| Zerith 27. Apr 2009 | If you enter nothing for the user id you get the win message :) |
| DoomsDay Author 27. Apr 2009 | Apparently, but for the wrong reasons x) I forgot to force EAX to a different value in case the lengths do not match. |
| Zerith 28. Apr 2009 | ARGH! you convert the user to binary, and then comes a decryption or whatever routine for the key which is awfully gigantic and i can't be bothered checking it. |
| DoomsDay Author 30. Apr 2009 | Just out of curiosity... Is there anyone that is still working on this one? |
| kao 30. Apr 2009 | It's not much different from your previous crackmes, so the "entertainment factor" is quite low... ;) I'll play with it when I have some free time but most probably will not write a full solution. |
| DoomsDay Author 30. Apr 2009 | Fair enough; I think you'd like the division =) |
| cobrasniper555 16. Jun 2009 | Okay...I'll say it now. DoomsDay, you've made a scary crackme. Haha. I looked at the algo and almost went running for the hills. But I soon just decided to copy mnemonics straight out of the disassembly, change addresses and inputs, and throw it into my own keygen template. It creates valid serials now... Frightening crackme from a quick glance but it was a little easy to solve. Keep it up though, I almost gave up after one second! =D |
| DoomsDay Author 25. Jun 2009 | I'm glad to see you made it through :) |
