| boonz 01. Jan 2007 | is a self-keygen ok, too? algo is pretty long... |

| cektop. 06. Jan 2007 | Hi, I don't know if this crackme has a neat trick or it's just a bad piece of coding. Anyway, I've written a keygen which works for me, but I noticed that serial generation depends on 2 registers which are not set so they have random content. So I'm pretty sure this keygen won't work on all computers. kaiZer, comments? |
| boonz 06. Jan 2007 | haha, cektop, just my problem, luckily zairon noticed! i'm in contact to kaiZer, and it seems he did that unintentional! |
| kaiZer-by Author 06. Jan 2007 | I don't know why the serial generated difference! No comments ;) |
| jB_ 06. Jan 2007 | I noticed the same problem. Initialize all your variables and it will be ok, kaiZer-by. |
| boonz 06. Jan 2007 | just out of curiosity: is it keygenable in the current state? |
| cektop. 07. Jan 2007 | It's always keygennable you just need one starter variable (initial value of EBX register). kaiZer, if you don't tell me I'll just consider this a coding error. I'm not going to get into how value of EBX gets there if you're just trying to cover up buggy code. |
| boonz 07. Jan 2007 | How can it possibly be keygenable if the initial value of ebx varies between different computers? |
