Hey, I'm looking for a new project to do, any ideas? I just finished (testing now) my AES code, in the 'main' section of forum, and I need something to do... Here were my ideas, could someone please give me more?

1) Other algo's, like a fast RC6 or something as large as RSA.

2) A .asm file compressor, I was going to start researching on that, here is what it would actually do:

- Uses 8-bit as it's internal language, gives 255 dictionary possibilities and one escape code

- Layer 1 compresses common instructions like mov/add, statistics gained from a collection of hte largest FASM projects I could get my hands on

- Layer 2 compresses common english words like 'the', 'of', among many others. Statistics also gained the same way.

- Layer 3 compresses common english letters, maybe even the whole ASCII possibilities. (they wouldn't really be compressed due to the 8-bit internal size, but the 8-bit escape code followed by an 8-bit character was just too much)

As you can see, I was leaning towards my second idea for something to work on. Does anyone need help on anything at all? Or maybe you would like something done? (Please say it's another crypto algo!)

For now I'll go back to reading my RSA book... I did many little factoring and fun stuff, one day I hope to have an RSA code running Smile. Either that or a fast GNFS system that will run on multiple Win32 computers! Yeah, so any help or projects needed?!

Have you seen the RSA macros?

I am not interested in the pre-processing code, I have had those for a while now, and love the way you did it Smile. My idea is for learning RSA, not as much as making a good implementation. I will study it (RSA and NT books, ect.) until I feel I am ready to start trying out primality techniques, powmod, mul, and others...

There are so many ways of approaching the cipher, so many trade-offs between code size, speed, specific processor optimizations, and soo many different algorithms to get the job done.. I will study it for as long as I can hold back and then I will jump in (starting with the most basic, slow method I can code, you know which one Smile.)

Unless someone else has a project they need help with, I'm going back to my math. I lost so much sleep over the AES code (the workings I posted were such a small fraction of the different implementations I made), my math teacher (idol of my life almost) has disliked my seemingly lazy-ass state of mind (actually, on the contrary of lazy...). I'll take a few months off and get back into math... It's amazing how hard it is to switch between real and abstract Smile. All for now, I'll make myself a little lesson plan for this project like always.

The main problem is that RSA and RC6 algorithm are so hard to debug that they are impossible to achieve in assembler with THE STEPS : compiling/running debugger , compiling/running debugger , compiling/running debugger , compiling/running debugger

what you need is an interpretor for RSA & RC6 algorithm.

The main problem is that if you use a USUAL INTERPRETED language, you are not programming in assembler and this is wierd...

that's why I am working programming an ASM INTERPRETOR. it is only 16BIT nowadays, but I keep trying to inprove it... thank you for your patience!

Well, thanks for suggestions, but I will go along with RSA in x86. (would it be considered x87 because of SSE?). I usually need to learn what to do through experience, I always have crazy ideas that flop in the end Smile.

Thanks, and I will definitely look into interpreted Confused...

BTW: I've seen RSA in Java, it's TINYYYY and soo slowwww.... I love how simple it is though Smile. Here it is:

[edit] WHat do you think about what this guy said here:

For example, you could time the gap between key strokes, in microseconds, and then take the lowest bit of this number. Techniques like this are random enough for cryptographic purposes.

Math? Very Happy I like to code solutions to http://projecteuler.net/ problems in x86 - it's great fun if you like math.

Smile #182 is RSA

I've seen those, I do love math, but I would like to do something a little more constuctive. I already have a nice little folder with a bunch of those in it...

[edit]: lol! "Quantum" performed more than a double-post in a nearby thread, he did a 9-post! Just a little thing I saw, that's funny

Have you seen this compression?

Smile Thanks bitRAKE, if I do choose to do compression (I found a very nice site that lookes like that, here it is below:), I will definitely look at those sources. I have never done parsing before, but I think I'll stay on the crypto path at least a little longer.

That link seems like a good intro to compression - the Apply IIgs was an awesome machine at the time (although I only programmed in BASIC and Logo on it).

Wiki explains much of PAQ.

Thanks, interesting that there are awards for compression

The most important question (maybe the only question) of information theory is how much information is present in a communication, and compression tries to provide an actual answer (verses theoretical answers: entropy).

I've been reading some articles about the AI side of compression, that's some interesting stuff... I'm almost thinking about considering compresssion as my next project Smile

This ain't compression or anything ... but about Fractals. Lots and lots and LOTS of repetitions, suitable for fasm.

The software is apophysis. New version of it is called flam3

It's open-source

The other day I was playing with it the renderer ate up all the 4GB of my RAM and crashed my system.

So I was going to look into the code, trying to find the thing that ate up humongous amount of RAM, and in the meantime, perhaps speed up the thing a bit with fasm.

Perhaps you may want to take a look into this ... for I don't have a lot of free time myself.

Just a suggestion.....

At the forum there is a GPU accelerated version - which is perfect for this type of thing. Thanks for the eye candy - really cool stuff.

That GPU accelerated version is called flam4, yep, it ought to be exciting !

Unfortunately, I don't have Vista, so can't even test it out. Sad

Oh yes, before I forget, they do have a "paper" describing all the aspects of Apophysis, flam3 and flam4.

The document is in pdf, it's 22.5MB in size. It's available from http://flam3.com/flame_draves.pdf

Hope this helps !!

As you wish .... squeezing from 22.5mb to a little less than 6mb, while still preserving the vibrant colors of the embedded photos.

Get it at www.PenangA1.com/flam/flam3.pdf

I know 6mb is still quite large, unless someone can come up with a much better pdf compressor. :)
