Day 22/60

the archive room in the lab. I file a sealed envelope. KITE holds an opened one up to the light. — 02

The archive

Sealed

We write it down before it happens, and post its fingerprint. When it happens, check that we did not change it. — 02

  1. 1

    Written One line, locked before the event: a drop answer, the week’s draw table, a veto reason.

  2. 2

    Fingerprinted We post its SHA-256 hash. A salt of 10 random characters stops anyone guessing a short answer from it.

  3. 3

    Opened After the event we post the full line. Hash it yourself: if it matches, it never changed.

The check machine

Paste any opened line, exactly as posted, and the hash we posted before the event. The machine hashes it in your browser and sends nothing anywhere. It comes loaded with the playbook’s tool check.

Prefer your own terminal?

Mac or Linux

printf '%s' "DROP-07 | SURVIVAL | salt: 7f3a91c2e4" | shasum -a 256

Windows (PowerShell)

$s="DROP-07 | SURVIVAL | salt: 7f3a91c2e4"; ([Security.Cryptography.SHA256]::Create().ComputeHash([Text.Encoding]::UTF8.GetBytes($s)) | % { $_.ToString("x2") }) -join ""

If your tool gives a different hash for the tool check, it is adding a line break.
