Then you can import that private address into a new descriptor wallet.
You cannot import a seed manually with
sethdseed in a descriptor wallet. It has to be a legacy wallet, otherwise you'll encounter the error:
Only legacy wallets are supported by this command (code -4)

Here's a quick Python program for you:
import hashlib
import base58
def private_key_to_wif(private_key_hex, network_byte=0x80):
# convert private key from hex to bytes
private_key_bytes = bytes.fromhex(private_key_hex)
# add network byte prefix
extended_key = bytes([network_byte]) + private_key_bytes
# checksum = :4 from sha256(sha256(key))
checksum = hashlib.sha256(hashlib.sha256(extended_key).digest()).digest()[:4]
# append the checksum to the extended key
extended_key += checksum
# convert to base58
wif = base58.b58encode(extended_key)
return wif.decode('utf-8')
if __name__ == "__main__":
private_key_hex = input("Enter the Bitcoin private key in hex format: ")
try:
wif = private_key_to_wif(private_key_hex)
print("WIF:", wif)
except ValueError:
print("Invalid private key input.")
It takes as input a 256-bit private key, and converts it to WIF. You can create a new file, paste it there and run it with
python3 file.py. Note that you must have base58 installed. To do it, run
pip install base58 from the terminal.
