Your file never leaves this device. It is read and
fingerprinted in your browser; only the 64-character fingerprint is sent
to the registry. Watch the network tab if you'd like to confirm.
What is this?
ByteRegistry lets people prove a file is theirs, and that they made it first.
Checking one is free, needs no account, and the file you dropped never left
your device — only a fingerprint of it was compared.
