Python Bitcoin Public Key Generator

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:

Python 2.5 – 2.7 is required. Windows server 2008 product key generator. 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

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.

So, i found 123,000 Bitcoin Addresses with 1+ BTC from 2009 to 2013 and NEVER made a transaction, therefore, lost BTC. It is just like huge pirate boats in the bottom of the ocean filled with treasures. The following are code examples for showing how to use Crypto.PublicKey.RSA.generate.They are from open source Python projects.

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. 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.
