Can you crack codes with Mathcad?

[DanMarotta]

Hello Mathcad Members,

I was reading an article today on the U.S. Cyber Command. They created a logo that contains a 32-character secret code in it's inner circle. No one has yet been able to crack it.

It made me think of the Mathcad members here. They have some of the brightest minds around. Have you used Mathcad to crack codes? I'd love to hear your stories or see examples (law abiding of course ). Feel free to reply to this thread or start your own discussion in the Puzzles and Games sub-community.

Texas Instruments had very good tutorial in "coding" [1980 or around].

Attached, the work sheet from Susan Diesel [Mathsoft].

The 32 characters my be a coded image, a pixel image of a name,

a name in short or recognizable as a piece of priviledged information.

Let your imagination go.

Have you ever imagined that any avatar in this community can

embed a coding ? ... the coding embedded back to the originator !

That code could just be not coded at all or so simply like the coordinates

of an electronic signature, an electronic signature not dogitized but

from a user spline creation..

Here's the article if you wanted to take a crack at decoding the logo

[jeanGiraud]

I have summed the components of the source code,

made a graph of all the leading digits + the sum

source code [50 digits], you can increase the size

by adding trailing digits.

Any Mthcad volunteer to retrieve a 5 digits code ?

Example: from shuffled 5 digits, retrieve 93758 ?

If the 50 digits code is shuffle by the panic button ...

Could Mathcad recover ?

If it could theoretically, by implementing a "big number"

engine for such a long number as 50 digits ...

??? how many years ???

Comments:

1. I won't give the source generator of the 50 digits number,

simply too naive for somebody handling minimal maths.

2. the panic button could shuffle all the 50 digits or a chunk,

the retrieving process would complicate and simplify.

jmG is done and gone on that one

... the above graph embeds the 50 digit code ,

a peanut job to retrive this number !

If the components of the "cyber" code would be

shuffled ... a bigger peanut job to retrieve.

Amazing that what's man made can be man undone.

That reminds my room mate in the Air Forces, he

unlocked any tumble padlock [they were not

made in China !]
