| jB_ 05. Oct 2005 | I guess you have to code it yourself :p |
| Grivier 07. Oct 2005 | I tried this one,but it's piwing me off,i found that i need to code an dll that will start it. anybody has a clue where to find functions, |
| mips Author 30. Oct 2005 | I see that it's hard for the ones who don't have alott exp. look for something at: http://mathworld.wolfram.com/LaplaceTransform.html if it's too big hint delete this tread mips |
| jB_ 30. Oct 2005 | First part solved, but I had some difficulties (and actually no available time) with the last part. I'll look at it next week. |
| SatUrN 03. Nov 2005 | I solved the first part too. I've coded the lib but at the moment it's empty. Maybe with the hint I can continue. SatUrN |
| jB_ 05. Nov 2005 | "Maybe with the hint I can continue." The hint *is* for the first part... |
| scherzo 26. May 2006 | Hi mips! This is a very nice crackme. But I don't know if there is a bug or I need a hint... I'll explain: - at 004035A0 you do ESI = 0 - at 00403661 you do DEC ESI (ESI = 0xFFFFFFFF) - at 0040369E always this jump (jb 004035D1) doesn't occur because ESI(0xFFFFFFFF) > EAX. But I need ESI < EAX to complete the key in 00405268 (I already decrypt the key in 405268) using the code in 00403689. Please, tell me something. Thanks, scherzo |
| ksydfius 09. Nov 2013 | 8 years later, here goes a hint for the last part: think bigger additional notes: 1. the laplace hint is *ONLY* for the first part 2. jB_ is correct, you need to code DLL yourself 3. if memory serves me correctly, scherzo's point should be worth looking into 4. i dont remember finding any bugs 5. for your motivation, i know someone who had this done in about a week the rest is up to (maybe a lot of) maths, analysis, and some ingenuity mips and mods: please delete this post if it contains too much info thanks mips for the fun, i like it |
| h4rdc0re 02. Aug 2015 | 10 years and there isn't any solution yet... WTF?!! |
