I want to make a encryption program. Any suggestions are welcome

[Sycron]

So, if i have a file, i may copy his 0's and 1's in a 3dim matrix and with a key to rotate parts of that matrix.

It's a good idea ?
Thanks.

unless you are doing this as practice / just for fun, i really woulden't....programs like truecrypt already exist for encrypting drives/files

If you are going to make your own algorithm, you are gonna need very good math knowledge; crypthography etc.
If you are interested in the implementation, look up some already prooven algorithm (not source, just how it works) and try to implement it on your own.

Then, i have to learn some math ... :| do you know some good websites ? I think at school i wont learn something interesting in that domain... I really like crypthography. And i'm just 16 years old... but it doesn;t matter i want my crypt algorithm...

I haven't gotten to learn cryptography yet (at the university). But when I think about it, you don't actually need super mega awesome math skills to make a simple algorithms. Sure it wont be the bestest uncrackable algorithm, but it will be a good experience. Still, make sure to check out some simpler algorithms to get ideas, then you can do it yourself by applying what you have read.

I would say join the truecrypt forum, and look at their code for examples. It is open source...

If you are interested in crypto, pick up Applied Cryptography (http://www.schneier.com/book-applied.html) by Bruce Schneier. You should be able to find it used on Amazon or eBay or you might even be able to get it at your local library.
