Hey guys, Glad to see you all are enjoying the mission. I was the one who developed this mission and while I did so I was not sure how the users would like this sort of mission.

Vivekn: My only suggestion is to read the other posts.
A+, Network+, MCTS(70-620), Security+, CCNA

Just wondering if the decoded string should be just numbers and letters. i seem to extract the shift right and the numbers but the decoded string isnt always just alphanumeric

I am getting the correct solution. Submitting the answer always returns: Sorry, your answer is wrong.

Example:
hash: 93%99%105%88%117%83%
shift: 28
solution: AGM<Y7

Actual post that was submitted and received by the server:
[solution] => AGM<Y7

Result:
Sorry:
Your answer is wrong

I am using Java to complete this. I am submitting my result using:
PostMethod of apache commons httpclient.

I have also tried using HttpURLConnection and posting the data using a DataOutputStream and using the post method to write the answer to the server.

WTF is up? Is there a specific charset that must be used in order to get this to work?

Yes BhaaL - the answer is correct. This has been verified by developers.

93%99%105%88%117%83% <-- 6 shifted characters
AGM<Y7 <---- 7 characters

Developers have mistaked. Be sure, your answer is not correct. If it would be correct, the site cant tell you that it is wrong ;)

to anyone who might be stuck but not sure why, make sure that you reverse the shift, ie:
shift: 1 means shift everything by -1

That was the easiest of the programming missions in my opinion. It only took me apache + a few lines of PHP.

Python + curl (pycurl) ftw. It took me a bit to realize that you needed to keep the cookie to post data. Other than that cool mission!
