When we have enough free software
At our call, hackers, at our call,
We'll throw out those dirty licenses
Ever more, hackers, ever more.

Hi all,
This one got rejected by phrack and I couldn't be arsed to rewrite it so it
would make the next edition:
"Writing IA32 Restricted Instruction Set Shellcode Decoder Loops" by SkyLined
( http://www.edup.tudelft.nl/~bjwever/whitepaper_shellcode.html )
The article addresses the requirements for writing a shellcode decoder loop
using a limited number of characters that limits our instruction set. Most of
it is based on my experience with alphanumeric decoders but the principles
apply to any piece of code that is written to work with a limited instruction
set. (It's a continuation on rix's and obscou's work for phrack).
Comments and questions welcome, but I can not guarantee an answer to n00b
questions.
Cheers,
SkyLined
