| InterGhost 01. Jun 2008 | It's the most interesting CrackMe I've ever seen =)) Thanks!! |

| Jim~ Author 02. Jun 2008 | Glad to hear you enjoy it. Any luck keygenning it? It's not too hard ;] |
| born2c0de 02. Jun 2008 | It looks like a one-way hash function although I could be wrong. Are you sure this can be done without bruteforcing? |
| Jim~ Author 02. Jun 2008 | Yep. I've already made a keygen myself. :) |
| born2c0de 02. Jun 2008 | Cool. In that case, I'll keep trying. |
| Jim~ Author 05. Jun 2008 | A few valid keys to help you along, maybe? User: JiM~ Key: QMbb8AYbMEVab4SZrsPY7QMYLUJXbIGWq8DV6 Key: FhtvwxhswBVpvRJmug9jtwxgtAldsQZargNXqwBU Key: h41iNwzgtYpfNAndsodcMQbar4RZLgPXrIFWKwDU :) |
| costy 05. Jun 2008 | first key doesn't work on my pc! |
| Jim~ Author 05. Jun 2008 | haha! you're right. I didn't copy the whole key. whoops! >.< |
| simonzack Moderator 06. Jun 2008 | I don't get it at all. My keygen sometimes works, sometimes doesn't, but Overloaded() and getHash from name is definitely equal I got another key for JiM~: wv7+/v7+/v7+/v7+/v7+/v7+/v7+/v7+/v7+/v7+ |
| simonzack Moderator 06. Jun 2008 | Sorry, dont know how to edit the gethash I get for "JiM~" is 207 ((name->GetHashCode()/0x186a0)%0xff) but i think it should be 163 |
| Jim~ Author 06. Jun 2008 | My guess as to why your keygen won't always work has to do with not compensating fully for the modulo inside overloaded(int[]) Just a guess. PM me your algo for generating and I'll take a look at it. Or maybe some of your 'should-work, but don't work' keys? |
| AloneInTheDark 07. Jul 2008 | Hi, I have send my solution. I have update Overloaded() function, my Overloaded() return "true" value. The password is any string of 40 characters. |
| Jim~ Author 09. Jul 2008 | AloneInTheDark: Based on your comments, it sounds like you patched or rewrote the Boolean Overloaded() method. If so, that won't be accepted as a valid solution here. The only valid solution should be a key generator. |
| obnoxious 21. Aug 2008 | Well Jim~ did you like it? :) |
| Jim~ Author 24. Aug 2008 | Nice work, obnoxious. I enjoyed reading your solution. You broke down my recursion haha :) |
| raygeee 10. Jan 2009 | Actually, to create a KeyGen it isn't really necessary to reverse the overloaded(string) and overloaded(int). overloaded(int[]) and overloaded() is enough. Just use the original methods to get the encrypted value of the name. One other thing I got into trouble was that I got a StackOverflowException when running in Debug mode. In Release mode the recursive calls run perfectly because of the optimization. However, I found that a really nice one! |
