| Kerberos 09. Jan 2006 | Ank83: java -jar CM1.jar |
| Ank83 09. Jan 2006 | damn ! I dont have JAVA on this machine ! Hm I think that DJ Java Decomipler will be of a big use for this crackme ! |
| Ank83 09. Jan 2006 | I always get this ! java.util.zip.ZipException: The system cannot find the file specified at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.<init>(ZipFile.java:112) at java.util.jar.JarFile.<init>(JarFile.java:117) at java.util.jar.JarFile.<init>(JarFile.java:55) Exception in thread "main" |
| Ank83 09. Jan 2006 | Can anybody help me ! Is the problem with me or the app !? |
| Ank83 09. Jan 2006 | aldo it give to me when i try to run it: ava.lang.Error: Do not use CM1.setLayout() use CM1.getContentPane().setLayout() instead at javax.swing.JFrame.createRootPaneException(JFrame.java:458) at javax.swing.JFrame.setLayout(JFrame.java:524) at CM1.<init>(IYOE) at CM1.main(IYOE) Exception in thread "main" |
| HMX0101 09. Jan 2006 | install the most newly version of Java 2 Runtime :) |
| Ank83 09. Jan 2006 | Hm... Finally !!! I start it ! Yeeeeeah ! Like first you need to extract the jar file (I used WinRar), load the CM1.class in DJ JAVA Decompiler, find the line: setLayout(null); and insted of that write: getContentPane().setLayout(null); Than save the file as CM1.java, then compile it and then you can run it ! I don't know i this is a bug, but on my machine IT WAS ! So i needed tochange all that so I can run this crackme ! P.S. When you load the crackme in the decomplier, you'll get all you need to write a keygen ! I will start writing it as soon as posible ! Now I'm going to sleep a little bit ! And tomorow I'm taking my wife to diner ! :D P.S. Nice crackme ! A little change won't hurt anyone ! :) Regards Ank83 |
| vhly Author 11. Jan 2006 | I use the JDk 1.5 compile this crackme And Use the JShrink 2.36 obfuscate this; I think that you should install tht JDK/JRE 1.5 If this can not run yet, please mail me. |
| m@[tador] 12. Jan 2006 | It normally works on JRE 1.2 if you replace setLayout(null) to getContentPane().setLayout(null), like Ank83 said. And I couldn't find any obfuscated code. Maybe your obfuscator don't works properly? I posted my solution, written on Java (for JRE 1.2). The algo is wery easy. Serial is the Name in base64 encoding. |
| vhly Author 13. Jan 2006 | So I say this is Very EasY. Only BASE64 Encoding |
| Wolle 21. May 2006 | Hey all, im new to all this, but i anyway succeded to crack the serials :) So now i have made my first KeyGen, i love it! :D |
