The Cipher Cross-off list is a place where cipher schemes are listed that have been identified. Where Vigenere adds the message to the key, Beaufort subtract the message to the key. It was named after Sir Francis Beaufort, an Irish officer in the Royal Navy. Note: Auto Solve will try in the mode you select (Standard Mode or Autokey mode). The plaintext letter is subtracted from the key letter instead of adding them. The Beaufort cipher is reciprocal, that is, decryption and encryption algorithms are the same. It is closely related to the Vigenere cipher, but uses a different method of generating the key. Depending on input plain text block size, number of rounds and key size, various instances of RC5 can be defined and each instance is denoted as RC5-w/r/b where w=word size in bits, r=number of rounds and b=key size in bytes.
