Python Generate Private Key Bitcoin

admin

Recently, I became interested in the inner workings of Bitcoin – specifically, the way it uses elliptic curve cryptography to generate Bitcoin addresses such as 1PreshX6QrHmsWbSs8pHpz6kLRcj9kdPy6. It inspired me to write another obfuscatedPython script. The following is valid Python code:

Hey Bitcoiners, here are my short Python 3 scripts to generate a Bitcoin address. A few months back I wrote some Python 3 scripts to generate Bitcoin addresses. They work just like Brainwallet does, and in fact are 100% comaptible with brainwallet - you can copy the private key into brainwallet and expect everything to work. Jan 21, 2016  A Bitcoin python library for private + public keys, addresses, transactions, & RPC - blockstack/pybitcoin. Generating the EC private key. First of all we use OpenSSL ecparam command to generate an elliptic curve private key. Ethereum standard is to use the secp256k1 curve. The same curve is used by Bitcoin. This command will print the private key in PEM format (using the wonderful ASN.1 key. What is a Private Key? A private key is a secret 256-bit long number randomly selected when you create a Bitcoin wallet.This is the address which enables you to send the Bitcoins to a recipient’s address. You never share the private key to anyone. If you do not have an opaque private key (I think that'd involve specialist hardware, so not likely), you can get access to the private numbers information via the key.privatenumbers method of the private key object, at which point you can access the value itself as an integer number; the.privatenumbers method produces a EllipticCurvePrivateNumbers object with a.privatevalue attribute, a Python int.

Python 2.5 – 2.7 is required. Each time you run this script, it generates a Bitcoin address with a matching private key.

So, what’s going on here? Basically, this little script gives you the ability to throw some money around. Obviously, I don’t recommend doing so. I just think it’s cool that such a thing is even possible. Allow me to demonstrate.

Sending Bitcoins to One of These Addresses

Private

To show that the above Python script generates working Bitcoin addresses, I’ll go ahead and send 0.2 BTC – that’s currently over $100 worth – to the first address shown in the above screenshot. I’ll use Bitcoin-Qt, the original Bitcoin desktop wallet.

Here’s the transaction verified on Blockchain.info. Goodbye, 0.2 BTC!

Now, if I didn’t have the private key corresponding to 1AbbYb365sQ5DpZXTKkoXMCDMjLSx6m3pH, those bitcoins would be lost forever. Fortunately, I do have the private key. It was generated by the Python script too.

Recovering Those Bitcoins

To recover those bitcoins, I’ll use another desktop wallet called Electrum. Under Wallet → Private keys → Import, I can enter the private key:

…and presto! Electrum considers those 0.2 BTC mine to spend once again.

To make sure, let’s send them back to another address.

Here’s the final transaction verified on Blockchain.info.

There you have it. We’ve successfully sent money to – and more importantly, back from – a Bitcoin address that was generated by some code shaped like a Bitcoin logo.

What Does This Illustrate About Bitcoin?

Bitcoin addresses are created out of thin air. First, the script generates a pseudorandom number – that’s the private key. It then multiplies that number by an elliptic curve point to find the matching public key. The public key is shortened by a hash function, producing a Bitcoin address. Finally, both private key and address are encoded as text. Most Bitcoin wallet applications generate addresses in exactly this way.

Randomness ensures that each address is unique. With addresses created out of thin air, you might worry that two different Bitcoin wallets will eventually generate the same address. That’s not impossible, but with a strong pseudorandom number generator, it’s very, very, very, very, very, very, very, very unlikely. There are 2160 possible Bitcoin addresses. If you were to generate one million addresses per second for 5000 years, you’d be more likely to have a meteor fall on your house than to ever see the same address twice.

You must keep your private keys safe! The security of your bitcoins depends entirely on your ability to keep your private keys secret. Normally, your collection of private keys is stored in a wallet, so it’s absolutely critical to keep that wallet safe – whether it’s stored online, encypted to a file on your hard disk, or printed on paper. /office-2007-phone-activation-key-generator.html. If you lose access to your wallet, you lose your bitcoins. Likewise, if a thief gains access to your wallet, and bitcoins are still stored at any address inside it, he or she could steal those bitcoins within seconds. Indeed, such thefts happen regularly.

In researching Bitcoin, I found that there are a lot of smart people who understand Bitcoin very well, and a lot of people who know almost nothing about it. Luckily, the first group has created plenty of resources for learning more. This post was pieced together from information on Wikipedia, this blog post, the Bitcoin wiki, and the original white paper.
