| astigmata 23. Jan 2006 | this one is really nice |

| CromaxX Author 07. Feb 2006 | So keygen it please =) !! (and don't forget rating it !) |
| ultrasound 12. Feb 2006 | I have a made an oraculum approach keygen for this, but for some reason it only gets valid serials when i run from within the MSVC++ environment, if I compile and run then the serial is shorter and wrong.. I cant see any code in the crackme that could be making a difference by where I run the keygen from.. CromaxX any hints? have you got some sort of oraculum protection that I have missed? |
| ultrasound 12. Feb 2006 | hmm, on second check it doesnt work in debug mode specifically, it just works from time to time, i am still trying to figure out what changes when it does work.. |
| ultrasound 12. Feb 2006 | CromaxX, when I click 'Verify' for one of my serials it says 'Not Really', but if I press return on the verify button instead of clicking then it says 'Good job' For example, username: hello serial: E86784756t796;6;34q33925:59:o4534372c3942336742z4333;4:62:Z Press 'verify' and you will see 'not really' then press enter and see what happens.. |
| CromaxX Author 20. Feb 2006 | Woh what the f*** ??? I tried your example on several Windows XP versions (32 & 64 bits) and I didn't see "What happens"... Very strange =/ ! I compiled my source code with gcc(32bits) on Windows XP 64 bits Edition, maybe if I recompile it on the 32bits win version, your bugs won't appear ? But gcc is a 32bits compiler, so it's very strange... I'll submit my new version soon ! PS : Sorry for the response time, but I wasn't at home for holidays ! |
| Zaphod 20. Feb 2006 | CromaxX: I experienced a strange behaviour of your crackme similar to Ultrasound's - I tried with name: qwerty, serial: E99696;45t3;58:952q43966:485o4693526:5c3:95:63:26z3:57326566Z The first time the program said good job, baby - the next time ( and the following ) it said not really ( ?? ) One other thing: When I run the crackme by itself, I can move the window around, quit the program or minimize it like any other program - but when I run it in Olly, I can do none of these things. The window sits permanently in the middle of the screen. I this intended or is it a strange behaviour by my computer ? |
| ultrasound 20. Feb 2006 | Ok Cromaxx Ill wait for the new version and then recheck my keygen :) |
| CromaxX Author 20. Feb 2006 | Zaphod : It seems to be the same as ultrasound, but it not appear for me : it always shows "Not really...", for the two examples you gave me, very strange... But I can tell you that the two serial corresponding to the two name aren't good (if you want a little help, you can send me a message). For the window which is always in the middle of the screen, it's a normal thing, so don't worry =) As I said before, I'll recompile it on windows 32bits, and submit it. Jut for my information, what are your OS ? |
| ultrasound 20. Feb 2006 | Im on WinXP (SP2), ill PM you, maybe I can send my keygen for you to test before I submit it here.. |
| Zaphod 21. Feb 2006 | WinXP Home (SP1). About the window in the middle of the screen - how come it's only when I run it with Olly? I don't see any Olly-checking in the program... |
| Ox87k 21. Feb 2006 | yeah now working for me =) |
| CromaxX Author 21. Feb 2006 | Ok cool =) I'll wait for the verdict of the others ^^ |
| Zaphod 21. Feb 2006 | ok, that helped - it's a normal window now :) |
| Rambo 23. Feb 2006 | Rambo E86784687t79725966q33926935;o452432;c39422;8:78z53459;526Z I don't understand why I use Olly the work's fine , but if I open normal "KeygenMe #4" then doesn't work. ???? |
| CromaxX Author 23. Feb 2006 | Have you got the new version compiled in 32bits ? |
| Rambo 23. Feb 2006 | Yes I have the new version. |
| CromaxX Author 23. Feb 2006 | Very strage... It seem that the others haven't got any problem since the release of the new version. Do you execute it on windows XP or 2k? |
| Rambo 24. Feb 2006 | windows XP SP2. Hmm maybe I will install SP3 (polish service pack ;) ). |
