Generate Private Key From Address

Jun 13, 2018 Learn how to hack Private Key's from Bitcoin Addresses by reversing the mathematics. Music by Cannibal Monkey - and Sh. I'm paranoid that I've been sending bitcoins to the paper bitcoin addresses where somehow at sometime my saved private keys got corrupted. So from time to time I want to run a script, python or whatever, to check if my private keys do correspond to the public address that I've been sending bitcoins to.

All Bitcoin private keys is simply an integer between number 1 and 115792089237316195423570985008687907852837564279074904382605163141518161494337 or HEX: from 1 to 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141. The integer range of valid private keys is governed by the secp256k1 ECDSA standard used by Bitcoin.

  • There are random generated Bitcoin private keys, converted into WIF format and hashed to addresses. After getting Bitcoin address we check the quantity of transactions (Tx) and get its balance. If you see any address with transactions, we will store this address into leak database and will try to notify the owner.
  • The generatepublickey function's parameter is private key. I find the public key is generated by hashing private key in your code. I find the public key is generated by hashing private key in your code.

We just generate a range of these integers in sequence, divide into pages and add to our URL:
For example: http://www.AllPrivateKeys.com/1157920892373161954235709850086879078528375642790749043826051631415181614942

For more convenient using, we convert private key number to WIF format.

WIF is an abbreviation of Wallet Import Format (known as Wallet Import/ Export Format). WIF simplifies import/ export of a private key.

In order to make copying of private keys less prone to error, Wallet Import Format may be utilized. WIF uses base58Check encoding on a private key, greatly decreasing the chance of copying error, much like standard Bitcoin addresses.

  1. Take a private key.

  2. Add a 0x80 byte in front of it for mainnet addresses.

  3. Append a 0x01 byte after it if it should be used with compressed public keys. Nothing is appended if it is used with uncompressed public keys.

  4. Perform a SHA-256 hash on the extended key.

  5. Perform a SHA-256 hash on result of SHA-256 hash. Working diablo 2 cd keys.

  6. Take the first four bytes of the second SHA-256 hash; this is the checksum.

  7. Add the four checksum bytes from point 5 at the end of the extended key from point 2.

  8. Convert the result from a byte string into a Base58 string using Base58Check

The process is easily reversible, using the Base58 decoding function, and removing the padding.

A compressed address is just the way of storing a public key in fewer bytes (33 instead of 65). There are no compatibility or security issues because they are precisely the same keys, just stored in a different way. The original Bitcoin software didn't use compressed keys only because their use was no disadvantages other than that a little bit of additional computation is needed to validate a signature.

You will see 20 random generated private keys, addresses, quantity of transactions and current balance to each Bitcoin address.

What is your chance to get luck ?

Yes, it's a rare chance tending to zero. Nobody is supposed to get these Bitcoins.

Can Google crowl all pages and compromise private keys ?

Theoretically, some private keys and Bitcoins addresses can be vulnerable, because Google search engine (Bing, Yandex etc..) can index some pages with private keys and addresses. But indexing all the pages is a huge array of keys.

For example: one of our pages with 100 addresses is about 40 978 Bytes. Try to divide the number of all the addresses into 100 (rows per page), multiply by 40 978 Bytes and divide into 137438953472 (one TerraByte).

You will get 345,238,967,039,530,911,720,582,795,073,715,758,043,805,378,040,119,207,565,323,040,414,160 TeraBytes of pages (!)

Currently, nobody has ever had a hard drive with such kind of volume.

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

$ python3 genaddress.py

$ python3 genaddress.py -p 'correct horse battery staple'

Private Key Definition

$ python3 genaddress.py -t -c
