04:01:26 <m-relay> <r​ecanman:kernal.eu> First time
04:01:35 <m-relay> <r​ecanman:kernal.eu> I restarted monerod and the issue went away
04:01:47 <m-relay> <r​ecanman:kernal.eu> Just wanted to post it in case it was useful
16:58:40 <vthor> how do I derivate the public address and the view key from the spend key?
16:59:24 <m-relay> <m​cneb10:envs.net> the public address is a combination of the public view and spend keys
17:00:05 <m-relay> <m​cneb10:envs.net> https://www.getmonero.org/resources/moneropedia/address.html
17:03:02 <sech1> Private view key is normally generated from the private spend key (although 3rd-party wallets can do it differently)
17:04:12 <vthor> oh heck, so I need to arrive on the address first derivate the public spend key, secret view key -> public view key to generate a wallet. then I can also directly generate the wallet by myself :/ 
17:06:06 <m-relay> <m​cneb10:envs.net> iirc the private spend key is randomly generated, and the private view key is made by keccak 256 hashing the private spend key 10000 times
17:06:18 <m-relay> <m​cneb10:envs.net> then you can derive the public keys from the private keys
17:06:45 <vthor> I want to have the outcome compatible with monero-gui/cli/rpc and feather, my challenge is now to get from the secret spend key I created from polyseed to the complete wallet or to the correct seed phrase, I assumed wrongly that the key provided to monero.seed.Seed (in monero-python) is equal to the secret spend key, but isn't :S
17:07:31 <sech1> view secret key is just a keccak(spend secret key), if you create it with Monero CLI/GUI
17:07:41 <sech1> so it's just a keccak hash
17:07:56 <sech1> and sc_reduce32
17:08:18 <vthor> sc_reduce is from ed25519?
17:09:06 <sech1> yes, it's from src/crypto/crypto-ops.c
17:09:44 <vthor> hehe, there I have also still an issu open, because monero.seed.Seed a randomly generated seed, then restored wallet with monero-rpc leads to another seed phrase but the same wallet....
17:12:32 <vthor> so it's polyseed -> secret_spend_key -> ed25519.sc_reduce(keccak(secret_spend_key, rounds)) -> secret_view_key.
17:13:27 <vthor> then I need to get from both the public keys, the private keys are ed25519?
17:13:52 <vthor> and rounds = 1 or 10000?
17:14:00 <sech1> 1 round of keccak
17:14:37 <sech1> Private keys are ed25519
17:14:46 <vthor> will look first in src/crypto/crypto-ops.c before I make more unnecesarry questions... sorry, I'm a bit accelerated
17:15:24 <vthor> thank you very much sech1 :)
17:46:23 <m-relay> <r​ecanman:kernal.eu> vthor here's the original python reference implementation: https://ed25519.cr.yp.to/python/ed25519.py
17:49:21 <m-relay> <r​ecanman:kernal.eu> Another good resource: https://getmonero.dev/cryptography/asymmetric/edwards25519.html
17:58:42 <vthor> recanmen thank you, but it's shipped whith monero-python
18:03:20 <vthor> and I could create now everything by hand, but now it seems feather does something else then claimed :/ will see there, something doesn't add up.
