Convert a Private Key to bitcoin with Python and PHP

In this article, we examine the two ways to convert the private key in JSON format to the appropriate Bitcoin address.

Python

Python is a popular language of scripts, data analysis and automation. The “Cryptography” directory is used to support cryptographic operations and “hashlib” to produce abbreviations. Here is an example of the code that transforms the private key from JSON format to bitcoin with Python:

`Python



Import Json

Cryptography.hazmat.hazmat.hazmat

with Crieptography.hazmat.Promthy.Symmetry imports

Import the cryptography.hazmat.hazmat.primths to Hames

cryptography.hazmat.Backends import_backend

Def Load_Private_key (Json_Data):

    private_key = json.lylads (json_data) ["private"]

    Key_type = json.lylads (json_data) ['Keytype']

    If Key_Type == "Hex":

        Return byte.fromhex (private_key)

    ELIF KEY_TYPE == 'PKCS8':

        open ("private_key.p", "wb") as f:

            F.write (prive_key.encode ())

        private_key_pem = open ('private_key.pem', 'rb'). Read ()

        Private_key_bytes = Serialization Decode ('UTF-8')

        Back to private_key_bytes

    otherwise:

        Consideration Value Source ("Unreasonable Key Type")

Defvert_Private_to_bitcoin_address (Privát_key):

    prive_key_bytes = load_private_key (json.lylads (private_key) ['private']))))))

    Bitcoin_address = byte.fromhex (prive_key_bytes)




Calculate the Bitcoin title combined with the first 34 signs of the sixteen string

    Bitcoin_address = bitcoin_address [: 34]


    Return to Bitcoin_address



Using a sample:

private_key_json = '{"private": "5jyjwrrd7sbqzl9kr9dgrLEgleqzehptcvhc5t8zvwgs9ic"} "}'} '}'} '}'} '}'

private_key_hex = private_key_json ['private']

Bitcoin_address = convert_private_to_bitcoin_address (private_key_hex)

Print (bitcoin_adress) 

output: 18v7u8ynhkwg94444tckzyyj32hb6fdfpvqf

using PHP

PHP is a popular language to create sites, scenarios and automation. We will use the “HASH” function to produce Private Key Commands in JSON format. Here is an example of the code that transforms the private key from JSON format to Bitcoin:

`Php



Convert on Function_Private_to_bitcoin_address ($ private_key) {{

    $ privey = json_decode ($ prive_key, true);


    // Fill the Private button from the file (replace your own)

    $ private_key_pem = fopen ('access path // private/key.pem', 'rb');

    $ private_key_bytes = freed ($ private_key_pem, fileize ('access path // private/key.pem'));

    fclose ($ private_key_pem);


    // convert Private Key's bytes to a hexadecimal string

    $ priveyhex = bin2hex ($ privey_bytes);


    // Calculate the Bitcoin title combined with the first 34 signs of the hexagonal cord

    $ Bitcoinaddress = subst ($ priveyhex, 0, 34);


    return $ bitcoinaddress;

}

// using a sample:

$ prangejson = '{"private": "5jyjwrd7sbqzl9kr9dytgrxylqzehptnctcvhc5t8zvwgs9ic"}';

$ bitcoinaddress = convert_private_to_bitcoin_address ($ private);

Print ($ Bitcoinaddress) // Exit: 18V7U8NHKWG944TCZYYJ32HB6FDFPVQF

It should be remembered to replace the path // private/Key.pem ” ‘The actual path of the private key file. Also make sure that you support any error or exception that may occur during the conversion process.

Json -Data Sample

Ethereum: convert private key to bitcoin address using python or php

You can use the following examples of JSON data as a template:

`Json



{{

  "Private": "5jyjwrd7sbqzl9kr9dGRSLXYLQZEHPTCVHC5T8ZVWGS9IC",

  "Keytype": "Hex"

}

Replace the “Private” field for the actual private key in hexadecimal format. The “Keytype” field must be set to hex in this example.
