Hand Written Encryption.. [05-31-18 ]
I remember the days of the 5-1/4” floppy disk. I also remember the TRs-80 from Radio shack, the progression to the 1.4Meg, 3-1/2” disks, GWBasic, Fortran,Pascal, my first computer the 386SX (whoa).
I remember the good ole DOS days, the kool graphics you could produce with “Ansi.sys”,the config.sys, auto exec.bat and how you can tweak your machine to go to “High Mem”, breaking the 640K barrier.

   I also remember when windows 3.1 hit the market and how many times i installed it and removed it because its was such a resource hog.

   Those were the days of the “BBS” or bulletin boards.. namely “Wildcat”. The world was your oyster. If enough BBS systems were tied together you can reach across the state line to chat to an old friend. Then almost overnight, the usher in  of “AOL”, the netscape browser, sprynet, and the internet .

    Times have certainly changed. Those were simpler times. Now your Data is highly valued to everybody. Every search engine, every social media, everywhere you shop. Privacy is difficult to maintain.

     It baffles my mind how the younger generation divulge their personnel information so willingly, giving little regard to what they give away and who knows it.

     Maybe its a generational thing but I’ve always been mindful of “Big Brother” and what information can be collected on me, my finances and my family.

      It is also why i’ve had an interest in handwriting encryption. Its been around forever. its been said that Leonardo da Vinci often wrote encrypted to keep prying eyes from watching his progress.

      There is a certain comfort in being able to write a quick note to yourself such as a password or a combination and know that there is a certain element of protection from others.

       Through the years I’ve taken notice of different systems that have been around for some time. I’ve desired a system thats wasn’t difficult to learn and that could be written pretty fast wether in handwriting or via a PC. The two systems that stand out for me the most are the “Elian Script” and “PigPen”. They both have similarities in that it could be reproduced quickly in a “tic-tac-toe” fashion to refresh your memory, but because the script is more a sketch than a character it wouldn’t be beneficial when typing a note on the PC.

      So I decided to design my own system being loosely based on these two systems.


   The similarity to them is the pattern. You would just draw the “tic-tac-toe” pattern and start at the bottom left with the alphabet. As you finish the top right square you would start over on the bottom left.


       c | f | i
______________       [First set of 9 letters]
       b | e | h
______________
       a | d | g


       cl | fo | ir
______________       [add next set of 9 letters]
       bk | en | hq
______________ 
       aj | dm | gp


       clu | fox   | ir
______________       [Add the last 8 letters]
       bkt | enw | hqz
______________ 
       ajs | dmv | gpy


====================================
The positions in the squares are noted by a different set of letters that indicate which box you’re refering to..

like this..


       g | U |P
______________ 
       j | X |C
______________ 
       d | n |b

the letter “g” has a circular opening in the top left therefore its position is “top left” of the pattern. Similarly, the letter “d“ is circular on the bottom left.
The same can be said for “P” and “b”.
The small “j” is used like a bracket “]” to denote opening in the middle left and “C” the middle right.
“U” and “n” reflect the top and bottom openings.
“X” will denote center letters.

Since there are 3 positions in the “tic-tac-toe” patterns to represent all the alphabets, you’ll need to identify which set you’re looking for in those boxes.

so we’ll use a dot notation. the period “.” will be set 1.
The semicolon “;” will be set 2 and the colon “:” will be set 3 ..

so set 1 would look like this:
 
                 [U]
            .      .      .
[g]        c   | f |    i          [P]
     ————————————-
                  [X]
[j]         b   | e |   h         [C]
     ————————————-

[d]         a   | d |   g         [b]
      ———————————-
         
                    [n]

To spell “bag” it would look like this “j.d.b.” Remember the letters reflect position and the dot notion reflect which column in the set we’re referring to.

the second set would be:


                     [U]
             ;         ;         ;

[g]         L      |O|      R      [P]
     ————————————-
                      [X]
[j]          K      |N|      Q      [C]
     ————————————-

[d]          J      |M|      P       [b]
      ———————————-

                       [n]


“Roll” would be spelled like this “P;u;g;g;”

the third set would be:

                       [U]
             :          :          :

[g]         U       | X |             [P]
     ————————————-
                        [X]
[j]          T       | W |      Z     [C]
     ————————————-

[d]          S      |  V  |     Y      [b]
      ———————————-

                         [n]

As you see there is never a p colon “:” position since we’re out of letters..

Now lets put them all together:


                          |U|
             .  ; :      . ;  :      . ; :
|g|         c l u    | f o x |    i r      |P|
     ————————————————
                           |X|
|j|          b k t   | e n w |   h q z  |C|
     —————————————

|d|         a j s    | d m v |   g p y  |b|
                            |n|


See it? Its a column-row like configuration. The letters are the box positions and the dot-notation is which character in that box.


you’ll only use the far right 9 letters shown below when writing notes. The dot notation will tell you what letter you’re dealing with in those boxes.

  . ; :
  a,j,s    =       d
  b,k,t    =       j
  c,l,u    =       q
  d,m,v   =      n
  e,n,w    =      x
  f,o,x     =       u
  g,p,y    =       b
  h,q,z    =       c
  i,r        =       p

“Billy” would be “j.p.q;q;b:”

Regarding "Hand Written Encryption.. " :  Nice decryption program

I like it Craig. I remember the one you and I used which was through a picture decryption. We may need to think about setting up a common place to forward each other messages. Greg
