Verifying this receipt

The hash above was computed as:

sha256( coalesce(url, '<no-url>') || '\n' || raw_content )

Anyone with a copy of the original document can verify the match:

  1. Take the URL field and the original document content.
  2. Concatenate url + '\n' + content and SHA-256 it.
  3. Compare to the SHA-256 row above.

Or POST the candidate content to /source/5687/verify and our server will compare for you:

curl -X POST https://www.goblinhouse.net/source/5687/verify \
  -H "Content-Type: text/plain" \
