| Ank83 25. Jan 2006 | Is it me or this crackme in the stage one take only numbers betwen 0 and 11 ? |

| Ank83 25. Jan 2006 | Need help. What does SAR function do. SAR EAX, 0A ? If I have 100 004 in EAX it give me the value of 97. What does SAR do. Thanks Ank |
| thrall 25. Jan 2006 | SAR is shift arithematic right. SAR EAX,0A means shift contents of EAX by A(10 decimal) bits to the right. |
| HMX0101 25. Jan 2006 | some info: "SAR Shift Arithmetic Right; Intel 80x86; shifts the contents of a data register or memory location (8, 16, or 32 bits) to the right (towards least significant bit) by a specified amount (by 1, by 0 to 31 bits specified by an immediate operand, or by 0-31 bits specified by the contents of the CL register), with the low-order bit being shifted into the carry flag, the original high-order bit being replicated and shifted into the high-order bit; sets or clear flags" extracted from: http://www.osdata.com/topic/language/asm.htm |
| Ank83 25. Jan 2006 | Thanks. I understand the algo of this crackme I wrote a tutorial, and I was thinking to write a keygen tomorow on work. But the problem is that on the machines on work we have only VB. And SAR is not implemenetd in VB. To write the function will need me more than 2 hours. :P Thanks to all ! KLiZMA nice work. Keep going ! I like the fact that in every new crackme you add something new. |
| HMX0101 26. Jan 2006 | I think that Visual Basic can manage assembler |
| KLiZMA Author 26. Jan 2006 | Phanx: Ank83 - questions HMX0101 - answers |
| HMX0101 26. Jan 2006 | i'm working in the keygen |
| HMX0101 28. Jan 2006 | yes, it is a bug because, if the ID is less than 0x1869F, close the crackme, and if the ID is greater than the 3rd serial close the crackme, but the autor says in the readme: "4. no self-keygenning and 'all accept' patching" Regards, HMX0101 |
| KLiZMA Author 02. Feb 2006 | DON'T BE STUPID! THERE IS NO BUGS IN THE CRACKME!!! TRY TO SOLVE IT AGAIN, TAKE PIECE OF SHEET AND SOME BRAIN... I HOPE THAT THE GOOD SOLUTION WILL BE POSTED! |
| Ank83 02. Feb 2006 | Stage one: condition 1 for first entered values Stage two: condition 1 for new entered value Stage three: codition 1 for first entered values contition 2 for first entered values So this means you can pass the two levels, but in the third stage you have new condition for the before entered values. So when writting a keygen you must create values that valid for all conditions. I think that this is the problem that is confusing you. I cant write keygen becase all the language I know didn't implement SHR. I didn't know to program in ASM so well. Regard Ank83 |
| CuTedEvil 02. Feb 2006 | as KLiZMA (the author) said, the crackme is not bugged. It has been tested. guys, you have to analyze the crackme more carefully :) |
| Ox87k 02. Feb 2006 | no no read with more attenction my posts: QUOTE: sorry, i was confused!!! delete my post plz, is not correct!! eheh, lol ^^' however... My solution, write some time ago, was rejected because my dumped file don'w go in other machine and i don't know. In my 2 pc it work perfectly. ZaiRoN said me that the call SetUnhandleExceptionFilter in his pc point in a another area and i don't understand because in my pc work. ImportRec don't show me one call sospect or invalid and the rebuild of iat is good. If u want a keygen+tutorial i'll re-send my solution and maybe will be accepted. |
| KLiZMA Author 03. Feb 2006 | to Ox87k: BaD MessageS DeleteD ! |
| CuTedEvil 03. Feb 2006 | Ox87k, ur solution was invalid. as ZaiRoN told you, dumped file isn't valid. (on my machine too). Try to fix this, or find another way to correctly unpack. Ur solution should be accepted then :) |
| Ox87k 03. Feb 2006 | yes cutedevil, my dumped crashed in all other machine but in my 2 pc work perfectly. Really, i don't understand how to make a valid dumped file... only 1 import is wrong... :( |
| KLiZMA Author 04. Feb 2006 | to Kerberos: Pnanx! Very intelligent solution! |
| KLiZMA Author 16. Feb 2006 | to Ox87k: With big cruelty! Thanx... |
| HMX0101 16. Feb 2006 | i have some problems on the 1st serial, somebody can help me? |
| Ox87k 16. Feb 2006 | to Klizma: i would shot u because the dump of ur crackme has made me to become crazy!!!! :P sorry for the delay of the solution but I've had problems with the dump file! Anyway, thx for this crackme! I'm waiting for KLiZMA Crackme#5 ;) |
| HMX0101 16. Feb 2006 | i'm waiting the crackme #5 :D |
