Hi there. I wrote a new essay on cryptography. It's a personal interpretation of an article i've read on cryptography in the scientific magazine EOS. You can read it on my site: http://blackb.tsx.org, in the security section in the right column.
Later on, my essay will be available on this site
Plz send me your opinions, so i can improve the essay, or publish additional notes other people send me.

you may want to check this out too (for RSA basics, good introduction to newbies).

that doc. 's really good. i think i'll publish it on my site.
thx

Considering the pressure I have here, I had to publish it on the mirror too
It's really a good one,maybe someone could send a related one if he managed to reverse this kind of annoying protection :

In asprotect (again I know...) you can encrypt part of app by putting
some delimiters inside your source, compile it and asprotect will encrypt your code between those delimiters. Then the key to decrypt
is feeded by a reg entry or text file that is provided when you buy the license.

IMHO, nobody managed to reverse this, I know it's elliptic curve encryption scheme, I don't even think about bruteforcing this, I'll die
before my poor amd 600 will ever manage to decrypt a single instruction of code. This seems again an impossible task to do, except buy buying the license and dumping the decrypted code inside the unprotected target.

Have a look here:

and grab ""Block Ciphers and Cryptanalysis",
by Fauzan Mirza, its a very interesting and well
written paper about block ciphers.

Have fun
