| red477 01. Aug 2006 | A simple keygen from me, but I wonder if this is what the author originally want to see: I mean if the author didnt do that on purpose, they are probably bugs. part 2 of the serial - useless instructions: 0040126E |. 03C8 ADD ECX,EAX 00401270 |. 2BD3 SUB EDX,EBX 00401272 |. 33D0 XOR EDX,EAX part 3 - is this what the author want to move? 00401292 |. B8 F8E04000 MOV EAX,keygenme.0040E0F8 http://rapidshare.de/files/27795396/kg_KgMe_boonz.rar.html |

| boonz Author 01. Aug 2006 | hi, this is only some -i think it is called- junkcode. thx for your kg! |
| cobrasniper555 01. Aug 2006 | Okay, I found a serial for my name and I am sure I have the right format for coding it in C++, and when I made my keygen, the serial outputed it close to the correct one, but not completely. Could someone maybe give me a hand on this? (If I'm asking for something illegal on this site like this, go ahead and erase it and notify me :D) |
| boonz Author 01. Aug 2006 | if you could state your problem a little more detailled and tell us what part of your serial is incorrect, we might be able to help you. |
| cobrasniper555 01. Aug 2006 | Well, it's rather complicated, but I'm using red477's ASM to correct my C++, because I see a couple parts where I f***ed up on, :P . But thanks for trying to help and thanks for the keygenme, it wouldn've been my first on my own! But then I got stuck, lol. Thanks! |
| cobrasniper555 01. Aug 2006 | Okay, I got my keygen, now...I need a solution.txt if I'm correct(I've only written one keygenme which is still being uploaded and I've never written a solution, so please mind my mistakes :D) |
| boonz Author 01. Aug 2006 | @everyone who solved my keygenme: give it a try a submit a tuto, i'm really excited to see some results & different ways to approach it! |
| cobrasniper555 01. Aug 2006 | I have submitted a solution boonz, waiting to see if it can be put up, it includes a source for C++, a keygen and a tutorial which just took me quite a while to write! So glad, it's my first, lol. Hope everyone enjoys it, or a majority of you! :P |
| boonz Author 01. Aug 2006 | hello folks, NaLe!T sent me a solution via email and it can be found at these locations: a) Badongo, external host http://www.badongo.com/file/1159653 b) on my homey Apache which is up, when machine is up http://boonz.no-ip.info/reversing/crackmes/KeygenMe%201/2oo6NaLe!T_Keygen.rar thx a lot, NaLe!T also a solution by cobrasniper555 is being reviewed by the mods now. |
| cybie 01. Aug 2006 | ok boonz first i wanted to write a keygen and a tutorial but uin the second thought it was like: 'Hey, Boonz already wrote the Keygen!' so the tut would be *very* short and i decided not to submit a solution and just let u know that this is the way i made a keygen out of your keygenme (i know patching was not allowed but it was not neccessary to find a serial too): 1.) Patch 401321 to a JMP 2.) 00401310 |. B8 F8DD4000 MOV EAX,KEYGEN.0040DDF8 <-- the complete serial is located at 40DDF8 so u just have to patch at 401338 from a PUSH 0040DC03 to a PUSH 0040DDF8 After these simple patches are made the serial is moved to the textbox instead of the goodboy message Now u just have to enter a name and click check to get a valid serial! Thats all :) |
| boonz Author 02. Aug 2006 | hey cybie, your way may sound a bit lame, but it is 100% correct & effective and since I didn't explicitly forbid self-keygenning your solution is perfectly alright. It does lead to the desired result & in case somebody needed to get this cm done for whatever reason he'd be pretty clever to come up with this. Thanks a lot for this interesting point of view. Nice job, mate *thumbsup* |
| _tbU 02. Aug 2006 | Hi, here is my Keygen-Algo for this KeygenMe. I'm to lazy to write a Keygen, sorry. The KeygenAlgo is divided in three Parts: 1) strPart1 = strlen * 19h - sum(ASC-Bytes_Editfield_1) (ASC-Bytes_Editfield_1 is the Sum of all Bytes in ASCII-Code in Editfield 1. For Example: If you Input 1234, or 2431, or !!!g, etc., you will get -102 / FFFFFF9Ah) 2) strPart2 = strPart1 * strPart1 * strPart1 3) strPart3 = 41720F48h (If no relocation :-) ) Now you can create the Key: strKey = "Bon-" + strPart1 + "-" + strPart2 + "-" + strPart3 |
| boonz Author 02. Aug 2006 | ho, your solution is fine, right but I'd nevertheless like to see a solution + a compiled keygen. Remember, not everyone can sum things up that easily, so the real newbies would probably be thankful for a full-scaled tut! |
| cobrasniper555 02. Aug 2006 | I submitted one like 2 days ago, but it hasn't gotten up yet, the mods are a little slow or something.... |
| zairon Moderator 02. Aug 2006 | The crackme is very easy and in this case I prefer to wait some days before approving something. When I have some solutions I'll check them approving only few, the better ones. I can approve all the solutions but it doesn't have much sense to read 5 or 6 identical solutions. |
| cobrasniper555 02. Aug 2006 | Oh, okay, I didn't think of it that way, well, okay, now I understand. |
| [:.NaLe!T.:] 03. Aug 2006 | @Boonz: I've sent you fixed version of keygen. Now it should work in the Firefox too... Have you checked it? Poz |
| boonz Author 03. Aug 2006 | Nah, NaLe!T, I ain' got nothin' yet. Perhaps it's still about to come yet? |
| jdxyw2004 04. Aug 2006 | It is very simple.I have done it.This is my first try. |
| toshimi 04. Aug 2006 | only for XP?. :( |
| boonz Author 05. Aug 2006 | @toshimi I really don't know, I can't test it on other OS, my apologies! @Solvers Good job, everyone, quite interesting solutions :) @zairon nice selection ;) |
