The answer to Cipherday #58

The full three-cipher chain from August 20, 2026, the public-domain quote it hid, and how each cipher worked. Today’s chain stays sealed until it becomes a past day.

The revealed quote

“Whatever you do, do it well.”— traditional proverb

A short charge to bring your whole hand to the smallest task.

The cipher chain

1. Stage 1 · Caesar · Shift of 9

   Ciphertext

   Nenah luxdm qjb j bruena urwrwp.

   Decodes to

   Every cloud has a silver lining.

   Every letter was slid 9 places down the alphabet; sliding it back the same amount restores the line.

2. Stage 2 · Substitution · Keyword “ZEPHYR”

   Ciphertext

   Qk oyy z ukngh cj z anzcj kr ozjh.

   Decodes to

   To see a world in a grain of sand.

   A keyword scrambled the alphabet into a fixed cipher alphabet, so each letter always stands for the same partner — letter frequency gives it away.

3. Stage 3 · Rail-fence · 4 rails

   Ciphertext

   We oehvrudd wlae oo i lty,t.

   Decodes to

   Whatever you do, do it well.

   The letters were written in a zig-zag across the rails, then read row by row; re-weaving the zig-zag recovers the order.
