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.
