WebThe Beaufort Cipher is named after Sir Francis Beaufort. It is similar to the Vigenère cipher, but uses a different "tabula recta". The plaintext letter is subtracted from the key letter instead of adding them. The Beaufort Cipher is reciprocal (the encryption and decryption algorithms are the same). Beaufort Cipher Tool WebRot-N/Rot cipher (for Rotation) is a simple character substitution based on a shift/rotation of N letters in an alphabet. E.g. one letter is replaced by another (always the same) that is located further (exactly N letters further) in the alphabet. This is the basis of the famous Caesar code and its many variants modifying the shift.
