Hi!
I would like to ask that what method does the professionals would prefer for making an application installable for only once ........like licensed applications ... I mean during the installation the registration key will be asked and after entering the key then it continues to work else it stops... How to achieve this?  Whether I should make an application that runs at installaton time and which popups a dialog which asks for registration key and then installs the other files or Is there any other standard way that is being followed for the software protection??? Thanks & Regards, Lalit |

I have successfully implemented the dialog that shows the IMEI number of the device and asks for the Key.
But I don't know how to go about the key generation code. I mean the code that take the IMEI number and generates the key code that can be checked before starting the application.
Please help.........

A simple solution to generate the key is to take the imei and encrypt something with that imei as key. So your server will take the imei and encrypt a secret. On the phone you'll take the encrypted string (which is the key) and decrypt it.If you get the secret the key is valid....if not.....The secret can be the IMEI

Read this article http://www.newlc.com/article.php3?id_article=606 , it suggests that a "secret code" based on the IMEI number may not be a great idea and it wouldnt really matter where you put the code as it can be found from the call.
But basically, your code will be cracked if someone wants to crack it. Just try to make it as difficult as you can.
