How to convert ASM to read-able code?

I have an exe which I have opened with PE Explorer Disassembler. Now I can see the asm code, which looks like that:

    push    ebx
    push    esi
    mov ebx,eax
    mov eax,[ebx+38h]
    push    eax
    mov eax,[ebx+3Ch]
    push    eax
    mov ecx,edx
    mov eax,ebx
    mov edx,[ebx+30h]
    mov esi,[eax]
    call    [esi+7Ch]
    or  byte ptr [ebx+00000088h],02h
    pop esi
    pop ebx
    retn

I have no idea what that means. Is there a way to convert this now into read-able code (C, C++, C# or VB.NET)?

Background info: The reason why I need this is because I need to call the above function from my windows app. Now this function resides in the third party exe - there is no API or source-code for it. Any help or advice is appreciated.

Solution

  • What you want is called "decompilation".

    That is not easy to solve task, and often not possible at all. You might try Google as a start.
