My next release will be harder. It will be a while though because I haven't taken data structures yet. Again, after you get past the protection you should be home free.

Excuse me Ox87k could you make a solution explaining what have you done? I can't understand the crackme.
I saw other crackme written in java but the solution are difficult to undertand becouse i know approximactly nothing about Java. Thank you.

Great job man, keep the solutions(keygens) out of the comments though so more people can learn.

TIP FOR EVERYONE: The algoritm is as basic as it gets. Concentrate on getting through the obfuscation then the algorithm will be a sinch.

Dont give up costy, java is a doll once you get to know her ;-)

solved.

@CRY971C

I know this doll well, for I have to deal with her within my studies...and I´d be happier if I hadn´t to.
She owns long big teeth, yellow eyes and a devil´s smile...and she never heard about .exe-files.

For personal painful reasons, I won´t write a solution :D ... I hope Ox87k will.

@misunderstood

You must be CompSci/SoftEng too eh?

I guess it just goes to personnel opinion but I love java because if a system can run the JRE it can run java apps.

This mean linux, osx(?) even mobile devices. It just seems harder to do cross platform compatibility with the windows API.

@CRY971C

Yes, I am :). A lot of my fellow students love that language, and of course it has its adavantages.
Your point with the cross platform compatibility is a good example.

Anyway, as you said, it´s also a matter of personal taste and feeling...I just don´t like the feeling of coding in Java, for it´s a very strict/formal language (and not particularly suitable for the fast solution of problems, I think).

Call me crazy, but it seems while coding, I just "don´t get through to her" :D. It´s like staying at the surface, while coding in C or even asm goes beneath it.
Just my own experiences :)

I may have found a glitch... there is a name that allows you to write whatever serial you'd like.

EDIT: The serial has to be the same as the name

There is a serial that allows whatever name

As long as it's 4 chars

I may have a glitch... I found a name where whatever you type as serial you've still completed it
