The task is not impossible, I have calculated the number of possible permutations based on what I know about the password. I have looked at the power of current supercomputers, Tianhe2 could crack the wallet in less than a second. So hammering it with a computing cluster for a few hours or days should be able to handle it.
Don't how much computation Power I have right now. But I would like to give it a try for sure if you think the first half is correct and we only need to find the second half. Let me tell you I can't go above 22 Million possibilities but I still want to try.
Thanks
There is no point you trying, 22M combinations is orders of magnitude to low.
How do you know if they do not get everything?
And finding a complex password in an online service like blockchain.info is impossible, in my humble opinion.
Your task is impossible
There are ways to recover the wallet for an offline attack. I still have access to the email.
I think if they would be able to get access of your account then they would take it for them selves than take the $4,000 reward. Also what is stopping them from taking the whole thing and forget about you, right?
Well, I do hope you meet a whitehat around here and be able to get back that wallet. Good luck.
That's why I'm only going to use somebody extremely trusted, somebody who 3.5BTC isn't a lot of money for.
