downloadprout's The thing

Download thething.tar.gz, 5 kb

This is a simple command line app which asks for a name and a serial.
The difficulty is not really on the algo but is where is the algo...

Just write a keygen for this...

I have a box that is running glibc 2.3.6 and I think this is compiled for 2.4...any chance you have a box with an older glibc you can compile this on?
09. Mar 2007
Ok, you are not the first who tells me about that :-(
So, please wait a little while I check on my old Linux distros and reinstall it. I will soon deliver you a more portable version...

Thanks for your report...

Thanks! I haven't been able to run it yet but what you do with the virtual address mapping is very nice! :D

It should be ok now. I compiled it under Slackware 11.0 which uses glibc 2.3.6.
Tell me if you have any trouble with this version...

I don't have much time today to look at it but I did test it and it seemed to run fine on my debian machine!! Thx! :D

Solution submitted. You method is quicker than parsing the ELF header. neat!
21. Mar 2007
Good work Macabre. It was my first keygen, and I don't know how to strip an elf, so I modified the elf header with an hexeditor to hide section headers...
Since I'm a beginner, I found your solution very interesting.
And in fact, since ald seems not to be maintained for two years I didn't think to use it before.

See you soon here, I hope... :-)

There are a couple of things for elf headers. sstrip comes with elf kickers and Elfsh has a method as well. Elfsh is probably best. I didn't use to use ALD until I saw crp- here use it on one of his solutions ;) I'm glad you liked my solution! :D

Ok thank you.
Actually what elfsh can't do... :-)
