CycleByte


This is an encryption I've come up with, basically it randomly scrabbles the bytes of data in a file or whatever in such a way to defeat packet sniffing.

I haven't had a chance to test it yet but it compiles and I cant think of a reason it should fail form reading the code. I'll continue work at a latter date.

The hell  :huh:

How can I actually test it? Should I use the dll?

To use this you have to import the header files and the lib file into your C++ project. Then make sure the actual DLL is included with your application.

holly crap really?
if you do I will... do something

I need to expand the capabilities of this lib to use IO streams...

How about hltypes instead? :naughty: I promise, hltypes::AnyStreamRelatedClass >> IO streams (also note the coding reference, not just the sign for "much bigger/better").

I still didn't have time to test that, but what do you mean with import? Did you want to say include instead?

Every C++ project has directories that search for Header files (*.h) and Library files (*.lib). You either need to A) add a directory to your project that contains the headers & lib file or B) copy the lib file and header files into the directories the project has set.

From there, you can then include the header file into your actual code.

I did some work on this over the last two days,

turns out it was thoroughly broken when I left off, I fixed all the programming errors and actually wrote a decryption function I also made a testing project to try it out.

it doesn't work and I can't figure out why.
on decryption there is ONE byte value that isn't remapped correctly in the first block of data and all subsequent blocks are complacently wrong.
I REALLY have NO clue why this is happening as it SHOULD work perfectly unless there is something wrong with my SHA1 or Mersenne Twister implementations ( those I didn't make myself I got them as public code)

if some one who knows a bit more could have a look and see if they can figure it out that would be great.

The download has been updated

I figure out the major problem but I'l still hitting a snag, the char value FF is never decryption back correctly and I can't figure out why... wait... I think I just figure it out

HELLS YES!

It works now. I was an idiot trying to store all the values 0-255 in a array with a length of 255 when I really needed 256 :P

Ryex, would you please upload a demo with it?   :roll:
I have to study right now  :<_<:

there is a demo with it, in the folder CycleByteTest. it does use wxWidgets though...

I'll download it when I have wireless or cable internet connection. I'm using a surf stick with super mega ultra limited bandwidth  :^_^':
