Brainwallets how to use?

[Nobitcoin]

I was wondering how to use in my bitcoin app when I got a private key and an address... Maybe get a different client?

I do not understand?

Topic you gave is: Brainwallets how to use?

so far as I know

A brainwallet refers to the concept of storing Bitcoins in one's own mind by memorization of a passphrase. As long as the passphrase is not recorded anywhere, the Bitcoins can be thought of as existing nowhere except in the mind of the holder. If a brainwallet is forgotten or the person dies or is permanently incapacitated, the Bitcoins are lost forever.

I am asking because I do not understand the thread - what have a client to do with a brainwallet?

He's trying to import the private key into his mobile app. Now as far as I know it works with the standard PC core version, but not on mobile phones.

Sure you can import ... you can import private key into mobile Bitcoin Wallet for Android - if this is in this case.

Maybe OP will explain it better to us.

A brainwallet is a great way to have your bitcoins stolen.

You better be really sure that you understand all the risks and exactly what you need to do to generate a secure brainwallet before you start receiving bitcoins that way, or you'll be rather unhappy.

Well when I created a brainwallet I was given a wallet address and private key... Just wondered how to import them both into my wallet

Typically, you type your passphrase into a brain wallet site and it will give you the private key. Then you import that private key into your wallet. The bitcoin address is derived from the private key, so the imported address should match yours.

Thats only if his coins aren't already stolen. I've seen brainwallets get emptied within 10 seconds.

How so?  Not enough entropy? Or are there other pitfalls?

That's the main problem. Humans aren't random enough to produce a string of words that have enough entropy not to be brute forced by a computer. So mostly any funds placed in a brain wallet are taken nearly instantaneously by someone who has simply brute forced their way to private key.

Often a brain wallet passphrase is the first line of a book, or a few words from a popular song, and so on. Anyone can generate addresses from hundreds of songs, popular books, etc, and regularly verify if anyone else has generated the same address and deposited some bitcoins.. et voila', your bitcoins are gone!

Which wallet are you using? Bitcoin Core? Blockchain.info wallet?
If you are using Bitcoin Core, you should use "importprivkey" command at the Bitcoin Core debug console.
For details, google it.

DannyHamilton is right. I would not recommend anyone to use brainwallets.

In it's current form, yeah- but it would be easy for this to be fixed (Why hasn't someone already?) For example you could pick a number and use it anywhere in your brain wallet and that could be the number of times the passphrase is hashed to give you your private key.

The number should be high ... preferably in the order of billions.
