Dec 28, 2013  Addressgen is a utility to generate private keys and their corresponding addresses for cryptocurrencies based on secp256k1. Currently, only Bitcoin, Dogecoin, and Litecoin are supported, but in the future I will add support for more. I'm facing an issue regarding generating address from private key. I got the master private key from electrum as well as from bitcoin core that is starts from. Question is: how i convert my private key that i got from electrum or bitcoin core wallet and generate valid address from it using bitcoinJ – Muhammad Saad Mar 21 '18 at 7:31.

• 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.
• 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.
• How to steal Bitcoins¶ Every Bitcoin address is based on a secret key, from which the public key (associated to a Bitcoin address) is calculated. Once you have the private key for an address, you have the control of that address and can use it to transfer funds. This secret key.

A private key represented as random words is safe. For a brute-force attacker such a private key is just as difficult to guess as the fully random 64 character bitcoin private key. Also, words are much easier to write down or even remember. Though it's best to write them down or print them and put them in a safe place even if you have a great memory, just in case. Trusted bitcoin wallets such as the Electrum bitcoin client use wallet words as well.

As seen in our guides to elliptic curve cryptography and how to create a Bitcoin Private key – a public key is in fact just coordinates on the Bitcoin curve calculated through multiplying the generator point by the private key number.

x coordinate= 7a633d546e723c3f41794549272f63617057382a227b6d393b35303d38
y coordinate= 44437a7439746e35565d3a27713c706423557e78444f4e767a22515724

These numbers are shown in Hexadecimal format, or 256 binary digits shown as 64 hexadecimal digits. If the number was shown in decimal format it would be 10⁷⁷ figures long.

If you take these two coordinates and concatenate them i.e. join them end to end to make a 128 characters long string in Hexadecimal format, and then hash them whilst adding to the front a 1 (to indicate an address on the main network, if the address was for the testnet it would start with an m or an n).

Public_K=G Private_K=(x,y)
Address=(Network Version) & Ripemd160(sha256(x&y) & checksum

There is also the checksum to add which is essentially a hash of the address of the hash of the address – this is to check that the address is what it is – to stop typos et al.

Checksum=First four bytes of sha256(sha256((Network Version)&Ripemd160(sha256(x&y))

The last step is to change the coding structure into a more readable format or Base58 in the case of Bitcoin. Base 58 is similar to base 64 but with a few characters removed. Base64 uses A-Z, a-z, 0-9, + and /.

Base 58 uses the same symbols but removes +,/,0,O, I and l. All the symbols that could be confused for each other are removed making the format readable. The end result is a Bitcoin address of between 27 and 34 characters long! Such as below.

Notice that this address begins with 1 meaning it is a Bitcoin main network address and also that the first three characters spell the word Bit – in other words this is a vanity address.
