Although, in C, you could have written (Var1*Var2)*(Var1*Var2) // note the expression without an assignmentīut your compiler would normally throw away the first line of this. Also, it shows that there's no good translation to a high level language, because you don't generally calculate anything in them without using the result. If this was a homework question, i'd assume your teacher wanted to see if you're paying attention to detail. The hexray plugin will mark this pointer as a DWORD/int etc. The steps could be: Convert the insterested function to poseduo C code. So, your code calculates (Var1*Var2)^2, but then assigns Var2 to Var3, not the calculated result. 1 The effective way to analyze virtual function table based program is to change types using ida hexray addon. Imul edx, eax edx=edx*eax (=(Var1*Var2)^2)

That said, as you have only 2 opcodes, one of which is mov which is the equivalent to an assignment: mov edx, Var1 edx=Var1 Of course, a high level language implementation of something might be easier to read than assembly, so translating to high level might be a part of the work, but it's not the biggest part in most cases.

That guy meticuously translated a lot of assembly to C and wasn't any wiser in the end, he could have saved himself 2 months if he had been able to recognize the RSA algorithm from the code. For example, a year ago, someone asked this series of questions. And even for compiled code there may be no good translation if the code was heavily optimized.Īlso, note that reverse engineering is not about translating assembly to higher level language, it's about figuring out what's going on. Please note that there is no general 1:1 relation between assembly code and a higher level language, especially if the assembly was crafted manually.
