The answer to Cipherday #71

The full three-cipher chain from September 2, 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

“Absence makes the heart grow fonder.”— traditional proverb

Distance can sharpen how much a person is missed.

The cipher chain

  1. Stage 1 · Caesar · Shift of 24

    Ciphertext

    Jmqr rgkc gq lctcp dmslb yeygl.

    Decodes to

    Lost time is never found again.

    Every letter was slid 24 places down the alphabet; sliding it back the same amount restores the line.

  2. Stage 2 · Substitution · Keyword “GALLEON”

    Ciphertext

    Em kmt lry mvor spdit jdih.

    Decodes to

    Do not cry over spilt milk.

    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 · Vigenère · Keyword “CIPHER”

    Ciphertext

    Cjhlrtg uprij vpt oirtb vysn hwckii.

    Decodes to

    Absence makes the heart grow fonder.

    A repeating keyword shifted each letter by a different amount, which is what lets one letter encrypt two ways; the right keyword resolves it.
