued by the Dutch Certification Institute (DCI) to the manufacturer, Hangzhou Hidea Power Machinery Co., Ltd., under the EU Recreational Craft Directive 2013/53/EU. Supratechnic publishes them as the exclusive distributor of HIDEA outboard engines in Malaysia and Singapore.

How this works

What is a fingerprint?

A fingerprint (SHA-256) is a short code calculated from every byte of a file. Change even one character and the fingerprint changes completely, so matching fingerprints mean identical files.

What does the public blockchain timestamp prove?

That a file with this exact fingerprint existed no later than the time of the public blockchain block shown. Nobody, including Supratechnic, can backdate or alter that record.

What does it not prove?

It does not vouch for what the document says, and it is not an endorsement by OpenTimestamps, by the public blockchain, or by any organisation named in a document. It only proves that this is the file Supratechnic published, unchanged, and when. The certificates themselves remain the responsibility of the bodies that issued them.

Why are some versions marked “Superseded”?

When a document is updated, the old file is removed from this site. Its fingerprint and proof stay listed so that an older copy can still be recognised as genuine but out of date.

How can I check without trusting this page?

Download the document and its .ots proof, then drop both onto opentimestamps.org. It checks the proof against the public blockchain independently of this website.
