This question already has an answer here: Exploring and decompiling python bytecode [closed] 6 answers let's suppose we have a python string(not a file,a string,no files) TheString = "k=abs(x)+y" ok? Now we compile the string into a piece of python bytecode Binary = compile( TheString , "<string>" , "exec" ) now the problem: how can i get from Binary , supposing i don't know TheString , a string that represents the original string object? shortly: what is the function that is opposite to compile() ? Without the source code, you can only approximate the code. You can disassemble the compiled

Why is signature verification on remote server more secure than on device?

陌路散爱 提交于 2019-12-01 03:46:41
问题 The Security Controls section in the In-app Billing overview instructs to perform a "signature verification" at a remote server rather than in the app (running locally on the Android device): By performing signature verification you can help detect responses that have been tampered with or that have been spoofed. You can perform this signature verification step in your application; however, if your application connects to a secure remote server then we recommend that you perform the signature

问题 Could anyone recommend a good BAML Decompiler / Viewer besides BAML Viewer plugin for Reflector, which doesn't handle path geometry/data? 回答1: You might like to have another look at the BAML addin for reflector as it's been recently updated by Andrew Smith. Have a look at his at blog post you'll note that he has fixed the issue with path data. 回答2: You can try this one by Cristian Ricciolo Civera. I did not want to use its ClickOnce installer, but the CodePlex site provides a zip file for

How to decompile an exe or a dll to assembly

北城以北 提交于 2019-11-30 13:23:09
问题 I am really interested in assembly language and I want to learn about how exe files work how dlls run etc... and I have an idea of writing an application to decompile an exe to assembly code since i am not a very good assembly programmer and with the lack of knowledge of the inner working of exe I couldn't do it. Since I can read an exe in hex i think it is not impossible but I don't know how to write my own program. Any resources or any help would be appreciated. 回答1: I think you're looking

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I've used DJ Java Decompiler, which has a handy GUI, but it seems as if the latest version is only a trial and forces you to purchase the software after some period of days (I recall using an earlier free version about a year ago at a previous job). I'm aware of Jad and Jadclipse, but what I loved about DJ Java

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . Someone just sent me a decompile of a program into C. It was a very good decompile, producing nice, mostly readabe C code (if you overlook the fact that none of the variables or functions had a human-readable name) that mostly looked like it would actually compile. There was one big problem, though. I happen to

How to change already compiled .class file without decompile?

夙愿已清 提交于 2019-11-30 11:52:47
问题 I want to change .class file's method. I installed JD Eclipse Decompiler and opened the .class file. I added some codes and save .class file. But, .class file is not changing.

Regards EDIT: Here is my decompiled code: /* */ package org.hibernate.id; /* */ /* */ import java.io.Serializable; /* */ import java.sql.ResultSet; /* */ import java.sql.SQLException; /* */

Enumerable.Sum() overflowing

試著忘記壹切 提交于 2019-11-30 11:51:14
Hey, I'm using the Enumerable.Sum() extension method from LINQ to compute hash codes, and am having a problem with OverflowExceptions when the code gets big. I tried putting the call in an unchecked block, but that didn't seem to help. The MSDN documentation for the method says it will throw if the value gets too big, but I checked in reflector and this is all there is: public static int Sum(this IEnumerable<int> source) { if (source == null) { throw Error.ArgumentNull("source"); } int num = 0; foreach (int num2 in source) { num += num2; } return num; } Based on this decompilation, I would
