Ethereum: HMAC “Bitcoin Seed” for BP32
In the world of cryptocurrency, understanding of basic technology is crucial for every serious investor or developer. One of such technologies is BP32, the method used by Ethereum to create the main key key. In this article, we will examine how PyBitcointools uses HMAC (key to authentication) to calculate Bitcoin seeds for BP32.
What is bpp32?
BP32 is a set of rules and interfaces that determine how to create a private seed key using blockchain ethereum. It allows users to encrypt the main private key, which can then be used to generate many public keys.
pybitcointools and hmac
Pybitcointools is a popular Python library for interaction with Ethereum Network. One of its functions is “BP32_Master_KEY, which takes two parameters: 'Seed' (seeds to create the main private key from) and vbytes = mainnet_private ‘. The function returns the Bajty object, representing the generated main private key.
process hmac
To calculate Bitcoin with HMAC, we must follow the following steps:
- Create the HMAC object: We use the “hmac.new
function to create a HMAC object with the seeds supplied and input (in this case by_string_to_bytes (" Bitcoin seeds ").
- Update the HMAC
object: We update the HMAC object using the "UDDERT" method, going to other bytes of the Bitcoin Seed input stream.
- Calculate digestion : Finally, calculate the absorption of the HMAC object using the "Digest" method.
assembly of all this
Here is the PyBitcointools code that uses HMAC to calculate bitcoin seeds for BP32:
Python
Def bpp32_master_key (seeds, vbytes = mainnet_private):
I = hmac.new (from_string_to_bytes ("Bitcoin Seed"), DigestMod = hashlib.sha512)
Return I.digest ()
Example use
To use this function, just name it with seeds and entering data as arguments:
`Python
seed = b "your_seed_here"
Digest = bpp32_master_key (seeds, vbytes = mainnet_private)
Print (Digest)
Note that “Od_String_To_bytes (” Bitcoin Seed “) is assumed that it is a function that transforms Bitcoin seeds into bytes. This function is not defined in this article.
Application
To sum up, PyBitcointools provides a effective way to calculate bitcoin seeds for BP32 using HMAC. Understanding how this process works and you will apply it to your own code, you can deeply look at the basic Ethereum technology. Remember to always use safe coding practices and think about the potential security effects, generating private keys in the Ethereum network.
