I can see you are looking to extract the private key from the Mnemonic phrase using Python and Litecoin wallets.

Why do we need a private key?

—————————

A private key is required to check transactions in a blockchain network. When you create a new account or send cryptocurrency, your private key (along with the relevant public address) is stored securely in the wallet.

How to extract the private key from a mnemonic phrase:

——————————————————————————————————————————————————————————— ——– ——-

You can use Python and the Cryptograph Library to achieve this. Here is an example of how to generate a private key from a mnemonic phrase:

Installation of the required libraries

`bash

PIP Install Cryptography

Sample code

`Python

By cryptography.fernet Import Fernet

Import on base 64

Import json

By cryptograph.hazmat.primites Importization Serialization

By cryptography.hazmat.primites.asymmetric Pading Pading

By Cryptography.hazmat.backens Import Default_backend

Import hashlib

def Load_private_Key_from_mnemonic (Mnemonic, password = no):

“” “” “

Load a private key from the mnemonic phrase.

Argus:

Mnemonic (Str): Mnemonic phrase.

Password (Str, optional): Password for the wallet. If provided,

This password alone is used to generate the private key. Otherwise,

No private key is generated.

Returns:

Bytes: A private key like a JSON string.

“” “” “

Create an object of Fernet cipher

f = fernet ()

Load MneMonic phrase from file or database (optional)

In an application in the real world, you must keep the mnemonic phrase safe.

with Open (“mnemonic_phrase.txt”, “rb”) as f:

mnemonic_bytes = F.read ()

Password = “”

Optional

If not a password:

Generate a new private key for the first time

Private_Key = Fernet.Generate_private_Key (

Coding = “UTF-8”,

Backed = default_backend (),

Use_Keygen = TRUE,

))

Print (F “Generated private key: {Private_Key.private_bytes (

encoding = serialization.encoding.pem,

Format = Serialization.privateFormat.Raditionalopenssl,

Encryption_algorithm = serialization.Noencryption ()

)} “)

Encrypt the mnemonic phrase using the generated private key

encrypted_mnemonic = fernet.encrypt (

mnemonic.encode (“UTF-8”),

Padding.oaep (

mgf = patding.mgf1 (algorithm = hashlib.sha256 ()),

algorithm = hashlib.sha256 (),

label = none,

))

))

Load the private key from a json file

With Open (“Private_Key.json”, “RB”) as f:

Private_Key_bytes = F.read ()

Convert the encrypted mnemonic phrase to bytes

Encrypted_mnemonic_bytes = Base64.b64Decode (encrypted_mnemonic)

Return Private_Key_Bytes, Encrypted_MneMonic_Bytes

Exemplary use

mnemonic_phrase = “your_mnemonic_phrase_here”

Password = “”

Optional

Private_Key_bytes, encrypted_mnemonic_bytes = Load_private_Key_from_mnemonic (mnemonic_phrase, password)

Print (“Private Key (JSON):”)

Print (Private_Key_Bytes)

Print (“\ nencrypted mnemonic phrase:”)

Print (encrypted_mnemonic_bytes.hex ())

`

How to use this code:

• Keep the Mnemonic phrase in a file or database.

• Set a password if it is provided for decryption.

• Pass the encrypted mnemonic phrase as an argument when calling Load_private_Key_from_mnemonic.

• The private key is generated and returned as JSON String.

Note that this conversion suggests that you use the Fernet cipher algorithm with the SHA-256 hash. You may need to adjust these settings based on your specific requirements.
