Addressgen is a utility to generate private keys and their correspondingaddresses for cryptocurrencies based on secp256k1. Currently, only Bitcoin,Dogecoin, and Litecoin are supported, but in the future I will add support formore.

Addressgen is tested on Linux and Windows, requires Python 3.3 and a copy oflibeay32.dll (Windows, obtained from OpensSL packages) or libssl.so (linux,openssl package).

Run 'python3 genaddress.py'

Arguments

Examples

1. From the secret value to a private key. This is step is trivial. Actually, the output of the hashing above taken as a 256-bit unsigned number is already the private key, what is commonly called the secret exponent. But we are used to see those pretty private keys beginning with a 5, so let’s see how it is encoded.

3. Here's a self-contained Python script that does the conversion. You can check its work by comparing to entering your private key as the 'Secret Exponent' at Brainwallet.I took the script from this Bitcointalk thread and stripped out unnecessary stuff (like the code to use the public key to sign a message and verify that signature).
4. Sep 22, 2017  The Private Key WIF is a code that needs to be keep secret since it can be used to spend any funds that have been sent to the corresponding public key. Keys can be encoded in a number of different formats. The most popular encoding formats (WIF, WIFC, HEX, B64) are.
5. As per my understanding user seed somehow gets generated into a private key, then using that private key to derive the public key and from that you derive the address. Does anyone have any further information on how this achieved with javascript or what is the architecture for this kind of setup. Any help on understanding it would be great.

Jan 29, 2020 This ensures that the sender/signer is the real owner of bitcoins. How Is A Bitcoin Private Key Generated? Elliptic Curve Digital Signature Algorithm or ECDSA is the asymmetric cryptographic algorithm used by Bitcoin to generate public and private keys. And this asymmetricity ensures that funds can be spent by the rightful owners only.

Brainwallets are Bitcoin wallets generated uniquely from a passphrase that the users keeps in his mind so that it is required and sufficient to move the funds.

But what is actually the process that takes a password and spits a Bitcoin wallet address? Let’s dissect it.

1. From a password to a secret value

Generate Bitcoin Private Key Based On Secret Exponent Number

So, we have a password, but we need a fixed-size (256-bit) secret value to make our private key. /gta-iv-serial-key-unlock-code-generator.html. This step can be done in a number of ways as it boils down to hashing the password but is crucial to the strength of the resulting brainwallet.

Let’s have a look at how popular Brainwallet generators do it. (As of 20131204)

A lot of them just take the unsalted SHA256 hash of the password. This is wrong. Because SHA256 is fast and that means that an attacker can pregenerate huge tables of all possible brainwallets to monitor and empty them (Spoiler: they do). This kind of thing – turning a human supplied password into a public hash – is exactly what password stretching are for, and not using them here is an oversight as bad as not using them to store website user passwords, if not worse since here the hashes (the addresses) are public by default.

(Hint: use WarpWallet. It’s built by people who know what they are doing, and employs a proper KDF, making attacking your wallet really difficult.)

2. From the secret value to a private key

This is step is trivial. Actually, the output of the hashing above taken as a 256-bit unsigned number is already the private key, what is commonly called the secret exponent.

But we are used to see those pretty private keys beginning with a 5, so let’s see how it is encoded. That format is called WIF, Wallet import format, and it is pretty handy as it has checksumming built in and employs a charset without confusing characters (Base58Check) – exactly like a Bitcoin address.

3. From a private key to a public key

As Wikipedia tells us a ECDSA private key is just the scalar product of a private key (the secret exponent) and the curve – secp256k1 for Bitcoin – base point. How to do that is complex, but let’s just take it for granted, as you’ll either use a librarty for this or research further by yourself.

What we get out of that operation is a pair (x, y) denoting a point on the curve, our public key.

4. From the public key to a Bitcoin address

We’re almost there! Now we just need to turn that ECDSA public key into a standard Bitcoin address.

The process is the same as point 4, executed on the SHA256+RIPEMD160 hash of the packed x and y values. Go go snippet:

And it’s done!
