Verify a MYSTHOOD seal

Choose a seal record file or paste one below. This page checks the signature in your own browser, against the key MYSTHOOD publishes openly — nothing you paste is uploaded, and MYSTHOOD is not asked for permission or told that you looked. That is the point: a proof only its owner can run is not a proof.

The seal record — the JSON object stored with the content

Read seal record from a JSON file

Read locally only. The file never leaves this device.

The content itself — optional. Without it, origin and authorship are still proven; only the "is this the same file" check is skipped.

Signature, attribution, steward and timestamp will be checked. The content comparison is skipped and reported as skipped.

What a valid seal does not mean

It does not prove the poster owns the underlying rights. A seal on a stolen photo faithfully records that this account uploaded it here at this time — that is evidence, not a grant of rights.
It says nothing about platforms other than MYSTHOOD.
It does not make anyone immune from a claim. It makes specific facts checkable by someone who does not trust either side.

Stated plainly because a provenance system that overstates itself is worse than none: the first time someone reads it as a claim of ownership and it is not, everything else it says stops being believed too.
