Did you wait long enough? I suspect there a ^C that you didn't copy from your console.
Try again, but this time, grab a juice box and wait.
This is brute force, not magic.

Saying "not working" I mean - not working! :)

Chudnovskiy, you need to add "-m32" to the gcc lines in your Makefile. At this point you'll need to "make clean" to clear things out, make the change, and re-compile. I had the same issue you did when I tried to compile on a 64-bit system, but the program had worked for me on a 32-bit system previously. Adding the "-m32" lines worked for me.

yep, same problem as Chudnovskiy. And solution adding flag works at least for info. Waiting for decrypt my own file.
