Hey, it works... thank u sooooooooooo much. U dunno how immensely helpful this encryption-decryption knowledge is going to be for my nxt development Wink

Does anyone know where do i get the algo/code for this encode/decode ?

You are welcome.
I guess this post would be helpful to you. https://bitcointalksearch.org/topic/m.1185413

Better to just print out a cold wallet.

I guess you meant paper wallet

There's no reason to figure out how to spend a brainwallet, they'll be gone before you even query blockchain.info to watch your deposit.

Why so ?

So, pretend Edith Bunker or Rose Nylund, or Anna Nichole Smith or Jessica Simpson or Ann Coulter or Sarah Palin or Kim Kardashian or Honey Boo Boo wants to start buying bitcoin...

I'm pretty sure Kardashian and Honey Boo Boo aren't allowed any, I saw it hard coded in there somewhere Wink

I can tell already, this isn't going to go well.

Messing around with raw transactions and trying to encode your own transactions when you don't have the initiative to figure some of these concepts out on your own is a great recipe for losing bitcoins. Hopefully nobody else will give you control of their bitcoins, so the worst you can do is damage yourself.

You could push it to Eligius as well.

hey, thank u so much...

I was just trying to decode a Tx through https://blockchain.info/decode-tx.

I tried to decode 16c9fc140bae884180d0fdc7a469ffe30f73dc3f3630970adf206d6456dccaca

The result is Parse: Error Parsing Transaction

Am I doing something wrong ?

"16c9fc140bae884180d0fdc7a469ffe30f73dc3f3630970adf206d6456dccaca" is the Transaction ID indeed.

You can get the raw transaction of that tx in the following page.
https://blockchain.info/tx/16c9fc140bae884180d0fdc7a469ffe30f73dc3f3630970adf206d6456dccaca?format=hex

You should get the following:

How exactly is mainstream public supposed to feel excited about bitcoin when they get handed this kind of information from tech and dev nerds on how to secure their money?

Mainstream public is used to "here's my card/scan/receipt/done" and an online account they can keep up with their purchase and balance...and a password...and somebody else to make sure their stuff is secure.

Downloading stuff and all this encryption and python talk isn't going to help BTC win popularity points. That is over the head of most of mainstream.

So, pretend Edith Bunker or Rose Nylund, or Anna Nichole Smith or Jessica Simpson or Ann Coulter or Sarah Palin or Kim Kardashian or Honey Boo Boo wants to start buying bitcoin...

Please share how you'd explain bitcoin and how to use it with them because that's about the mentality level of the ones who will make or break btc becoming a long term "thing" in life.

How would you handle it?

For them, we have it...

... how do I spend them without using any client ? I mean how the whole system of Brainwallet works ? I'm confused. Can anyone please shed some light ?

Though people here have demonstrated how to send transactions manually, that is not the best use of a brain wallet and it is certainly not practical.

The typical use of a brain wallet is as cold storage, just like a paper wallet. Typically, when you want to spend the bitcoins in the brain wallet, you would import the private key into a normal wallet.

Regardless, a brain wallet has a high risk of being cracked, so I don't recommend using one.

But, the blockchain.info wallet address is also generated from a passphrase... is not it ? In that case it is machine generated and in this case it is human generated. So, if I right something meaningless (example below) and create a wallet from it ...will it really be insecure ?

Example Passphrase: asdsd fkkksdhj kdddf kdkaskda asdssak

Also, at brainwallet.org I see they are adding something called Secret Exponent. What is that ?

When you want to spend your coins, you can sign your transaction with the private key, or simply import the private key to a wallet.

Cant you do the same in blockchain? I seen people sign per transaction id with a message.

I think u r referring to blockchain.info. Yes, you may import the private key over there in your wallet. But blockhain.info messages with Tx are different than this. That is just an added feature by them where the messages are fetched from their own DB.

Thank you for your response. Sorry, I did not understand the first part. Without a wallet, how do I sign my transaction with the private key ? I mean, without a wallet, resident or on the web, how do I make a transaction in the first place ?

Here is a detailed walkthrough.

You can just broadcast the raw transaction on https://blockchain.info/pushtx afterwards.
