Numeric Ciphers Explained: The method for the example messages



Keywords and Plain Message are coverted to numeric form by chart;

where a=11, z=36, 0 (zero) =00,9=09, 10=10. Math for these messages is

transfby addition and subtraction



The keys are encrypted letter by letter by adding a number from 0—9. Those numbers are a Key Encrypting Key (KEK). In this case 4 2 0 8 6 5 3 1 8 7.

They use the same additive for both messages. No other keywords were used, meaning

no cello, bass, violin, viola, drum, tympani, cymbal, harp, piano.

Trombone becomes 3430253118302716. Trumpet becomes 39353525262336

Piccolo becomes 31221422322627 Clarinet is 1623203723261538





“Cough” is the first padded word for both messages.
