Topic: I need help to import my wallet, please help me ! (Read 190 times)

Bitcoin-qt's private keys aren't based from your wallet's password, those were randomly generated.

Plus there's no other backup method aside from dumpprivkey (not natively available in 2010 but can be done using wallet tools) or a copy of the wallet.dat itself.
If you can't find any of those backup, your coins outside of MtGox is out of the question.

What I thought which I replied to, but he later made it clearer that he bought 165,000 BTC, he withdrew 110,000. Which means he has some coins on the exchange which he also asked for how to recover it back. So the question is about the coins he has on an exchange and the ones he moved to wallet.

He did move his coins from Mt.Gox to an unnamed wallet (yet) and wrote down the private key physically in a notebook. That notebook was stored in a safe, but the content was somehow destroyed by water. The assumption is that it's totally gone and beyond saving.   

Not anymore. In the meantime we found out that his mom got rid of his old computer and surely the hard drive with it and threw everything into the trash. There is nothing to get the data from anymore unless he goes rummaging through local landfills in search for his old computer.

That's not OP's "best chance". It's ONLY chance, and services for recovering lost data from corrupted hard drives is not hard to find anymore.

OP, I don't know about CMAC, or any other application that generates/outputs private keys by using public keys as inputs. If there was such a program that works, the developers would never upload it, but use it to "mine" for Satoshi's wallet's private key.

Jokes aside, personally get the old hard drive, then look for a data recovery service.

In addition, if you buy coin on an exchange, know that it is not a wallet but an exchange, just move your coins that you bought on the exchange to a noncustodial wallet, if the amount is a large sum of money, make use of a cold storage instead, or get yourself a hardware wallet. Exchanges are often hacked and anything can go wrong just like what recently happened to FTX. Also backup your seed phrase like in two or three different locations that is safe from damages and attacks.

As far as I know, Mt.Gox is no longer accepting requests for compensation and they are now supposedly in the process of final preparations for payouts. Maybe there is another way that I don't know about, but it seems to me that Mt.Gox is a dead end and a done deal.

If the computer ended up in the trash together with the hard drive on which the wallet files were located, then you have nothing, and no passwords or anything else will help you. If by any chance you have that hard drive, then you can try to save the data, and whether you want to do it yourself or seek the help of professionals who deal with it is something you have to decide.

Edit the whole first post because too much information is missing or doesn't make sense and start from the beginning.

Did you buy bitcoin somewhere else and sent those coins to Mt.Gox? Or was the purchase completed over the exchange and the coins never left Mt.Gox? What did you invest in Mt.Gox?

That means nothing if the coins were at an exchange.

Private keys of what? Were your coins ever withdrawn from Mt.Gox, and if so, where did you send them?

Passwords of what?

Importing an address won't allow you to spend the coins from it. The transaction needs to be signed, and it gets signed with the private key.

Edit: You posted while I was creating this post.

Is the damage to the notebook beyond recovery? Can you read none/some/most of the characters of the private key?

Your mother threw the computer away and you no longer have it. Since there is no computer, there is no wallet or wallet file either. You probably have the decryption password to the wallet file, but without the file it's useless. It would be like if you had a key to a house that got completely destroyed in a fire and doesn't exist anymore. You can't do much with it.

I am afraid the coins in your private wallet are lost and are beyond recovery. You might have more luck with the BTC that were left in your Mt.Gox account when the exchange got rekt. But you need to prove the account belongs to you, and I am not sure if you can do that.

Here are a few sources, maybe they can help you in the right direction:

I bought all my Bitcoin from the mtgox total 165,000 and withdrawn 110,000 in my personal computer. First my computer crashed in July 2013. I saved my private keys in a diary but that diary got damaged and my rest of the Bitcoins was in the mtgox. Then I lost the access to the mtgox. All my savings I lost. I was not a technical person.
I was a University student when I bought those Bitcoin. My parents tried to stop me but I did not listen to them. I have my wallets password of my computer. But my broken computer  was in my family house and mum puts in the computer in  dustbin. I hand no idea that I could have restore the data from the hard drive. I now live in abroad. I don't know how to import my wallet in my new computer.

Also I need help to see if I can get some Bitcoin back from the mtgox.

Can't understand what you are saying.

1. If you bought bitcoin and then moved it all to Mt.gox then you should find out about Mt.gox death because it crashed in 2014, they are now announcing they will return bitcoins to that year's victims, you should contact them directly for more details.

2. If you bought bitcoins on Mt.gox and transferred them to your personal wallet and you lost your private key. My condolences to you, there will be no way to get your 16500bitcoins back, without any chance unless you're lucky enough to have another copy of your private key, try rummaging through your brain.

It's not 100% clear what you've done, I will assume you withdrew your coins from MtGox to your wallet and exported the private key.

* I remember that certain wallets (Multibit?) were allowing to export the private key password protected. If that's the case you need both the encrypted private key and the password.
* A crashed computer has in most cases a recoverable HDD. If that's the case you may be able to recover the wallet file. That may also be password protected.

However, recovering the private key from a password is most probably impossible. The only case it would be possible would be that it was a brain wallet built from that password (is that the case? do you remember how you created the wallet, was it you from some words, or it was the wallet software doing it at start?), but if that's the case probably it was already found out and stolen, especially if the password was dictionary word.

I think that your best chance may be to get the data recovered from the old HDD.

You have password of what? Mtgox? If so, you can't get anything from that as you know what happened with mtgox.
In case, you have password of your bitcoin wallet from your computer, you must have the wallet file. If you don't have it (you said your computer crashed), you won't be able to recover the wallet file. If you the hard disk from your old computer, you can try with any reputed data recovery service to get your wallet file.

You bought bitcoin from an exchange and moved it to your wallet? You need your private key to access it. Only what password can do is to access the wallet you created on a device, the password remain to that wallet on the device. If the wallet is deleted or the device is changed, you will set a new password and the old password becomes useless when importing the private key. Only private key can be used, that is why you supposed to backup the private key. You can not generate private from password.

I bought 165000 Bitcoin in 2010. I invested it in the mtgox. My computer crashed in 2013. I was not worried as I had my private keys in a safe but my written paper notebook ruined and cannot read my private keys. I have found my main passwords. How can  I use my passwords to get back my private keys?  I have heard that it is possible to use other programms like CMac to generate private key to import the wallet or Bitcoin address. Please help me out to import my Bitcoin address into my new computer. I am willing to pay out reward who can help me. Please help me.