| Rike 26. Feb 2006 | Name: Rike S/N: E7386;;84t5;478286q98::5932o5947792c39787;4438z3:57326566Z Same here, different results with the 'Enter' key, probably a different hash function. I think I'll stick to the good-ol' 'Verify' button. |
| CromaxX Author 27. Feb 2006 | woh that's a very strange bug !! It never appears in the precedents crackmes ! I'll search for the source of this bug. Sorry... |
| l0calh0st 01. Mar 2006 | Self keygen http://d.turboupload.com/d/397100/Keygen_d4_by_CromaMax2.rar.html |
| CromaxX Author 05. Mar 2006 | Rike : I don't see any bug on several computers, so I can't resolve it for the moment, I'm sorry :/ l0calh0st : Are you sure your little keygen is working oO ?? |
| acidflash 05. Mar 2006 | l0calh0st: keygen not working here.. nothing in serial textbox after generate |
| ultrasound 05. Mar 2006 | Id be interested to know when u resolve bug cromaxx, I can send u my oraculum if that helps in seeing some bad serials being generated.. :) |
| l0calh0st 05. Mar 2006 | It was fine...Anway here is much much better than previous one ;) http://rapidshare.de/files/14747629/keygen_original.rar.html Keygen algo is so long |
| HMX0101 05. Mar 2006 | l0calh0st: the selfkeygen not works. |
| acidflash 05. Mar 2006 | l0calh0st: your new one doesn't work here either, just inserts a garbage char in serial textbox when I click generate. I have one working here (all my machines), maybe others can test? http://rapidshare.de/files/14781760/INTERNAL_KeygenMe__4_by_CromaxX.rar.html |
| acidflash 05. Mar 2006 | Note: make sure you click generate button! |
| acidflash 05. Mar 2006 | if that doesn't work set focus to name textbox and hit return.. it seems to make a difference :) |
| HMX0101 05. Mar 2006 | I have modified the selfkeygen of acidflash, here the things changed: - The namebox is now centered - The serialbox is now readonly - The messages are eliminated - The about button is out - The appearance is differently For generate your serial, press once time enter copy and paste in the keygen and press twice times enter. |
| HMX0101 05. Mar 2006 | oh i have forgot the link: http://rapidshare.de/files/14789777/Selfkeygen.rar.html |
| l0calh0st 05. Mar 2006 | NOP your self kegen doesn't work on my machine :( Also mine is generating fine serials on m machine...it seems we are still missing something...If selfKeygen is troubling so much then what about KEygen :D |
| l0calh0st 05. Mar 2006 | Ok here is difference my self kegen l0calh0st E33843453;t63;6526q338;23823o32;7;2:37c3:48937958z325:;638Z your's E33843453;t5697:54q39;6;2999o3:3;:6775c3:6427822:z3:57326566Z The first one is working fine on my pc |
| HMX0101 05. Mar 2006 | press enter until generate the same serial that you :D the keygen generate various serial each time the button is pressed |
| acidflash 05. Mar 2006 | it seems to generate different serials depending on if you click the generate button OR just hit enter while focus is in a textbox (2 different serials).. I just tested the 'hit enter with serial textbox in focus' and got a good serial (no click of generate button) |
| acidflash 05. Mar 2006 | (testing with my orig version just so we are keeping track) |
| HMX0101 06. Mar 2006 | i have tested to disable the button and press enter to generate and this not work, this is because you hit enter always in the generate button |
| l0calh0st 06. Mar 2006 | no the serial is not correct...have you checked mine...http://rapidshare.de/files/14747629/keygen_original.rar.html and remember to CLICK generate rather pressing Enter and it is working on my pc Your kegen's serial by clicking the button E33843453;t5697:54q39;6;2999o3:3;:6775c3:6427822:z3:57326566Z by pressing enter E33843453;t532494q3:8:967;5o3:9524847c3:57946:::z3:57326566Z None of them work for me Correct serial working on my pc E33843453;t63;6526q338;23823o32;7;2:37c3:48937958z325:;638Z |
| l0calh0st 06. Mar 2006 | and you have to click the crackme button not hit enter |
| acidflash 06. Mar 2006 | l0calh0st: I get the same results with yours (latest). if I click button 1 get garbage in txtbox and if I hit return I get different garbage (no sign of a serial though).... We must be missing something, I'll peep mine again after work :) |
