This challenge was planned to get released on net-force, but it seems to take ages to get it released there.
So I decided to put it online on wechall.
Thanks go out to Jander for testing the challenge!

And here is your mission:

Oh look, a file encrypted with a one time pad xor cipher.
I am sure you can figure out the key in a logical manner.

Original File Type: ZIP Archive (MAGIC DWORD 0x504B0304)
Type of Encryption: XOR One-Time-Pad

download the encrypted file

Enjoy!
