Record a file. Add publication evidence. Verify a record.
Electronic Registry creates a public record for the exact SHA-256 hash of a file and can later attach a public reference to that same file as publication evidence. It does not prove ownership, authorship, truth, legality, or official approval.
Paste the SHA-256 hash or choose the file to check whether the exact same file has a registry record.
A clear procedure, not a set of disconnected tools
Start with the exact file. Add publication evidence only when you want to attach a public reference. Later, verify the same file or its SHA-256 hash to confirm whether a record exists.
Record a file
Create the first public record for the exact SHA-256 hash of the file.
Add publication evidence
Attach a public reference to a file that is already recorded when you need that extra evidence.
Verify a record
Later, verify the same file or its SHA-256 hash to confirm whether a record exists.
What the registry proves — and what it does not prove
Electronic Registry records technical facts about declared records and their timing. It does not act as a judge, publisher, or legal authority.
A declaration was written for the exact SHA-256 hash of a file.
Ownership, authorship, originality, truth, legality, or official approval.
When the record was written to the registry.
That a public reference is the original or only source.
Whether the same file matches when the original file or exact hash is available.
The file itself without the original file or exact hash.
