The answer to Cipherday #53

The full three-cipher chain from August 15, 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

“A friend to all is a friend to none.”— attributed to Aristotle

A classical caution that friendship spread too thin is no friendship.

The cipher chain

1. Stage 1 · Caesar · Shift of 13

   Ciphertext

   Orggre yngr guna arire.

   Decodes to

   Better late than never.

   Every letter was slid 13 places down the alphabet; sliding it back the same amount restores the line.

2. Stage 2 · Substitution · Keyword “GRANITE”

   Ciphertext

   G qscsab ck scji qgviq kcki.

   Decodes to

   A stitch in time saves nine.

   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

   Ao t afonf a rtordlsi ninliedee n.

   Decodes to

   A friend to all is a friend to none.

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