Hello. I am writing a program (laboratory work) in which an assembler insert is needed. I am not familiar with the assembler myself, so I could be mistaken with the wording.

In general, it is necessary for the assembler insertion to save a dump of the code segment to the hard disk.

On the Internet, I found a piece of a program that encrypts a code segment:

use32 ;ROR section mov ebx, ${start+pack_len-1} mov ecx, ${pack_len-1} ror_loop: mov al, byte [ebx] ror al, ${key_encode} mov byte [ebx], al cmp ecx, 0 jz stop_loop dec ebx dec ecx jmp ror_loop stop_loop: ;GO OEP push ${original_eop} ret

The fact is that the assembler insertion, which I cited above, is used in the python program. Only, this insert encrypts the code segment, and I need it to save the code segment to the file. And since I have no experience at all in assembly language, I ask you to help.

Closed due to the fact that the essence of the question is incomprehensible to the participants insolor , torokhkun , cyadvert , zRrr , sercxjo 15 Nov '15 at 20:14 .

Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

    @ReinRaus is a very interesting question. I just did not hear about translators with assembler inserts on FASM. - alexlz
  • @alexlz: What's the problem? Compile into the object file, connect at the linking stage, business. - VladD February
  • @VladD Apparently I am very behind the times. I always thought that the compiler, and not the linker, dealt with assembly inserts. - alexlz
  • @VladD wikipedia also lagged behind: Assembler insertion - alexlz
