| str_2006 10. Jan 2007 | Use 512 key lenght :d. Nice. |

| l0calh0st Author 21. Jan 2007 | Either it's too hard or too boring :P....Nobody solved it yet...I thought it would be broken within a day.....str have you solved ??? |
| jB_ 21. Jan 2007 | A sooo classic crypto-keygenme. I guess several people solved it, but didn't upload a solution. Might be good for people who want to start crypto. This is the step just after your first RSA :) |
| jB_ 21. Jan 2007 | Btw the keygenme is full of bugs, overflows and so on. How did you put so many bugs in so few lines of code? |
| Ox87k 21. Jan 2007 | i have problem with aes encrypt/decrypt so... i'm waiting for someone who upload a solution.. the rest of crackme is simply as jB told us. jB, did u solve it? |
| jB_ 21. Jan 2007 | Ox87k : yes I solved it, but I won't upload a solution except if there is no solution before a while. You recognized AES, what is the problem with the encryption / decryption? ECB mode is used, now you know what to do, isn't it? :) The biggest part in the keygen is to get a correct name buffer which, once encrypted, doesn't contain any 0 (I guess it was not wanted by the author, but using lstrlen wasn't really a good idea). Several names don't have a serial. l0calh0st : don't be offensed by my comments, they come from someone who coded 3 keygenmes in 4 years :p |
| l0calh0st Author 22. Jan 2007 | I m not offensed at all jB.....Infact thanks for mentioning it....I m still learning the stuff....I hope next one will be something different and of course with less bugs (Can't give guarantee for completely bug free though :P)... |
| Guetta 22. Jan 2007 | Solved ! Thx jB for the little help =) I'll write a solution if I found some time... |
| Ox87k 22. Jan 2007 | need some solutions :) |
| HMX0101 22. Jan 2007 | I understand RSA part but AES... i'm little bit crazy with that one =) Guetta... plz write it and good job :) |
| Guetta 23. Jan 2007 | I thought I've solved it, but I have a problem, the first AES part is working, but the RSA powmod give me some f*cking results... I'm trying to correct that and write a tute if I can. |
| Guetta 23. Jan 2007 | Okay, my problem was not a problem but a bug, btw i'll try to found a name without bug and write a tute. |
| jB_ 23. Jan 2007 | Serials can be found for any name not too long. It's not a bug, it's a feature. |
| hound 02. Mar 2007 | Hmm this one is too hard for me.... I know what I need to do, but just can't go about doing it :<, and Ive spent soooooooo long looking through each of those functions I assume is now part of BigLib :(. |
