| The-God-of-all 10. Apr 2010 | Well my Keygen is ready but I can't make a Tutorial. If anyone like he can ask me for the source Code (written in C). http://thegodofall.th.funpic.de/KeygenKeygenMe.exe But why is the serial 64 Characters long and the name can have only 24 Characters? This means that the last 16 Characters of the serial are ignored. If the name has less then 8 Characters only the first 16 Characters of the Key are relevant. |
| gavin_soung 10. Apr 2010 | You mean that you can send KengenKeygenMe source Code to me? I want to know more about you keygen. I only know you use the Tiny Encryption Algorithm. And I got the key by Infinite try.(Forgive my poor English...) |

| _ghandi_ 12. Apr 2010 | Why do people have to discuss such things here where people are going to download the keygenme to try for themselves? Surely the forum is a better place to discuss such things instead of ruining it for other people? If gettting your name up there is important, write a tutorial and submit it. |
| gavin_soung 12. Apr 2010 | I am sorry, thanks to remind |
| _ghandi_ 19. Apr 2010 | I'd like to know how that works.... I submitted a solution and it was rejected because of an error in the keygen code, fair enough. Yet The-God-Of-All submits a solution which has an error in the keygen code and its accepted? Lets see, mine was rejected because it wouldnt work on strings longer than 8 chars (miscalculation on my behalf) but the solution which was accepted cannot generate a serial for a 24 char aphanumeric name? Its the last time i'll bother with a crackme from this site, thats for sure. |
| _ghandi_ 19. Apr 2010 | I should clarify, its not the keygen which has an error, but a quirk of the keygenme which prevents certain strings from being entered as a name, which then makes the keys generated for such names invalid, which has the same end result: badboy nag |
| _pusher_ 20. Apr 2010 | I did many name/serial checks with spaces and special characters.. yours didt work.. but GodOfAll keygen worked.. but apparently you found a name that doest give valid serials.. and thats why iam gonna reject his aswell. |
| _ghandi_ 20. Apr 2010 | The keygenme does not allow 24 characters if the characters are too large to be contained in the edit control, as it does not have auto horizontal scrolling. So, using the string "DDDDDDDDDDDDDDDDDDDDDDDD", we can generate a serial with The-God-of-all's keygen and it will be a valid serial in the sense that it follows the algorithm, but the GUI of the crackme will only allow 22 'D' characters and as such, you cannot enter the name and serial to validate it, as it will be truncated at the 22 'D' mark. I would like to see what combinations you tried on my second revision though, because the algorithm takes an ascii string, performs its operation on it and then the keygenme performs the inverse operation to retrieve the result, so if the ascii is printable then it should be a valid key from the second one i sent you and i limited input to 22 chars so that there was no possiblity of generating invalid keys, but it still got rejected. |
| _ghandi_ 20. Apr 2010 | I'll eat humble pie, just tested the keygenme and it actually only accepts 21 'D' chars so my keygen is still invalid because it accepts 22 chars. Don't i feel like a complete douchebag? |
| The-God-of-all 20. Apr 2010 | I have uploaded a corrected Version of my Keygen... I hadn't recognised the problem with the GUI, I watched only the code and there are 24 Characters allowed. |
| Trevil Author 26. Apr 2010 | Really glad you guys like the keygenme. It was supposed to be a trial keygeme for fhcf a few years ago, :) |
