2023/05/15 19:15:59 gob: type elliptic.p256Curve has no exported fields

that appears when trying to create a wallet

I supposed it could be the go version. can you specify which version you use to create it

What I have done for fix the problem.
Modify wallet.go

type Wallet struct {
	PrivateKeyD []byte
	PublicKey  []byte
}

func NewKeyPair() (*big.Int, []byte) {
	curve := elliptic.P256()

	private, err := ecdsa.GenerateKey(curve, rand.Reader)
	if err != nil {
		log.Panic(err)
	}

	pub := append(private.PublicKey.X.Bytes(), private.PublicKey.Y.Bytes()...)
	return private.D, pub
}

func MakeWallet() *Wallet {
	privateD, public := NewKeyPair()
	wallet := Wallet{privateD.Bytes(), public}

	return &wallet
}

func (w *Wallet) GetPrivateKey() *ecdsa.PrivateKey {
	d := new(big.Int).SetBytes(w.PrivateKeyD)
	curve := elliptic.P256()

	priv := &ecdsa.PrivateKey{
		PublicKey: ecdsa.PublicKey{
			Curve: curve,
			X:     nil,
			Y:     nil,
		},
		D: d,
	}

	return priv
}

But the private key is not encrypted
