How to Create Easy and Tough to Break Substitution Codes

Step-by-Step Guide

1. 1

   Step 1: Easy- and Tough-to-Break Substitution Codes: AUGUSTUS'S CODE

   A became B, B became C, and so on right to the end of the line where Z became A. ,,,, Let's say you use 31 as your key number.
   
   This means the first letter of your secret message is written three letters higher in the alphabet.
   
   The second letter of your message is written one letter higher in the alphabet. ,, Let's say it's death.
   
   Write it down, then follow it with the letters of the alphabet that are not in the key word. ,,,,,,,,,,,, Since AB is above it and KLM to the far right of it, using one letter form each group, A can become:
   AK, AL, AM, KA, LA, MA, BK, BL, BM, KB, LB, or MB.
   
   Take your choice!The letter O(as well as the other letters in the vertical column at the far right) has even more possibilities, since it has IJZ above it, and QRS to the right of it.
   
   It can be changed into eighteen two-letter combinations:
   IQ, IR, IS, RI, SI, JQ, JR, JS, QJ, RJ, SJ, ZQ, ZR, ZS, QZ, RZ, or SZ.In the Crisscross code, Meet me at noon, could be coded in more ways than any of us would like to count.
   
   But here's one way:
   Erilmjuj fsjl lbvi shjrqiqg. ,,,,,, Remember, the far left column, then the top row.
   
   Like before, there are many combinations.
   
   One combination for:
   I think you're swell, would be:
   BAA, CCC, ACA, BAA, CCA, BBC, CAB, CAA, AAC, CBB, CBC, AAC, BCC, BCC. ,,,,,,,,,,,, The key-word C, beneath it, equals
   13.
   
   When you add the two together they came up with the number 27-the first number of the coded message.In the Nihilist Number code, Down with the Czar, would be: 27 45 96 46 63 68 ,,,,,,,,, First you found the letter H on your checkerboard.
   
   To the left of it was the number
   2.
   
   Above it was the number
   3.
   
   So you tapped twice, paused, and tapped three times.
   
   That zeroed your friend in on the letter H-located in the second horizontal row and the third vertical row.
   
   Continue this process to form words by tapping letter combinations.
   
   In the Prisoner's code, HELLO, would be: 2 taps, pause, 3 taps, pause, 1 tap, pause, 5 taps, pause, 3 taps, pause, 1 tap, pause, 3 taps, pause, 1 tap, pause, 3 taps, pause, and 4 taps ,,,,, That's all.

5. 5

   Step 5: BACON'S ABC CODE

6. 6

   Step 6: and THE NIHILIST NUMBER CODE.

7. 7

   Step 7: AUGUSTUS'S CODE: just substitute the next letter of the alphabet for the original one.

8. 8

   Step 8: ABCDEFGHIJKLMNOPQRSTUVWXYZ

    Step 14: In the Key-Number code

15. 15

    Step 15: Attack at dawn

16. 16

    Step 16: would be: Duwbfl du gbzo(using 31 as your key-number).

17. 17

    Step 17: KEY-WORD CODE: think of a word of five or more letters in which no letter is used more than once.

18. 18

    Step 18: DEATHBCFGIJKL

19. 19

    Step 19: MNOPQRSUVWXYZ

20. 20

    Step 20: Just use the letter above or below the actual letter in your message.

21. 21

    Step 21: In the Key-Word code

22. 22

    Step 22: Meet me after school

23. 23

    Step 23: would be: Dnnp dn nupnb csqaaz

24. 24

    Step 24: CRISSCROSS CODE: a letter can be substituted for a great number of letters.

25. 25

    Step 25: AB CD EF GH IJZ

31. 31

    Step 31: The letter A can be changed into any one of a dozen two-letter combinations.

32. 32

    Step 32: BACON'S ABC CODE:

37. 37

    Step 37: In Bacon's ABC code

38. 38

    Step 38: I think you're swell

39. 39

48. 48

    Step 48: In the message

49. 49

    Step 49: Down with the Czar

50. 50

    Step 50: it would be written out this way with the key word repeated underneath it:

51. 51

52. 52

    Step 52: Key word:CATC ATCA TCA TCAT

53. 53

67. 67

    Step 67:  The English letter y is the number zero in Saurian.

68. 68

    Step 68:  Proper nouns should remain unchanged when converting.

69. 69

    Step 69: Now proper names can be changed but put \ / around them then convert so people know it's a proper noun
