What is a ROT13 cipher?
ROT13 ("rotate by 13 places") is a simple substitution cipher that replaces each letter with the 13th letter after it in the English alphabet. Because the English alphabet has 26 letters, applying ROT13 twice restores the original text.
What is the difference between ROT13, ROT5, and ROT47?
ROT13 rotates alphabetical characters (A-Z, a-z). ROT5 rotates numeric digits (0-9 by 5 positions). ROT47 rotates all standard ASCII printable characters (from ASCII 33 `!` to 126 `~` by 47 positions).
