Drop a certificate in. This page checks it and tells you one of three things. It is a single file:
no server, no runtime download, no network request of any kind — disconnect and it still
works.
Drop a file here, or — one file, nothing else to set up.
no document yet
Three answers, and the third is not a polite second
ACCEPT
this verifier checked the document and it holds
REJECT
this verifier checked the document and it does not hold
REFUSE
this verifier did not check it, and the reason code says why. It is not a
statement about the document: another project's valid certificate lands here, and so does a
certificate naming a specification this page does not carry.
A Farkas certificate names the specification it was issued against by fingerprint. This
page carries 7 published specifications and checks a certificate against
the one it names — never against something convenient. An unknown fingerprint is refused; a
fingerprint swapped for another specification this page does hold is rejected.
Optional: the outcome trace
Only needed to re-derive a decoder-audit certificate's Merkle root. Without it the root
is reported as not checked, never as passing.
