Cracking WingIDE pro version 4.03

For python programmers, WingIDE is certainly no stranger. Its powerful functions have become my favorite python development IDE,

However, this software needs to be registered. We have been using wing IDE 3.2, and we have been using a 10-day online registration server.

The method is applicable to all wing IDE versions. Record this method and hope

It is useful to everyone, but I still hope you can purchase genuine software. After all, it is not very expensive.

 

This process is a brute-force attack and does not involve registration algorithms. If you are interested, you can study it yourself and share it with me.

Download and install the latest version from http://wingware.com/pub/wingide/4.0.3/wingide-4.0.3-1.exe,

Obtain a 10-day trial License after installation. Open your wingide installation directory C: \ Program Files (x86) \ Wing IDE 4.0 \ bin \ 2.5,

The token for registration verification is in this src.zip package, and the abstract. pyo file under the process directory is extracted. My goal is crack.

Abstract. pyo is a file optimized and compiled by python, which contains bytecode and needs to be analyzed by disassembly.

Here, I will describe how to analyze it and then crack it.

First, how to disassemble:

Go to http://pypi.python.org/pypi/unpyclib/0.8.1to download

This unpyclib python library is decompressed and decompiled,

Python application. py-d abstract. pyo> abstract.txt

Now, we have analyzed this counter to compile abstract.txt. The function we need to pay attention to is _ GetTermDaysLeft.

I will not go into details about how to read and analyze bytecode disassembly instructions. I will read some resources to learn,

STR: '_ GetTermDaysLeft' (10 00 00 00 00 5F 47 65 74 54 65 72 6D ...)

Now, copy abstract.pyoto this src.zip file, and use 7zipto Delete abstract. pyo in process in src.zip first.

Modified abstract. add pyo to the original C: \ Program Files (x86) \ Wing IDE 4.0 \ bin \ 2.5 directory, restart wingide, and check your Help-> About

The License in it, the above time is already unlimited, can be used without time restrictions.

 

I upload src.zip TO THE http://skyme.tk, download the address below, replace the original installation directory

C: \ Program Files (x86) \ Wing IDE 4.0 \ bin \ 2.5src.zip.

Enjoy it :-)
