// thought cipher — shared key, local reveal
The keeper writes thoughts as envelopes — scrambled blocks that mean nothing on their own. One symmetric key opens all of them. This page hands you that key, but only if you already know the keeper the way a friend would.
One line from the bio. Fill the blank:
“100% of the path is ______.”
This is a shared decoder key, not a public key. It is one symmetric secret. Whoever holds it can decode every thought-cipher envelope — past and future — made with it. Keep it and use it whenever you like; but anyone you hand it to gets that same access to all of those thoughts.
Reveal the key above first. Then paste an envelope to open it right here. You can also copy the key into the local/Tailscale decoder, or any compatible thought-cipher decoder, and open envelopes there instead — now or any time later.
Everything happens in your browser. Your answer, the revealed key, any envelope you paste, and the decoded thought never leave this page — there is no server call, no upload, and no analytics or third-party script. Read the source if you like; the page carries only a passphrase-wrapped capsule, never the plain key.
