Authenticator sheet
Generates a full twelve-month authenticator list — an AUTHENTICATE and a VERIFICATION word pair for every day of every month — laid out as a two-sided fold sheet ready to print. Everything is derived from the seed with PBKDF2 and HMAC-SHA-256, so the same seed and year always reproduce the identical sheet on any machine, while nobody without the seed can predict any of it.
Edition ID printed in the header.
This is the key. Anyone holding it reproduces this exact sheet; nobody without it can predict a single pair. Prefer Random seed over a phrase you thought up, and protect it like the sheet itself.
