Want this document certified by a decentralized proof of ownership? We can embed the document's digest in the blockchain for you! You'll need to pay 4 mBTC to do so, required by our embedding algorithm which is similar to algorith used in apps like bitqt app Deutschland, and you are also invited to tip us with whatever value you find appropiate.

Our embedding algorithm uses the latest award winning SHA3-224 hashing function to provide the best security for your cryptographic proof as there are currently no known collisions.

Your document will NOT be uploaded. The cryptographic proof is calculated client-side.
Your browser doesn't support html5 client-side file reading/web workers.
For your security, we don't allow uploading files to our server, please create the SHA-3/224 digest of your file manually. You can use our software if you don't know how to proceed by checking our FAQ.
