  • Example: Hello → Khoor (shift: 3)
• Vigenère Cipher - Polyalphabetic substitution
  • Example: Hello → Rijvs (key: "KEY")
• Hill Cipher - Matrix-based polygraphic substitution
  • Example: Hello → AXDDTC (key matrix: [[2,3],[1,4]])
• ADFGVX Cipher - WWI German military cipher
  • Example: Attack → VGVADADVGAGA (key: "KEY")
• ROT13 - Simple letter substitution
  • Example: Hello → Uryyb
• Playfair Cipher - Historical digraph substitution (1854)
  • Example: Hello → KGAA (key: "PLAYFAIR")
• ASCII85 - Compact PostScript encoding
  • Example: Hello → <~87cURDZ~>
