The answer to Cipherday #72

The full three-cipher chain from September 3, 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

“Do not count your chickens before they hatch.”— traditional proverb

Wait for the thing to arrive before you tally its rewards.

The cipher chain

1. Stage 1 · Caesar · Shift of 3

   Ciphertext

   Xqlwhg zh vwdqg, glylghg zh idoo.

   Decodes to

   United we stand, divided we fall.

   Every letter was slid 3 places down the alphabet; sliding it back the same amount restores the line.

2. Stage 2 · Substitution · Keyword “PARABLE”

   Ciphertext

   P wptrdlb nmt klvlq amfis.

   Decodes to

   A watched pot never boils.

   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 · 6 rails

   Ciphertext

   Dnioaouthcfrht o ckee cncy eb yho orn te.tush

   Decodes to

   Do not count your chickens before they hatch.

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