| TripleTordo 14. Jul 2009 | hey, self-keygen made in less than 1 minute :) |
| WarRock 14. Jul 2009 | this keygenme is open-source hahhaha :D |
| CesNew 14. Jul 2009 | mmm i haven't read about DES algorithm... i'll try |
| TripleTordo 14. Jul 2009 | Yea xD, funny. only change message with the correct serial, but this is not the way :P |
| CesNew 15. Jul 2009 | lol ... like i said, 1st we must know how DES works xD |
| skNiNe9 Author 15. Jul 2009 | :D yea it's very easy, but there's no solution atm ^^ |
| obnoxious 16. Jul 2009 | I assume it implements Cipher.init("DES/ECB/NoPadding"); you are not using any padding right? tell me if this works. Name: F48A6B0BA44C72E7 (in hex) Serial: 1 2 3 4 5 6 7 8 |
| obnoxious 16. Jul 2009 | Sorry Serial: 1 2 3 4 5 1 2 3 |
| KernelJ 17. Jul 2009 | I tried writing a tutorial for this using jdb, and no matter how hard I tried I couldn't get it to do anything useful. It maybe works to a limited extent if the source code is available and the class was compiled with the -g switch. If anyone knows a way of using it which actually tells you anything please inform me... |
| skNiNe9 Author 17. Jul 2009 | what works to a limited extend? I wrote a keygen for my crackme myself and it works wonderful ^^ |
| KernelJ 17. Jul 2009 | I was referring to the JDB tool being a useless piece of crap. If I just wanted to solve the keygenme I would've just used JAD and adapted the output into usable keygen code. |
