Caesar-Chiffre

Die Caesar-Chiffre ist auch bekannt als "ROT" (z.B. "ROT-13"). Wobei das absolut nichts mit der Farbe zu tun hat (Caesar ist nicht 13 mal beim Anblick von Cleopatra errötet – er benutzte diese "Verschlüsselung" lediglich für seine militärische Korrespondenz), sondern vielmehr mit dem Rotieren der Buchstaben um X (Rot-13: 13) Positionen.

Morse Code

Morsecode wurde früher in der Telegrafie verwendet – ist aber auch noch heute in der Seefahrt gebräuchlich (oft mit Lichtzeichen): Am bekanntesten ist hier sicherlich das SOS Signal.
