Karsten Siebert, Scharfenberger Strasse 40a, D-01139 Dresden, Germany. This site signs digital documents using cryptographic information. It can be used to confirm the authenticity of digital documents.

This site does not use cookies and does not collect any information about users who use this service. The site calculates cryptographic values based on a provided document and stores the resulting fingerprint on the Cardano blockchain. Files for signing are only stored temporarily for cryptographic calculations. After finishing the calculation, files are immediately, automatically removed from memory. By using this service, you agree that your file to be signed may be stored in memory for the duration of necessary cryptographic calculations.

Files can be verified on verify-file.com. If the fingerprint matches, the authenticity of the provided file is confirmed. If the issuer of the document agreed to publish his information, this information is displayed with the result of the calculation and the found information. All information is provided "as is".

Signing files without storing the fingerprint on the blockchain is free of charge, but requires an accout at tokenizer.biz. Storing the fingerprint on the blockchain requires sufficient ADA in the user wallet to process one transaction.