| acidflash 06. Mar 2006 | I just posted one I verified works as long as you click button OR hit enter (just do the same for both orig and internal). The original does do 2 different serials depending if you click vs hit return. The internal at the following url generates for both. again please make sure you click button on both OR hit return on both.. http://rapidshare.de/files/14816086/internal3.rar.html |
| acidflash 06. Mar 2006 | This was funny btw (in case anyone missed it, note the format string for serial): ASCII "C%dr%do%dm%da%dx%dX" CromaX 8-) |
| CromaxX Author 06. Mar 2006 | Good work guy !! I don't know where you take bugs from, but some of your keygens works fine (on my pc oO) : Internal Keygen by acidflash : OK Selfkeygen modified by HMX0101 : OK If you want some help, only for verify, you can ask me on PM the keygen I made for (and also look if it works in your pc too !) |
| l0calh0st 06. Mar 2006 | The new one works ok by clicking.....also mine works fine with clicking.just check it out and verify..i m getting mad..m kegen works fine on my pc http://rapidshare.de/files/14747629/keygen_original.rar.html ANYBODY PLZ CONFIRM IT remeber to clik both in self keygen and original crackme |
| CromaxX Author 06. Mar 2006 | It doesn't works for me : Name : CromaxX Serial : P †Strange... |
| l0calh0st 06. Mar 2006 | You have to click as i said not to press enter This is the one for you E;25:9632t:5::82:q4763268;6o45954969:c3:73::3782z3:57326566Z |
| HMX0101 06. Mar 2006 | maybe the crackme, has a anti-selfkeygenning trick :D |
| Ox87k 06. Mar 2006 | not hmx0101... my self-keygen work perfectly.. i test it in 3 pc. I don't send my solution because i haven't time for write a g00d tutorial but self-keygenning is possible. ;) |
| acidflash 06. Mar 2006 | localh0st: yours gives me the same problems, garbage in the textbox (clicking or hitting return just gives different garbage).. So the click vs hit enter applies to yours also, just it puts garbage in. |
| l0calh0st 06. Mar 2006 | hmm that's really strange...so the conclusion if it is so difficult to self keygen that who will made Keygen |
| HMX0101 06. Mar 2006 | the best option for this crackme is a keygen :D |
| HMX0101 07. Mar 2006 | my keygen is working, the solution coming soon... |
| ultrasound 11. Mar 2006 | I have found with some tests that the keygen *seems* to base the serial on the opcodes of itself, as when I run a patched version of the program (to match the patches in oraculum) then my serials would be correct but when I do the same breakpoints in olly with the original version it gets a different serial, Cromaxx, before I go too far into this am I on the right track or is it coincidence? |
| HMX0101 11. Mar 2006 | CromaxX, any serial that generate by the crackme is good but only work with OllyDbg putting a breakpoint in the strcmp, maybe the routine has a random number that generate different serial each time |
| CromaxX Author 11. Mar 2006 | ultrasound : I think it's a coincidence. I hadn't make some protection like that oO ! HMX0101 : No, there aren't any random number. |
| Taliesin 03. Apr 2006 | I've noticed the program acts differently depending on whether you enter name or serial first. I wrote self gen keygen, submitted to moderators. But only seems to work if you enter name first on both or serial first on both...doesn't work if you enter name first on one and serial first on the other. |
| l0calh0st 23. Apr 2006 | Taliesin your keygen doesn't work on my pc :( |
| playar 25. Apr 2006 | very very stranger... debug & release compile my code get diffrent result |
| playar 25. Apr 2006 | here is my keygen ( include sourcecode) but sorry, no tutorial http://www.panzhishi.com/crackmes.de/06-04/Keygenme4.zip |
| Taliesin 26. Apr 2006 | After discussing with l0calh0st, it seems the part I thought was constant (shl cl with cl = 6F when clicking ) isn't. Even that seems to be changing. I guess the only real way to get it working is self genning key. |
| Shism 26. Apr 2006 | your keygen me didnt work playar |
