SEP-0046: Key Sharing Method for Stellar Keys #1601

tupui · 2025-01-03T15:36:19Z

In the Python SDK we added support for Shamir Secret Sharing as a way to split mnemonics into parts.

Shamir Secret Sharing is standardised here: SLIP-0039

Let me know if I should extend anything

We added support here:

StellarCN/py-stellar-base#1012

and see also this follow-up

StellarCN/py-stellar-base#1015

Code used to generate the SSS mnemonic phrases

Hi @tupui, I was wondering if it would be better to add test data for multiple groups? Although it is not widely used, and even Trezor only supports a single group. However, the SLIP 39 specification does include it, and having test data would give someone more confidence if they wanted to implement it.

However, the SLIP 39 specification does include it, and having test data would give someone more confidence if they wanted to implement it.

I can have a look at it 👍

@overcat done 😃 Let me know if I should adjust anything.

For the record, here is the small helper I used:

mnemonic = ...
passphrase = ...
seed_raw = StellarMnemonic("english").to_bip39_seed(mnemonic=mnemonic, passphrase=passphrase)
# Shamir with the BIP-39 seed
shamir = shamir_mnemonic.generate_mnemonics(
    group_threshold=2,
    groups=[(2, 3), (1, 1), (2, 3)],
    master_secret=seed_raw,
    passphrase=passphrase.encode(),
)

Hi @tupui,

BIP-0039 seed should be used to derive the multiparts menomonic. The parts are non-deterministic and any derivation
leads to the same set of keys. As recommended for single mnemonic codes, we recommend using 256 bits of
entropy. Which leads to 33 word mnemonic phrases.

I think this is incorrect. Have you noticed that all the test data you generated, regardless of the BIP39 word length, has a SLIP39 word length of 59?

Moreover, there is also such a description in https://trezor.io/learn/a/slip39-faqs:

Can I convert my existing BIP39 wallet into a SLIP39 wallet?
While technically possible, converting a BIP39 wallet to a SLIP39 wallet is not recommended due to several limitations and security concerns. Trezor Suite will not allow you to convert your BIP39 wallet to a SLIP39 wallet.

Here is a correct script for generating test data. Additionally, I suggest adding an entropy field in each test case.

import binascii
import os

import shamir_mnemonic

from stellar_sdk.keypair import Keypair
from stellar_sdk.sep.mnemonic import StellarMnemonic

# entropy = os.urandom(32)
entropy = binascii.unhexlify("00000000000000000000000000000000")  # 128 bits of entropy, Test 5
passphrase = ""
print(f"Entropy: {entropy.hex()}")

mnemonic = StellarMnemonic("english").to_mnemonic(entropy)
print(f"BIP39 Mnemonic: {mnemonic}")

bip39_seed = StellarMnemonic("english").to_bip39_seed(mnemonic=mnemonic, passphrase=passphrase)
print(f"BIP39 Seed: {bip39_seed.hex()}")

print("BIP39 KeyPairs:")
for i in range(3):
    kp = Keypair.from_mnemonic_phrase(mnemonic, passphrase=passphrase, index=i)
    print(f"Index: {i}, Public Key: {kp.public_key}, Secret: {kp.secret}")

mnemonic_phrases = shamir_mnemonic.generate_mnemonics(
    group_threshold=1,
    groups=[(2, 3)],
    master_secret=entropy,
    passphrase=passphrase.encode(),

)[0]
# Note: Due to the presence of the identifier, each generated mnemonic phrase is different, but they can all recover the same seed.
# https://github.com/satoshilabs/slips/blob/master/slip-0039.md#format-of-the-share-mnemonic
print(f"SLIP-0039 Mnemonic phrases: {mnemonic_phrases}")
slip39_seed = shamir_mnemonic.combine_mnemonics(mnemonic_phrases[:2], passphrase=passphrase.encode())
print(f"SLIP-0039 Seed: {slip39_seed.hex()}")

print("SLIP-0039 KeyPairs:")
for i in range(3):
    kp = Keypair.from_shamir_mnemonic_phrases(mnemonic_phrases[:2], passphrase=passphrase, index=i)
    print(f"Index: {i}, Public Key: {kp.public_key}, Secret: {kp.secret}")

I think this is incorrect. Have you noticed that all the test data you generated, regardless of the BIP39 word length, has a SLIP39 word length of 59?

Yes I noticed. This is because I am using the full BIP39 seed which is more than 256 bits. So we end up at the max which is 59 words. I should rephrase to add "at least".

I went with that route so that we can reuse the current cases. That works in the sense that we can be consistent (see my other script above with the consistency check).

I agree though that using a plain entropy field as you suggest looks better. I can regenerate all the data if we are fine with changing the original test cases (I have seen that these public addresses were reserved to avoid any issues.)

You can derive the plain entropy from the existing mnemonic words, so this should not change the existing test cases.

I see what you mean 👍 I will do that and also adjust the text to replace the BIP39 with it.

I adjusted for entropy.

The Stellar keys of BIP 39 and the Stellar keys of SLIP 39 are different. Are you willing to add it?

Additionally, this part only applies to BIP-39. Can you specify that? For example, m/44'/148' key (BIP39):

m/44'/148' key:

e0eec84fe165cd427cb7bc9b6cfdef0555aa1cb6f9043ff1fe986c3c8ddd22e3

The Stellar keys of BIP 39 and the Stellar keys of SLIP 39 are different. Are you willing to add it?

Sorry I don't understand what you mean.

Oh I see now (linked to the other PR.) If I start from the entropy and use it directly then yes keys will be different. To get the same keys I need to go with the to_bip39 as I had before. I wanted to have everything being consistent with a single set of Stellar Keys. But if we can't because we say we don't want to use BIP39 as transition then I can make a specific section for SLIP39 as you suggested.

(Would be so much easier to just use the normal mnemonic phrase as a secret for Shamir 😅)

LGTM! Your test cases have all been verified as correct. Now we need to wait for someone with write access to the repository to review it.

leighmcculloch · 2025-01-14T20:48:19Z

This is fantastic @tupui. Thanks for reviewing as well @overcat.

Because SEP-5 is final, the intent is it won't change. SEP-5 is an old and very stable SEP that wallets can say they support already in full. Expanding it is not ideal because that statement a wallet makes that it "supports SEP-5" changes.

Can the new text be moved into a new SEP? The new SEP can reference SEP-5, and operate as an extension.

tupui · 2025-01-14T21:31:58Z

Thanks @leighmcculloch 🙇

Great, I am happy to do this! Looking at e.g. SEP-44 being an extension of SEP-41, I can use that model to do the same here. SEP-45.

tupui · 2025-01-15T01:03:31Z

I updated the PR. Please let me know what you think 😃

Also feel free to add your names.

Overall, it looks great; I just added a little suggestion.

It's great to point that out. 👍

+## Design Rationale


It would be better to explain the reasons for choosing SLIP-39 here; in my opinion, Alternatives considered include: is a bit redundant.

SLIP-39 was chosen as the base standard because: 1. Industry adoption and testing 2. Hardware wallet support 3. ...

I rephrased a bit. Please feel free to add some suggestions.

Probably a naive question: skimming through the proposed text for SEP-0046, it seems to me like it's not much more than a pointer to SLIP-0039. If that's a correct statement, what is the goal of publishing this as a SEP?

Correct, this is why it started as being in the text of SEP-005. But being frozen we needed to move that to its own SEP. The point here is to endorse it and encourage wallets to implement the feature. Having some Stellar specific test cases would help towards that.
