Verification and Signing Keys Bug

[bluekapo]

Greetings!

I'm trying to sign a transaction with keys I got from an HDWallet. I need to sign it with stake and spend (payment) keys. So I get vkeys like (wallet is HDWallet object):
Stake:

hdwallet_stake = wallet.derive_from_path("m/1852'/1815'/0'/2/0")
stake_public_key = hdwallet_stake.public_key
stake_vk = StakeVerificationKey.from_primitive(stake_public_key)

Spend:

hdwallet_spend = wallet.derive_from_path("m/1852'/1815'/0'/0/0")
spend_public_key = hdwallet_spend.public_key
spend_vk = PaymentVerificationKey.from_primitive(spend_public_key)

The vkeys I got above are exactly the ones I need (their hashes are the same hashes that can be found in the RequiredSigners of a transaction)

After that I get signing keys:
spend_sk = SigningKey.from_primitive(spend_public_key)
stake_sk = SigningKey.from_primitive(stake_public_key)

Signing transaction with this set of keys results in InvalidWitnessUTXOW error on submit.

I tried to get back vkeys from skeys to compare it:

spend_vk_2 = PaymentVerificationKey.from_signing_key(spend_sk)
stake_vk_2 = StakeVerificationKey.from_signing_key(stake_sk)

spend_vk and spend_vk_2 as well as stake_vk and stake_vk_2 hashes are completely different.

I've tried to change Signing key to extended version or to StakeSigningKey/PaymentSigningKey and to me it didn't make any changes.

I would also like to get in touch with Jerry, if it's possible, to ask a few questions about cardano and this library as well as kindly ask for a helping hand with one of my projects.

I can give all the needed information.

Thanks in advance!

Hi @bluekapo , have you tried creating your vkeys from ExtendedVkey classes?

spend_vk_2 = PaymentExtendedVerificationKey.from_signing_key(spend_sk)
stake_vk_2 = StakeExtendedVerificationKey.from_signing_key(stake_sk)

If a signing key is extended, its vkey has to been created from extended vkey class.

Thanks for help and sorry for the late response, I was a bit busy. @cffls I tried this before posting the bug, but it didn't help. Just had to restart the whole system. I have no clue what that was. For everyone that will happen to have the same bug: just use extended keys.

Thanks for the update @bluekapo. Extended keys are supposed to work. Will try to create a test case for it.
