We use the SHA 256 algorithm to compute a hash of your files. This is done in your browser so the contents of your files remain confidential.
We store the SHA 256 hash of your email, the SHA 256 hash of your file and a timestamp on the Ethereum blockchain. The timestamp is generated by the blockchain, so there is no chance of tampering.
Once the blockchain confirms storage of your record, we notify you by email. This typically takes a few minutes.
