go wallet

golang blockchain wallet wrapper

  • generate address, phrase, private key, public key
  • sign and verify message

example

import (
	"github.com/civet148/go-wallet"
	"github.com/civet148/log"
)

func main() {

    //create a new wallet
    var wc = wallet.NewWalletEthereum(wallet.OpType_Create)
    log.Infof("[CREATE] address [%s] private key [%s] public key [%s] phrase [%s]", wc.GetAddress(), wc.GetPrivateKey(), wc.GetPublicKey(), wc.GetPhrase())

    //recover a wallet from phrase
    var wr = wallet.NewWalletEthereum(wallet.OpType_Recover, wc.GetPhrase())
    log.Infof("[RECOVER] address [%s] private key [%s] public key [%s] phrase [%s]", wr.GetAddress(), wr.GetPrivateKey(), wr.GetPublicKey(), wr.GetPhrase())
    
    //load a wallet from full info
    var wl = wallet.NewWalletEthereum(wallet.OpType_Load, wc.GetAddress(), wc.GetPrivateKey(), wc.GetPublicKey(), wc.GetPhrase())
    log.Infof("[LOAD] address [%s] private key [%s] public key [%s] phrase [%s]", wl.GetAddress(), wl.GetPrivateKey(), wl.GetPublicKey(), wl.GetPhrase())
    
    //new a wallet from public key, you just can verify signature
    var wv = wallet.NewWalletEthereum(wallet.OpType_Verify, wc.GetPublicKey())
    log.Infof("[VERIFY] public key [%s]", wv.GetPublicKey())
    
    var strHelloWorld = "hello world"
    strSigned, err := wc.SignText([]byte(strHelloWorld))
    if err != nil {
        log.Errorf("sign failed [%s]", err.Error())
        panic(err.Error())
    }
    log.Infof("signature [%s]", strSigned)
    if !wv.VerifyText([]byte(strHelloWorld), strSigned) {
