| Crosys Author 27. May 2007 | So anyone tried it? |
|---|---|
| Guetta 27. May 2007 | Yes, I'm actually working on it =) Dunno if I'll find solution but this one is interesting, thx bro ! |
| HMX0101 27. May 2007 | Mate, good work! But it have a bug... if you see ElGamal isn't necessary to get a valid serial for second part because last comparation is after second '-' and if this piece of serial is right return 1 and give Success! |
| Crosys Author 27. May 2007 | yeah, really sorry about it, its fixed |
| waganono 29. May 2007 | Very nice job! It's a pleasure to solve it. I have sent my solution to your @. |
| HMX0101 29. May 2007 | waganono: are you going to write a tutorial?... it would be nice for all starter with elgamal :/ I've solved first serial, but second serial can't understand that thingy :( |
| waganono 30. May 2007 | Yes i'll write one, just wait a bit less than 1 week, i have a lot of work. The elgamal scheme (generally) is not so easy to understand like RSA, i think. |
| boonz 30. May 2007 | @HMX0101: If you need a tool for solving the DLP see hxxp://www.alpertron.com.ar/DILOG.HTM . It's very fast but don't forget to add 1 to your (p-1) so it's p! |
| HMX0101 30. May 2007 | @boonz: that's only i can do with elgamal :P @waganono: thanx i will be waiting for it :) |
