| Guetta Author 07. Jun 2012 | Hi ! Yes, to register you need an Internet connection :) |
| Guetta Author 07. Jun 2012 | @ranyeva: Please, read your PM's and stop investigations here. |
| redoC 17. Jun 2012 | "Invalid activation code" ...pls give me a tip, how to construct last group of numbers in activatin code? should we use bruteforcing? |
| Guetta Author 18. Jun 2012 | Well done, you've done the first part :) Okay, so you want a hint, let's say that if the last part is not controlled by the program but directly sent to the server, we can suppose that the server is only gonna focus on this part of the activation code. And since you can't know what the server is doing, yes, you should code a bruteforce. But it can be a little challenging to bruteforce something when the returned value is dynamic ;) |
| Guetta Author 20. Jun 2012 | Excellent analysis of all the concepts inside HMX0101, good job mate ! |
| lovejoy226 21. Jun 2012 | It's reaally hard, but I appreciate your submission. so I could see the solution. hmx0101. Thanks. |
| Guetta Author 28. Jul 2012 | Nice work on this redoC, thanks for your solution. |
| redoC 17. Dec 2012 | just little note: my keygen uses GetSystemTime()+2 for hour computing which sometimes not corresponds to the server time... so it should be altered additionally |
