The birth of Simplexity

Today I officially announce and present Simplexity and set it free into the world.

Well, not "free" free.

Hereafter this shall be known as Grey Wednesday.

Sci.Crypt

If you can wade through the worthless noise, there is some good discussion and information on the sci.crypt Google Group about Simplexity.

Online Data Viewer

I have created a generic Online Data Viewer utility that displays "binary" data from an uploaded file in a visual format. (it will work on any data, including plain text ASCII files, since all data is basically binary)

It is an 8-Bit / Byte Data Visualizer Chart-Grapher utility.

This can be an interesting way to visually view and analyze data.
It's particularly useful in showing patterns, as well as seeming randomness, the latter being more difficult to be sure about. Patterns tend to be very evident.

Bug in example encryptor

On our about June 24 a bug (or two) was found in the example encryption implementation program.

If an attempt was made to encrypt a small dataset less than 28 bytes, an infinite loop occurred.
There was also an instance where a seed-modified could reach zero and not change after that.

The old version is here:

sci.crypt and other groups

Since the conversation at sci.crypt (and too many groups) falls somewhere between questionable and useless, except for the very few people who are interested in contributing worthwhile commentary to the discussion, I will only discuss Simplexity here now. If people are interested in it, they can make comments and ask questions here, hopefully without all the useless noise.

(I have instituted an artificial intelligence program here that prevents asinine, overly and unduly negative, and derogatory comments (and the like) -- I should probably patent that algorithm)

Contrary to what some people arbitrarily (and erroneously) claim and suggest, Simplexity has not come close to being proved unsecure, breakable and crackable (using an 'elegant' attack -- afaik, it is absolutely unbreakable/uncrackable using a brute force attack), etc. Its status still remains to be seen.

Compiled BASIC executable example implementation

A QB64 compiled BASIC example program that emulates the online example program is now available.
It should run on most Windows computers. It uses a simple "DOS" text interface.
It is a self-contained executable, so it is ~2.3MB in size.

You have to use right-click "Save As..." (or whatever your browser uses) to download the file(s).
The source code is available, as well as a syntax highlighted version.
And an archive ZIP file of all three files is also available.

simplexitycypherexample.exe
simplexitycypherexample.bas
simplexitycypher_poc_examp_impl_synhi_qb64.php

simplexitycypherexample_dos.zip

The executable allows file sizes up to 500K. (online is limited to 100K)
Installation is as simple as saving the executable program file into a directory somewhere and
double-clicking on it to run. (afaik, no installation program is necessary)

Let me know if you find any problems.

A Visual Basic 6 Windows GUI version will be available soon.
