  1. Famous Unsolved Codes & Ciphers

  2. Four popular cipher texts - Dorabella Cipher - Voynich Manuscript - D’Agapeyeff cipher - Beale Ciphers

  3. Features Encrypted letter written and edited by Edward Elgar (Romantic composer) to Miss Dora Penny in 1897 She was never able to decrypt 87 characters 3 lines Alphabet of 24 symbols 1,2,3 approximate semicircles. 8 directions Small dot: significance unknown simple substitution cipher: fruitless Expected to be much more complex. Dorabella Cipher

  4. This cipher has a very interesting shape, and as mentioned before, consists of semicircles and dots; does not fit pattern of simple substitution. Can YOU figure it out??

  5. Voynich manuscript Features Book named after Wilfrid M Voynich who acquired in 1912 Written between 1450 – 1520 Unknown author Unidentified script Intensely studied by American and British code breakers of World War II, but all failed to decode even a single word. This string of failures made it famous Elaborate hoax? Meaningless arbitrary symbols.

  6. Here is a bit closer look at this special cipher…

  7. D’Agapeyeff Cipher Features Written by Russian born English cartographer Alexander D'Agapeyeff Available in First edition of his Codes and Ciphers published in 1939. Offered as “challenge cipher” at the end of book. Not included in later editions.

  8. Numbers have actually played a large part in codes, computers, and hidden messages. And you thought they were just math!!!

  9. Beale Ciphers

  10. First letter

  11. Second letter

  12. Third letter

  13. Features Beale ciphers are a set of 3 cipher texts Letter 1: Location Letter 2: Worth Letter 3: Next of Kin 2nd letter deciphered using US Declaration of independence book as it’s key.

  15. As you can see, codes, ciphers, and messages are just another puzzle that needs to be solved… Mathematicians everywhere push their brains to the limit to try to solve these enigmas… Will you be the next great codebreaker??
