Looks like a serial key to me.

Put it in Steam and see if it's viral marketing for a game.  Cheesy

That is very very obvious. Breaking a true OTP encrypted message is mathematically impossible no matter how much computer effort you throw at it.

One time pads are similar to XORing a pre agreed random text with your message text to create cipher text.
If you do not have the pre agreed random text they are unbreakable.

Given some one time pad cipher text you can 'decode' it to any message you like of the same length by preparing the random text to XOR it with.

According to Wikipedia they were known about in 1882 so would have been in common use in WWII.

Why can't anyone break this code?  they claim it might have involved a "one time pad"

uh... can't we super-compute the code on out of there real quick?

would be cool if bitcoiners did it... would get the community very positive attention.  Preferably a female cryptographer or a young kid.  That would be perfect for the media. We just *have* to have bad-ass cryptography experts combing these forums... (I am not one of them)
