Code:

>>> from mnemonic import Mnemonic
>>> mnemo = Mnemonic("english")
>>> xprv = '419ff3b824753f296223325a300a694a9641135558eedda79d9cb74f046e1457'
>>> len(xprv)
64
>>> xprv_bytes = bytes.fromhex(xprv)
>>> len(xprv_bytes)
32
>>> mnemo.to_mnemonic(xprv_bytes)

Yes, that works! Thank you!

Both xprv and seed are in hex. I've already told you.
I need xprv and seed to be converted to xprv in base58 format, seed to words.
--snip--

At least from seed (in hex format) to words it should be straightforward. An example,

Code:

>>> from mnemonic import Mnemonic
>>> mnemo = Mnemonic("english")
>>> xprv = '419ff3b824753f296223325a300a694a9641135558eedda79d9cb74f046e1457'
>>> len(xprv)
64
>>> xprv_bytes = bytes.fromhex(xprv)
>>> len(xprv_bytes)
32
>>> mnemo.to_mnemonic(xprv_bytes)
'dose zebra unlock employ fault net mass green focus leopard olympic news goat meadow fever build tank diagram grunt hub utility damage eyebrow view'

Take note it require library from https://github.com/trezor/python-mnemonic. And in case i also misunderstood what you want to achieve, i would suggest you to add expected input/output with some examples to your question.

Always please read the first post - it is all explained there.

No, this script does not do what I need.
It does more encode the xprv (not this direction which I need) by sha256 and does not give seed phrase in text.

Please stop trolling.

Maybe, but you haven't cleared up what you want to do, and it's difficult to understand what is what from your wording.

I need xprv and seed to be converted to xprv in base58 format, seed to words.

So you want hexadecimally represented xprv to base58 and hexadecimally represented seed to words (AKA, seed phrase).

I don't know python, so I asked ChatGPT. Isn't this what you want basically? (for xprv only)

Code:

import base58
import binascii

def encode_xprv(hex_xprv):
   # Convert hex xprv to bytes
   xprv_bytes = binascii.unhexlify(hex_xprv)

   # Add version byte (0x0488ADE4) to the beginning
   version_bytes = bytes.fromhex('0488ADE4')
   xprv_bytes = version_bytes + xprv_bytes

   # Add 4-byte checksum to the end
   checksum_bytes = hash256(xprv_bytes)[:4]
   xprv_bytes += checksum_bytes

   # Encode the result in base58
   encoded_xprv = base58.b58encode(xprv_bytes).decode('utf-8')

   return encoded_xprv

def hash256(data):
   # Compute SHA256 hash of data
   import hashlib
   sha256_hash = hashlib.sha256(data).digest()

   # Compute SHA256 hash of SHA256 hash
   sha256_twice = hashlib.sha256(sha256_hash).digest()

   return sha256_twice

# Example usage
hex_xprv = "0488ade4000000000000000000d094cde7b1ca97a07c82d73bbd6b018f6b3e6d94c6c122f1b883e2e8fa6e76c261d96e4c4baebf8af4b4d05cfef4b1c2b47fa8f8640eb9a16f4d39473df7"
encoded_xprv = encode_xprv(hex_xprv)
print(encoded_xprv)

These are hex numbers.

Which are represented in hex?

Quote from: pbies on March 14, 2023, 10:44:26 AM

I need at least seed to be converted to text.

But seed is supposed to be in hex. Seed phrase is in text.

Quote from: pbies on March 14, 2023, 10:44:26 AM

Also xprv is in hex format that modern wallets do not accept.

It sounds very weird that you have a master private key in hex, as it always comes in base58.

It seems to me your situation is an XY problem.

No, it is not XY problem.

Just need to convert xprv and seed to "readable" values, using given password. Mostly by Python code.
I already said that three times.

What do you mean you want to decipher an xprv / seed? If you have the keystore and the password to unlock it, then you can decrypt everything encrypted in it.

Quote from: pbies on March 13, 2023, 11:06:56 AM

I don't know - I have only .json file and password for it.

Something tells me you bought someone else's wallet which supposedly have coins you try to gain access to. If that's the case, it's most certainly a scam.

I have no code to decrypt neither and convert them to "readable" format.

Wallet Client? electrum i guess?

I don't know - I have only .json file and password for it.

So how did you manage to get your hands on that JSON file and its password?
Hope you're not trying anything illegal! Wink

If you know the password for your Keystore file, you should be able to access your wallet using a compatible software or wallet. Many wallets support importing Keystore/JSON file, which would allow you to access your funds. You don't need any special tool for that.

What software did you use to create the Kystore/JSON backup file?

I am asking for code (mostly Python) way.

If the JSON would be whole I could import it, it isn't.

No wallet software is applicable here.

I want to decipher xprv and/or seed because I know the password, but I have no tool to do that.

How can I do that?

I have .json file with keystore.
I know http://iancoleman.io/ but it does not help me as this is the other way around.
I have JSON dump with: keystore = xprv and seed.
