======= PyAsm

:info: An inline x86 (64bit pending) assembly module for python! (on windows!) :Author: Amihai Neiderman

About

The PyAsm is a python library intended for the execution of a native x86 assembly code through python code. The idea came to me one day when I needed a fast way to locate the address of the PEB(Process Environment Block) in a given process using python code. Using asm it takes exactly one line of code "mov eax,[fs:30h]" and with ctypes it takes a lot more and require you to go through a couple of semi-documented nt APIs :\

Installation

For now I don't have a real installation...So everything has to be done manually!

1. Download the lastest NASM assembler from http://www.nasm.us
2. Place pyAsm.py in your working dir or your >python[version]\lib folder
3. Open pyAsm.py and edit the NASM__ variable (defualt is NASM__ = r'nasm.exe') to the current location of your nasm.exe assembler
4. Run python!

Examples

from pyAsm import * p = pyAsm(A_32BIT) #We can alse use A_64BIT and A_16BIT! p.update('xor eax,eax') #update the executed code p.update('mov eax,1') p.update('shl eax,10') r = p.run() print 'EAX is:',r.Eax

EAX is: 1024
