This challenge is awesome, it made me learn a new programming language, cause i got to make some research and wrote an decrypting program in python!!!

fun one!
did this one by hand (with some exel help of course).
Great instruction on the encryption theory here:

Finally got this one done. If anyone is struggling, I wrote a nice plunker with thorough code comments about the how and why I did certain things. While it is a spoiler, the code and comments show the how and my thought process instead of just the answer. Pm me if you're interested in checking it out.

I have looked through some of pythons docs, and learned a few new functions etc, but I am still not getting what I want. I've made lists and arrays from the encrypted message, but what i'm trying to do is sort the numbers into groups of three, then add them etc... I am fairly new to python by the way. Should I keep on going through pythons documentation?

DrosoFray, there is a full explanation on a previous page that you should read if you want to learn more about the algorithm etc. Here it is: viewtopic.php?f=28&t=954

The tricky part, in my opinion, is creating a script that will decode the message to the original characters, especially if your programming skills aren't that great, like me. I have been stuck on this level for weeks now, even though I understand how the algorithm works.

This challenge is broken.

When the mission page has already given the encryption algorithm, my first instinct was to google "XECryption algorithm decrypter", of course, it turned out to be a proprietary encryption scheme by you guys and google literally told me the answer to the mission.

I want to learn how to do this the hard/manual way so that I can learn something. How should I go about this?

I suppose the best way is to learn from a guided spoiler example that can be found on the net. Unfortunately for this particular challenge.

I find it stupid that I have to send messages to forum to solve this level... Well here goes then...
EDIT: PM system says no user exist with that username... Borken?
EDIT2: Okay, solved it. Use HTS messages instead of private messages
