Chakloon Papers is a digital service designed to prove the existence of a file at a specific point in time. Instead of uploading files to a server, the service calculates a SHA-256 hash locally within the user's browser. It then records that a file with that specific fingerprint existed no later than the moment of registration, issuing a certificate containing a QR code. The service is part of the Chakloon suite and is available in 28 languages.
Functionality
The platform operates on a principle where the file itself is never transmitted to the service. Users, who utilize a Chakloon Passport account, generate a local hash to create a record. Once registered, the service provides a public registry where entries can be verified without logging in. Verification is possible by using a specific identification number, the hash itself, or by dragging and dropping the file into the interface. These records are permanent and cannot be deleted. The service is also available to developers through the Chakloon platform API.
Organisation
Chakloon Papers is an integral component of the Chakloon suite, which includes related services such as Chakloon Legal and Chakloon Sign. The service was launched on the general Chakloon framework in October 2026. It is important to note that the service does not function as a qualified electronic timestamp under the eIDAS regulation. The platform supports a wide range of languages, including English, French, German, Russian, and many others, to facilitate international use.
