CSCamp Crypto-PNG

Again i don't remember the exact question.
There is an encrypted image can you tell me what is the message?

When googled about it there was a similar question in some CTF and i found that xor cipher.So asked one of the admin and confirmed it.Now which tool do we use? Xortool from hellman.Astonishingly he himself was there in the irc :-p
Download it here : https://github.com/hellman/xortool

Go to the xortool and type this in command line "python ./xortool.py -c 00"
First time i used the tool and was totally impressed.

Key is : x0Rk3y
well i havent made the python xortool.py a executable.If you are using linux you can just run this command "chmod +x xortool.py" and after this you can just use xortool.
Now lets go ahead note that i haven't made my xortool.py a executable.
Lets run this command now enc.png python ./xortool.py/00_x0Rk3y
After this you would see a folder named "xortool_out" and in that a file named "0.out"
Rename it to .png and open it in paint or whichever image viewer you want.

you will see "The key is pwnthexorcrypto"
