The answer to Cipherday #78

The full three-cipher chain from September 9, 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

“To finish first you must first finish.”— traditional racing adage

A reminder that completion comes before any medal.

The cipher chain

1. Stage 1 · Caesar · Shift of 16

   Ciphertext

   Dej qbb jxeiu mxe mqdtuh qhu beij.

   Decodes to

   Not all those who wander are lost.

   Every letter was slid 16 places down the alphabet; sliding it back the same amount restores the line.

2. Stage 2 · Substitution · Keyword “BEACON”

   Ciphertext

   Tfo ebkemm tfbt eolcs gs strmldor tfbl tfo mbi tfbt rosgsts.

   Decodes to

   The bamboo that bends is stronger than the oak that resists.

   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 · 5 rails

   Ciphertext

   Thy ios otffn iftusi ifnis urts.irmsh

   Decodes to

   To finish first you must first finish.

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