I thought I might be able to help out a little bit here... To download the (encrypted) wallet from blockchain.info, run this from the command line (Linux or Windows, but for Windows you need to install Python 2.x first). python -c "import urllib2,json;f=urllib2.urlopen('https://blockchain.info/wallet/9bb4c672-563e-4806-9012-a3e8f86a0eca?format=json');print json.loads(f.read())['payload']" > wallet.json.aes(Obviously you'll need to change the UUID to match yours first.) Thank you very much! This is very helpful For brute-forcing the password, I'd recommend one of two options. If the downloaded file doesn't start with these two characters: {" , and if you've created or modified (e.g. added new receiving addresses) to it at sometime after March, 2012 (when the wallet format changed again), and if you're on (or have easy access to) Linux and are comfortable compiling software, then I'd recommend John the Ripper ("bleeding-jumbo" version). It's faster than the alternative (and much faster with a GPU). Otherwise, I'd recommend btcrecover (course I'm biased since I'm the dev of that one...). It supports some blockchain.info wallet formats that JtR doesn't, and it's easier to set up (no compilation necessary), especially on Windows. The Quick Start is available here: https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial. Let me know if you have any questions about it... I will go for John the Ripper first. I'm on linux as well as windows. I don't have much compilation experience but I did it a few times in the past. Last time I had to do it with vanitygen which worked out well. Otherwise I will try the btcrecover method. Thank you very much for your help, I hope I'm able to recover the wallet. I asked my friend if there is a bounty, if so, you'll get 50% of my bounty if I'm successful  |

The wallet is probably somewhere hidden in these lines of code <script type="text/javascript" src="/Resources/wallet/bitcoinjs.min.js?sdffsdfdsfssd"></script>
<script type="text/javascript" src="/Resources/wallet/blockchainapi.min.js?dsgsdgsdgfsd"></script>
<script type="text/javascript" src="/Resources/wallet/wallet.min.js?4b4sdgsgdsgfs"></script> |

If so, knowing the public key as well, I can try to brute force the password or am I missing something?
The wallet contains 0.22 BTC
To brute-force the password, you'll need to know as much as possible about what the password is likely to be. Then you'll need to use the identifier to get a copy of the encrypted wallet. Then you can attempt to decrypt the wallet with the various possible passwords until you find one that successfully decrypts it. Do you happen to know the encryption method used to encrypt the wallet? edit: it is aes, just found out. Where is the wallet stored when accessing the wallet through a browser in windows?
blockchain.info stores it in their database. They send a copy to your browser when you supply the identifier. So I fill in the identifier and look in my browser cache? edit: if I save the page, I see a lot of stuff, but not a file called "wallet.aes.json" Thanks for the detailed answer btw. |

The identifier is the filename of your wallet, your identifier do not change when you change your wallet password. The wallet file is encrypted with your password. You forget your password, you loose your coins. Blockchain.info can't reset it for you.
He has got an iphone. Where could the wallet be stored in an iphone? Where is the wallet stored when accessing the wallet through a browser in windows? I know blockchain can't reset the password. I'm looking for the wallet file. |

a friend of mine can't access his wallet anymore.
The passwords are not accepted. He probably forgot his password.
He probably used an easy password as well.
But he hasn't got a backup of the wallet, but he does have the identifier.
Does the identifier represent the encrypted private key?
If so, knowing the public key as well, I can try to brute force the password or am I missing something?
The wallet contains 0.22 BTC

Problems with btc:
1. wild, unstable exchange rate
2. difficulty to obtain and use (for most people)
3. getting coins hacked or lost by sending to wrong address
4. fraud/theft at exchanges (if it happened at Gox it could happen anywhere)
5. it enables criminals to get paid online
6. there are already plenty of ways to send money online a lot easier, it doesnt really do anything new
7. absolutely no buyer protection
8. scam companies/scammers
feel free to add to this list ^^
good things:
1. cheap way to send money
2. only 21 mil ever in circulation
So why should more people start using btc? It seems the cons outweigh the pros.
Always the same questions over and over and over and over and over again. This forum is bulging from all the answers too. If you don't like bitcoin, don't use it. |

Cut yourself loose people. I predicted this downfall days ago. Look at the date and chart. We are still heading down, but I think you should buy somewhere at the beginning of september. Don't worry people. Just hold tight!  1K9vcx2wAiS6gDeNZcjKfqJtZ7anYJWZe5 well your timing sucks You forgot the sarcasm tag. |

People, price is about to go moon.
I sold some at 298 and placed a buy order at 184.
Usually this means price will go up immediately.
People, I would like you to thank me. Thanks to me the price stopped getting lower. Right after the moment I sold the price went up. I do accept donations. Look at my profile page, the address it there. I could need a few satoshis to fix my loose Thank you anonymous donator! I love this scene... |

I like your idea. I don't think the protocol can accommodate this. But perhaps some kind of service that relays your spend, with a grace period before they broadcast it to the blockchain? I'd pay a tiny fee for that piece of mind. No matter how may times I buy stuff with BTC I still cringe a little when I hit the send button.
Amazed to see this reply from a legendary and foundation member... No offend. |

I am curious, how many of you make a living with Bitcoin daytrading / Stock trading?
I'm very happy to have another job. I would bankrupt myself if I did daytrading. I only experiment with 1% of my holdings. |

I changed my side bar because we are already passed sept 25th. It must happen before oct 25th. Top of the bubble will manifest between november 6th and november 20th. It is based on some interpolation. I hope I'm right  |

I'm a permabull experimenting with 2% of my stash. I noticed that I'm a terrible trader because now it's worth 1% of my stash  Luckily I'm too afraid to trade more and I'm a bag holder since $27 (2013). Usually I add to my position and buy the dips. I never bought higher than 550. I'm waiting for some moment in the future when I can pay off my house with 5 bitcoin. Edit: the sidebar information is based on some analytics where no emotion is involved. It is also an experiment. |

Dear coinbroker, thank you for your payment. It helps to earn some satoshis while the price is plummeting these days. |

I told you so. Price is jumping like a maniac! |

People act is if it's going to kill them if they have to hold an investment for two years. I let Vanguard convince me to hold on to GNMA securities for five years and only made 2.54%.
This. No-one ever lost money holding BTC for a year. I never lost any bitcoin (money). Anyone who takes care will never lose any of them. Just count the coins, they will not multiply or divide out of them self. |

5 days i checked the bitcoin cap was $5,070,314,778 and now it's $4,133,378,508  1 billion waiting to buy on the next big rally isn't a bad thing. It does NOT work like that. Market cap dropping by a billion does NOT create a billion to spend on bitcoin... Yes, and it is this reason why the price is falling. The noobs will sell at the bottom (My buy orders are at 184) edit: but don't listen to me, I'm a terrible trader I only trade with 2% of my stash, the rest is in cold storage out of reach. |
