I see it as well. Maybe I'll give it a go tonight if nobody else gets around to it.
Nevermind... found 0.10 BTC. Your urandom is certainly broken. It wasn't XOR'd at all... 
Topic: I have pasted my wallet.dat base64-encoded, crack it and the contents are yours - page 2. (Read 3442 times)

I guess the only thing i can think of is that urandom is not as good as random.
As in it might just use a seed number. Also he appears to have limited his characters to printable stuff?

It's base64 encoded silly.
Clue:
wallet.dat has structure and urandom is not truely random

There is a weakness in it, i'm not going to reveal it - want to see if anyone in this community spots it.
A professional cryptographer would spot it in seconds.

The file is just a PNG of some kind of masonic symbol.
With the right key of course it is
But that's not the point here

If that file you posted is XOR'd with data from /dev/urandom, I think your /dev/urandom is broken.
Do tell!
Have you found the weakness?

XOR one-time pad on linux using /dev/urandom
didn't even look at it, I pass
If I'm going to turn random data into a wallet, I'd rather turn it into the mybitcoin scammer's wallet. Then I'd have sooooo many coins.
(If you don't get how that makes logical sense go read up on OTPs...)

encrypted with an XOR one-time pad on linux using /dev/urandom:
No thanks.

Is that a "fuck it, i can't do this?" or a "fuck it, i'll crack it" ?
Its a Fuck I would rather get hit by another hurricane and lose power for 3-4 days then even try.

If someone cracks it, all I ask is you tell me how you did so.
