reverse-engineering

问题 Hibernate can be used to generate all DAO's and hibernate properties files using reverse engineering. But the DAO code it generates is not appropriate in terms of spring dependency injection. So, how can we use hibernate reverse engineering technique to generate spring beans based on principle of dependency injection? 回答1: You should use a generic DAO, where you only need to create a Subclass that specify the entity class. Or a more modern approach like Spring Data JPA or its predecessor

问题 To calculate CRC I found a piece of code but I am not understanding the concept. Here is the code: count =128 and ptr=some value; calcrc(unsigned char *ptr, int count) { unsigned short crc; unsigned char i; crc = 0; while (--count >= 0) { crc = crc ^ (unsigned short)*ptr++ << 8; i = 8; do { if (crc & 0x8000) crc = crc << 1 ^ 0x1021; else crc = crc << 1; } while(--i); } return (crc); } Please any body explain and tell me the logic. 回答1: This looks like a CRC (specifically it looks like CRC-16

问题 I have to develop a plugin for a program that uses dongle to activate.Just wondering can i crack the key of the usb or something else? 回答1: I'm sure you can , but you might be running afoul of the various legislation regarding the act of reverse engineering content protection systems. I am, of course, referring to the American DCMA statues. In any event, as pure thought experiment, I might try the following: Clone the USB firmware image, and load it into a virtual USB port As you say, crack

问题 I am currently trying to reverse a program under Linux that has a bunch of anti-debug tricks. I was able to defeat some of them, but I am still fighting against the remaining ones. Sadly since I am mediocre, it is taking me more time than expected. Anyway, the programs runs without any pain in a VM (I tried with VMWare and VBox), so I was thinking about taking a trace of its execution in the VM, then a trace under the debugger (gdb) and diff them to see were the changes are and find out the

问题 I have a finished cordova project and i want to use proguard inorder to prevent others from reverse engineering the APK.But i have trouble doing this. In http://developer.android.com/tools/help/proguard.html It says that "When you create an Android project, a proguard.cfg file is automatically generated in the root directory of the project. " But i cannot find a such file. So how do i apply proguard to my app? Thank you 回答1: You need to uncomment below lines from your project.properties file

问题 I'm trying to code my own, private interface for asking questions on Stack (without using the API, which requires an account, which defeats the point of having some minimal amount of anonymity), because I strongly prefer to have my own form in my own "control panel" where I can type it according to my own setup. After spending countless hours on this, I have come to the conclusion that Stack entirely refuses anyone trying to post without JavaScript enabled. When JavaScript is enabled in a

问题 I'm implementing a performance analysis tool. One thing that I'm doing is to estimate the cost of a function call. In order to do that, I need to know if a given function is virtual in a shared library. For that, I have access to the shared library assembly. I have also a call graph of the execution. I cannot make anything during the execution, the analysis has to be done after the execution using the information I can obtain from the call graph and the shared libraries. The only way I've

问题 While dumping heap of a win32 processes (Mostly in process which has high heap memory consumption like IE ) using !heap -a 004e0000 I find multiple segments of a particular heap like , Heap entries for Segment00 in Heap 004e0000 Heap entries for Segment01 in Heap 004e0000 Heap entries for Segment02 in Heap 004e0000 My questions are Question 1. Why its necessory to divide single heap into multiple segments ? Question 2. Most of the times I find a large gap between two segments. For example in

问题 I'm currently working on analyzing some android malwares and i need to decompile APK files. Reading an answer and many other answers like it, i know that we can extract java source code and other resources, create a new project and put those files in, make some modifications and compile the project. Is this approach applicable to every APK file ? If we aim to make very little or no modifications in the java source code, does this approach work for every APK file? If not, what is the main
