Obviously this tool wont just solve your cipher for you, you … You can lock screen orientation, keep screen on, turn on vibrations and play a sound. The Autokey Cipher is a much more secure way of generating the keystream than the Vigenère Cipher, which is amazing since for over 200 years it was believed that the Vigenère was unbreakable. The Great Cipher was a nomenclator cipher that the Rossignols continued using for several generations in the service of the French crown. The Beaufort Cipher, created by Sir Francis Beaufort, is based on the Beaufort square which is essentially the same as a Vigenère's tabula recta but in reverse order starting with the letter Z in the first row, wjere the first row and the last column serve the same purpose. It shouldn't be confused with a special variant of the Vigenère cipher, named Variant Beaufort. | Keyed caesar cipher Keyed Vigenere (Quagmire IV).
