ROT Cipher

Rotate letters by a specified number of positions in the alphabet

ROT13: Each letter shifts 13 positions forward

CTF Tips for ROT Ciphers

  • • ROT13 is the most common - try it first
  • • ROT ciphers are symmetric: ROT13(ROT13(text)) = text
  • • Try all rotations if you're unsure of the shift value
  • • Look for readable English words in the output
  • • ROT preserves letter case and non-alphabetic characters
  • • Some CTFs combine ROT with other ciphers
  • • Check for ROT applied to numbers (ROT5 for digits 0-9)
