Well, there is this encryption algorithm, which you need to understand. It is very easy. Just try to encrypt something very simpel like 'aaaaaaaaa' or 'bbbbbbbbbbb'. I think you should already see patterns emerging. Now you know the algorithm and the encrypted password, so the original password should be a piece of cake.

Yes, you must find the encryption pattern.


Edit: I won't warn you again since I did it just a few minutes ago. But again, please do not tell users directly what to do or give away hints that give away the whole mission.

Obviously, this mission is very easy. You don't even need a pen and paper. Just need ASCII table.
However, I recommend you people to try accomplishing it with a program. It will be good practice and learn things out. Even if you understand this mission, what you need to do, it will be like cake to write a program. It is not necessary to write a program, actually this is for those people who are to learn, not to just accomplish the mission and ran over to points.

Thank you, your hint helped me to start and finish!
If you could make me in the same way with mission 5...

ASCII tables should help you.

If you do this by hand (or thought), you'll probably need an ascii table for the "harder" characters...

I just spent like 5 minutes unencrypting that through almost completely trial and error. Was there an easier way to do it?
