Applied Cryptography Intro - Keygen ExeShield Yourself

Be ready... If I find something interesting we will meet again... Sadly, from october I won't have free time .
Please pay attention for the moment: I did a small (?) mistake within full txt tutorial (the one which describes how Registration # is calculated).
The mistake is: I've written that You've to replace nineth char (which isn't a dot). Of course I had in mind tenth char (which is a dot). Sorry.

So far I've seen this file being 77 times downloaded. I've reattached this one, so the counter has been reseted and You can download the attachment, which is now corrected.

Regards.
