Ethereum: How to derive the P2WPKH output script Bech32
Understanding underlying blockchain structures and transactions is essential when building applications related to encryption. One aspect of Ethereum architecture is the use of titles, which can be quite complicated for newborn. In this article, we plunged into how to derive a P2WPKH BEC32 title (public key protected private key).
Overview of the P2WPKH Exit Script
The P2WPKH output script is one of two types used in Ethereum transactions. The other type is PPVRF (Diffie-Hellman is a public individual). In this context, we focus on the P2WPKH output script. The P2WPKH output script represents a private key protected by a public key using the digital signing algorithm of the elliptical curve (ECDSA).
Title Bech32 of the P2WPKH output script
From the P2WPKH output script, you must follow these steps to conduct the title Bech32:
- Determine the public key : The public key is usually portrayed as a hexadecimal string and can be accessed directly from the script.
- Extract the private key : You must remove the private key from the script. This usually includes the private -cavalous value extract associated with the public key.
In Ethereum, the P2WPKH output script format uses a specific syntax to encode the private key in base64 format. The coded private key is removed by removing the 0x guide ... prefix and adding the remaining characters at the end of the hexadecimal string.
- Generate Bech32 : Once you have the private key encoded, you can generate Bech32 with a special algorithm or directory.
Example Code
Here is an example of Python script that shows how Bech32 can be derived from a P2WPKH output script:
`Python
Import base64
DEF deriv_bech32_address (p2wkh_output_script):
Extract the private key of the script (assuming it starts with ‘0x …’)
Private_Key = p2wkh_output_Sript [10:]
Make Bech32 Using a directory like ECRECSOVER or BECH32.py
Import
Rec = ECRECOVER.ECRECOVERER ()
Addr = rec.from_private_bytes (base64.b64decode (private_key)))
Return addr
Using examples:
p2wkh_output_script = “0x … (the p2wpkh output script)”
Bech32_address = derise_bech32_address (p2wkh_output_script)
Print (bech32_address)
Output: Your title Bech32
`
IMPORTANT ASPECTS
Remember that this is a simplified example and you cannot cover all lives. You need to know the possible safety risks associated with the calculation of private keys, such as exploring confidential information.
Projects related to encryption remain essential to maintaining themselves -dattered with the latest developments and proven practices to cooperate with Ethereum titles and scripts.
Following these steps, you can now derive P2WPKH output bech32 titles and understand the operation of the deepest Ethereum architecture.
