| Seco_1 05. Dec 2005 | I've been working on this crackme and I have some questions. Havent been doin this very long, they might sound stupid :) Anyways: It seems that the prog generates a different correct serial for the same name each time it is run. How then can you make a keygen without patching? Or is patching the only way? Or am I missing something? Or is this a bug? What was the rating before it was changed to 1? |

| Shism Author 06. Dec 2005 | This is a keygenme and patching is only allowed to make a self-keygen...... Meaning making the program spit out the correct serials itself. Im sorry if the algorithim ( I rock) is uncrackable or is it???? |
| Shism Author 06. Dec 2005 | Admins you can increase the difficulty as high as you deem necessary... Because I am using a "uncrackable" algorithim ; ). And Don't start bashing me people |
| Shism Author 06. Dec 2005 | There should be a difficulty rating of 10 for this crackme! P.S : Joke :( I know it was lame... |
| ultrasound 06. Dec 2005 | Shism, I still stand by the fact that using random number, however uncrackable, is not realistic for a protection scheme, which is what crackmes are supposed to represent.. even if the app is self-keygenned it can never produce a valid serial.. If a protection scheme is to work, then the author of the program should be able to generate and distribute working serials for their application, here this is not possible. I know you said you would accept my self-keygen but I havent got around to finishing it yet as I had problems trying to display floating point number in a message box and havent had time to look again since.. The problem is even with all the effort to keygen the app a keygen is still worthless, its like asking 'what number am I thinking of?' ... '5?' no I was thinking of '123'.. 'what number am I thinking of now?' |
| Shism Author 06. Dec 2005 | No one said it would be impossible to use this in a real life protection scheme.... There are possible ways to do it... |
| Knight 06. Dec 2005 | I haven't looked at this, but well in TheHyper's sixth crackme there was also used random numbers. Just the seed was not random. Duno, but maybe here's the same. Just a guess... Regards, Knight |
| deroko 06. Dec 2005 | yup you can fish key at fcomp qword ptr[ebp-34] but it will change all the time. solution is only to patch, I don't see any other option, even coding loader to get key won't help... |
| Shism Author 06. Dec 2005 | Yes only way to crack this is a patch....I was trying to see if this was keygennable and it isn't... So you can take off 1 and 2 crackmes of mine..If everyone think's its impossible to crack this without a patch. |
| Shism Author 07. Dec 2005 | The purpose was to see if anyone could crack the random number generator.... Plus This is a keygenme ..... not a patchme |
| deroko 08. Dec 2005 | sure, keygenme that cannot be keygenned |
| Shism Author 08. Dec 2005 | That is correct :) |
