[Go] How do I convert a public key to an account hash?

In the Casper network, wallets are tied to account hashes, which can be derived from a public key hex. You can only convert a public key to an account hash, you cannot get a public key from an account hash. The network does not support this conversion.

To convert a public key to an account hash in the Casper Go SDK, you will need to use the following code:

package main

import (
	"encoding/hex"
	"fmt"

	"github.com/casper-ecosystem/casper-go-sdk/crypto"
)

func main() {
	publicKeyHex := "0119bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1"

	publicKeyBytes, err := hex.DecodeString(publicKeyHex)
	if err != nil {
		panic(err)
	}

	publicKey, err := crypto.NewPublicKey(publicKeyBytes)
	if err != nil {
		panic(err)
	}

	accountHash := publicKey.ToAccountHash()

	fmt.Printf("Account hash: %s\n", accountHash.String())
}

This code uses the crypto package from the Casper Go SDK to create a public key object from the provided public key hex. Then, it converts the public key object to an account hash using the ToAccountHash() method. Finally, it prints the resulting account hash.
