What is wrong with the linked file? Can you find the correct code?
Link: file
Post here the correct answer, and how you discovered it.
I should mention it is puzzle based.
Have fun!

30f3845a5c909da91ed9be14c8fb3fdaThe downloaded file is a tar file. The nine graphic snippets need a little modification using ones favorite graphic editor and joining them to a new graphic that is a proper QR code. I used bcTester to decode it.

First, use linux file command to find out what type of file it is.
On windows, I do not know, maybe there are alternatives.

When I had decoded the QR code, I thought it probably is the hash of a cddb/freedb entry since there were also lyrics in the tar file. I just had time to check this. If there is a further step beyond the posted solution, cddb/freedb is a dead end. Their hashes are much shorter.I still don't know if this is the final password, or images names are hashes that should be brute forced. Or, more plausible, the found key is a md5 hash that holds the password. This is something I do not know, because the challenge is not made by me.

We are trying to arrange something................. And I think it is too late to verify it.
dCTF 2011, Challenge #1Do you have any idea where I got this challenge from? Any of you?

Probably it's an indicator where to put the pieces of the puzzle (although that's not difficult). Or it is meant to confuse peopleone more unusual thing , all the puzzle(.png) files have md5 length names....
but they are not md5 hashes

30f3845a5c909da91ed9be14c8fb3fdaThis looks like a MD5 and it is being decoded as we speak here
