Also this link (https://blockchain.info/wallet/wallet-format) talks about this format - but again no way of importing it...

According to that link...

I have just a file named "Bitcoin Wallet private key backup" (555 bytes)
and it has

{"pbkdf2_iterations":5000,"version":2.0,"payload":"[here a lot of characters]"}

inside but it doesn't look hex or anything like that inside the [here a lot of characters] - just a lot of letters, digits, = characters, / characters and \ characters...

Any idea what it is?

Those "letters, digits, = characters, / characters and \ characters" are base64 digits. typically you also might see some + characters as well.

As mentioned in the link you provided...

the [here a lot of characters] is the base64 encoded AES encrypted JSON payload which contains the private keys. If you can remember or find your password, then you can use it to decrypt the payload with AES decryption. The decrypted payload should contiain your private keys that you can then import into some other wallet.

Blockchain.info changed to HD wallet last year. The 12 words is part of the HD wallet.

The blockchain.info page you linked actually says that you can import it to multibit. But If your private keys are encrypted, the only way to restore them is to use the password. So bruteforce is pretty much your only option.

Thanks. I see...
And how do I bruteforce it? Any idea?

Really appreciate your help,
Joanna.

If your password wasn't very long with many mix of keyboard shortcats than it won't take so long time. You need good pc and software which will do bruteforce of that password, also you can use wordlist for that if you have of course. Search more deeply in google about your private keys and use bruteforce in worst situation.

Check shorena's reply above. It'll direct you to a tutorial. Find "Quick Start" and follow the steps.
Bruteforcing can take forever if your password is complex and very long and you've forgotten all of it, btw.

THANKS for the reply again. I really appreciate it!!!

OLD?
Yes, this file is from March 2015.
And that is all I have apart from the wallet ID (and my e-mail address).
I have some mails with the transactions I did then and some transaction IDs (though these are open to everyone).

I don't even remember I had any of those 12 words that are used now. I don't think I had to do it back then.

Googling "bitcoin private key pbkdf2 iterations version 2.0 payload" -
I see this: http://bitcoin.stackexchange.com/questions/35914/blockchain-info-wallet-format
Saying something about the exact format that I have... but I don't see any way of importing it.

Also this link (https://blockchain.info/wallet/wallet-format) talks about this format - but again no way of importing it...

Is there any other option apart from Brute Force?
And you mean the brute force described in https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial
?

Sorry for million questions. I am really helpless - and would appreciate any help.

Regards, Joanna.

Thanks for the reply...
I tried all my usual passwords and none of the works but the wallet still exists.
I have just a file named "Bitcoin Wallet private key backup" (555 bytes)
and it has

{"pbkdf2_iterations":5000,"version":2.0,"payload":"[here a lot of characters]"}

inside but it doesn't look hex or anything like that inside the [here a lot of characters] - just a lot of letters, digits, = characters, / characters and \ characters...

Well those are not private keys. At least not importable unencrypted ones. You might have to brute force it after all.

But last I checked the ability to backup your wallet's private keys is gone since a year ago. If that file is old and you've used addresses generated by the new blockchain.info wallet recently then those private keys are probably empty.

Hi friends,

I lost my phone and had BlockChain on it.
I don't remember the blockchain.info password - but I do have the wallet ID + private key file.
The private key is really long and looks like:

{"pbkdf2_iterations":5000,"version":2.0,"payload":"[here a lot of characters]"}

Any idea how I can recover my account? I would be really grateful...

Regards, Joanna.

Blockchain.info can't help you with lost accounts so if you lost your password you lose your account. But if this "private key file" really have private keys (begins with 5/L/K) of your original addresses you can simply make another wallet and import them.

No I dont escrow anymore.

Do you remember at least a bit about your password? If so it might be possible to brute force the rest, using e.g. btcrecover[1].
