When you open the software, you see a variety of registration and unregistered tips, there is a desire to conquer it, and is very thorough kind of.

Idea one: Generate serial numbers

If I can generate the serial number according to its encryption algorithm, it will not change the original program. Generating machine code is relatively simple, the registration class has a function to verify the serial number, but does not tell how to generate serial number, should only the author validate algorithm and tools to generate serial number. This verification function is to encode and decode the serial numbers in various ways:

Finally stuck on the formbase64string function, you can go to MSDN to get a look at this function. I choose to give up this method.

Idea two: Change the key jump

As before, to find the key jump, and then modify it, ok! can be the end of the story I did not guess: I originally thought to locate in the Register function, "Isvalid=flag2&&flag" changed to "isvalid=! flag2| | Flag ", after repeated modification, still do not use, finally I also inserted a MessageBox here to query the value of the IsValid, the results did not show out at all. So it should be if there is no execution, forget it.

Idea three: Completely modify the function

The key to this program hack is the register (string serialnumber) function in the Globalcontrol form, which returns a type of Registerresult. This type is defined as follows: IsValid indicates whether to register, to be changed to T Line; ValidTo, registered to a long time, that is, after the expiration date, change 10,000 years.

Here's how to modify it:

Navigate to the Register function, right-click on the IL Code of Reflexil and select "Replace all with code ..."

Open the Compile dialog box and modify the

Modify the code (to ensure that the syntax is not a problem OH), click on the lower left corner of the "Compile", if there is no grammatical problem, the right will generate IL code, click OK. Such as:

Now, the software starts to show registered to 2115, using the registration window, do not enter anything, are registered successfully.

The encryption method for other software is the same, the key is the register (string serialnumber) function in the Globalcontrol form ...
