Golang FromECDSA Examples

Example #1

File: key.go Project: expanse-project/go-expanse

func (k *Key) MarshalJSON() (j []byte, err error) {
	jStruct := plainKeyJSON{
		hex.EncodeToString(k.Address[:]),
		hex.EncodeToString(crypto.FromECDSA(k.PrivateKey)),
		k.Id.String(),
		version,
	}
	j, err = json.Marshal(jStruct)
	return j, err
}
