| Tenshi 21. Sep 2006 | on debugging it makes memory errors is that normal ? i have unpacked how its told in .nfo greets |
|---|---|
| HMX0101 21. Sep 2006 | that's because it have smc (self modifying code) :) i have solved it, sometime ago... |
| lord_Phoenix Author 21. Sep 2006 | smc is here, yep ;) but i was drunk, etc. when setted four-level of difficulty.. it's more easier %) |
| kaiZer-by 21. Sep 2006 | it is not an easy crackme by lord_Phoenix. Previous crackmes was an easy. Thank you, lord_Phoenix! |
| HMX0101 21. Sep 2006 | it's easy if you know basic crypto :P hehe |
| kaiZer-by 22. Sep 2006 | 4 me it's not an easy! |
| Guetta 10. Dec 2006 | easy to find a serial/name, but not so easy to keygen ;) I'll try to make a keygen soon. Thx lord_Phoenix |
| kaiZer-by 12. Dec 2006 | Guetta, do you have a serial for your name? If you have, please send it me! |
| Ox87k 12. Dec 2006 | wtf?! kaiZer-by, isn't u able to find a valid serial for ur name? |
| Guetta 12. Dec 2006 | Sorry KaiZer-By, I can give u some hints, but not a serial, it will not be appreciated for a trial, I think... |
| kaiZer-by 13. Dec 2006 | 0x87k, I can't find a valid serial for my name!.. too bad! =) |
| Ox87k 13. Dec 2006 | 'cmon it isn't too hard! Phoenix said us that was drunked when he setted 4 as level! Study the basic of crypto (rsa, md5, base64 :P) and apply it here.. ;) |
| kaiZer-by 16. Dec 2006 | 0x87k, yes, I know it! Maybe I'll study the BASiC of crypto.. maybe (if i'll have some time). |
| mucki 23. May 2007 | I thought it is not allowed to post a solution |

| boonz 23. May 2007 | I'm sorry for the inconvenience... |
| zairon Moderator 23. May 2007 | No problem :) |
| andrewl.us Moderator 06. Apr 2008 | What are "Cauchy's Cryptsig" mentioned in boonz's solution? And how did he know that one call was MD5 with modified constants? Yes, there are several dword mov's in a row, but still, how do you guys recognise when it's a certain hash algo? |
| Ox87k 06. Apr 2008 | @andrewl.us: The "Cauchy's CryptoSIG" is a signature file for IDA. With this one you can recognize many hash algos using IDA. Here is the homepage (i think this project is a little bit old now): http://www.cryptosig.prv.pl/ You can recognize the hash algos with PEiD's plugin called "Krypto ANALyzer" (Kanal) or with a program like "Crypto Searcher" by x3chun. |
| andrewl.us Moderator 06. Apr 2008 | Ox87k: I thought KANAL Plugin, Ilfak's FindCrypt, and the like all identified algorithms simply by the constants they used - in this case the constants are wiped out, so are some advanced crypto scanners actually doing code analysis? |
