unknown public key type

[godlovericea]

when i write program below, it panic err:

panic: unknown public key type

privateKey, err := keypair.DeserializePrivateKey(privateKeyBytes)
if err != nil {
    fmt.Println(err)
    return "", "", "", err
}
pub := privateKey.Public()
aAddr := types.AddressFromPubKey(pub)

how to transform crypto.PublicKey to keypair.PublicKey

I have read the source code
Such as:
https://github.com/ontio/ontology/blob/master/cmd/account_cmd.go#L438

https://github.com/ontio/ontology/blob/master/cmd/sigsvr/store/wallet_store.go#L225

how to transform crypto.PublicKey to keypair.PublicKey
or
how to transform crypto.PublicKey to common.Address

Where is the privateKeyBytes come from?

@laizy thank you very much

I have generated a keypair before , then cast to string , save it into my db
when I want to make tx, I get the prvString from my db, such as below

prv, _, _:= keypair.GenerateKeyPair(keypair.PK_ETHECDSA, nil)
prvString := hex.EncodeToString(keypair.SerializePrivateKey(prv))
privateKeyBytes , _:= hex.DecodeString(prvString )

If you want to send ontology transaction, you can use keypair.PK_ECDSA. keypair.PK_ETHECDSA is intend for ontology evm transaction.

The current workaround for your code is:

privateKey, err := keypair.DeserializePrivateKey(privateKeyBytes)
if err != nil {
    fmt.Println(err)
    return "", "", "", err
}
_, pub := keypair.FromEthereumPrivateKey(privateKey.(*ec.EthereumPrivateKey).PrivateKey)
aAddr := types.AddressFromPubKey(pub)
