assuming i have this

cat keystore-m_12381_3600_0_0_0-1715783445.json

{"crypto": {"kdf": {"function": "scrypt", "params": {"dklen": 32, "n": 262144, "r": 8, "p": 1, "salt": "3dea9c48bbb5ba32f3e5bcbf1377dd8371ac1eb5bda945b588fd5928141f21e6"}, "message": ""}, "checksum": {"function": "sha256", "params": {}, "message": "c23bebf91faabcfef2e97ec9969021cc7da51e69df185a92baea6a729c9d917b"}, "cipher": {"function": "aes-128-ctr", "params": {"iv": "4c48b5cc2e24a8a0cd37bd50d63eecbe"}, "message": "cba31e06650e4c680f4aa7b13ce65f969236c73446e95c6bc11fc922327a744c"}}, "description": "", "pubkey": "ae8276eb4f7be2b9d025198df394ebf56df3f9aa74e6eb7ef162a89aa8aff810eca907276a5d6ffbff2356a49bcce20c", "path": "m/12381/3600/0/0/0", "uuid": "6dbe932d-53e3-4c4f-be60-fe3e5ae1c7dc", "version": 4}

how can i use ethdo to generate the validator key and the secrets (validator passphrase) from this keystore?
( I am intending to use this in lighthouse beacon node)

I don't see any instructions for this particular case in the provided documentation

your guidance is highly appreciated!

The validator public key is already present in the keystore as "pubkey".

To obtain the private key you need to import the keystore into a wallet. For example:

ethdo wallet create --type=nd --wallet=import
ethdo account import --account=import/account1 --keystore=... --keystore-passphrase=... --passphrase=secret
ethdo account key --account=import/account1 --passphrase=secret

keystore can be the path to the keystore file rather than the data itself. keystore-passphrase is the passphrase that was used to create the keystore. You should replace secret with a proper passphrase to keep the private key secure.

Once you have the key you can remove the wallet with

ethdo wallet delete --wallet=import

thanks alot for the guidance!

if i understand correctly, the secret is actually the passphrase for the respective voting-keystore.json of each validator yes?

EDIT : closed the issue by mistake, i am still looking for help!

passphrase is the passphrase for the new account you are creating. keystore-passphrase is the passphrase for the keystore from which you are importing the private key.
