i tried this
package main
import
( "crypto/ecdsa" "crypto/elliptic" "fmt" "math/big"
"github.com/ethereum/go-ethereum/crypto/secp256k1" )
func Public(PrivateKey string) (publicKey string) { var e
ecdsa.PrivateKey e.D, _ = new(big.Int).SetString(PrivateKey, 16)
e.PublicKey.Curve = secp256k1.S256() e.PublicKey.X, e.PublicKey.Y =
e.PublicKey.Curve.ScalarBaseMult(e.D.Bytes()) return fmt.Sprintf("%x",
elliptic.MarshalCompressed(secp256k1.S256(), e.X, e.Y)) }
func main() { count, one := big.NewInt(1), big.NewInt(1)
count.SetString("9404625697166532776746648320380374280100293470930272690489102837043110636674",10)
PrivateKey := make([]byte, 32)
for { count.Add(count, one) copy(PrivateKey[32-len(count.Bytes()):],
count.Bytes()) fmt.Printf("%x\n",Public(PrivateKey)) } }
_______________________________________________________________________________________
output: ./ keysgo.go: 33: 33: unable to use PrivateKey (type [] byte) as
type string in argument in Public

I hope for your help. A thousand thanks
