Answers to Questions
How to encrypt using Rot cipher?
Rot-N cipher is a simple character substitution based on a shift (or rotation) of an alphabet. E.g. one letter is replaced by another (always the same) that is located further in the alphabet.
This is the basis of the famous Caesar code and its many variants modifying the shift. The most popular variant is the ROT13 which has the advantage of being reversible with a 26 letter alphabet (the encryption or decryption operations are identical because 13 is half of 26).
| Plain Alphabet | ABCDEFGHIJKLMNOPQRSTUVWXYZ |
| Cipher Alphabet Shift/Rotation of 1 | BCDEFGHIJKLMNOPQRSTUVWXYZA |
| Cipher Alphabet Shift/Rotation of 2 | CDEFGHIJKLMNOPQRSTUVWXYZAB |
| ... | ... |
| Cipher Alphabet Shift/Rotation of 13 | NOPQRSTUVWXYZABCDEFGHIJKLM |
| ... | ... |
Example: The message ROTATION coded on the alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ with an offset of N=13, gives the encrypted message EBGNGVBA.
How to decrypt Rot cipher?
Deciphering is very similar (or sometimes identical) to encryption, with a shift of the alphabet in the other direction.
