Golang keystore.Store类代码示例

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Golang中github.com/btcsuite/btcwallet/internal/legacy/keystore.Store的典型用法代码示例。如果您正苦于以下问题:Golang Store类的具体用法?Golang Store怎么用?Golang Store使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



在下文中一共展示了Store类的4个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: PrivatePass

// PrivatePass prompts the user for a private passphrase with varying behavior
// depending on whether the passed legacy keystore exists.  When it does, the
// user is prompted for the existing passphrase which is then used to unlock it.
// On the other hand, when the legacy keystore is nil, the user is prompted for
// a new private passphrase.  All prompts are repeated until the user enters a
// valid response.
func PrivatePass(reader *bufio.Reader, legacyKeyStore *keystore.Store) ([]byte, error) {
	// When there is not an existing legacy wallet, simply prompt the user
	// for a new private passphase and return it.
	if legacyKeyStore == nil {
		return promptPass(reader, "Enter the private "+
			"passphrase for your new wallet", true)
	}

	// At this point, there is an existing legacy wallet, so prompt the user
	// for the existing private passphrase and ensure it properly unlocks
	// the legacy wallet so all of the addresses can later be imported.
	fmt.Println("You have an existing legacy wallet.  All addresses from " +
		"your existing legacy wallet will be imported into the new " +
		"wallet format.")
	for {
		privPass, err := promptPass(reader, "Enter the private "+
			"passphrase for your existing wallet", false)
		if err != nil {
			return nil, err
		}

		// Keep prompting the user until the passphrase is correct.
		if err := legacyKeyStore.Unlock([]byte(privPass)); err != nil {
			if err == keystore.ErrWrongPassphrase {
				fmt.Println(err)
				continue
			}

			return nil, err
		}

		return privPass, nil
	}
}

示例2: convertLegacyKeystore

// convertLegacyKeystore converts all of the addresses in the passed legacy
// key store to the new waddrmgr.Manager format.  Both the legacy keystore and
// the new manager must be unlocked.
func convertLegacyKeystore(legacyKeyStore *keystore.Store, manager *waddrmgr.Manager) error {
	netParams := legacyKeyStore.Net()
	blockStamp := waddrmgr.BlockStamp{
		Height: 0,
		Hash:   *netParams.GenesisHash,
	}
	for _, walletAddr := range legacyKeyStore.ActiveAddresses() {
		switch addr := walletAddr.(type) {
		case keystore.PubKeyAddress:
			privKey, err := addr.PrivKey()
			if err != nil {
				fmt.Printf("WARN: Failed to obtain private key "+
					"for address %v: %v\n", addr.Address(),
					err)
				continue
			}

			wif, err := btcutil.NewWIF((*btcec.PrivateKey)(privKey),
				netParams, addr.Compressed())
			if err != nil {
				fmt.Printf("WARN: Failed to create wallet "+
					"import format for address %v: %v\n",
					addr.Address(), err)
				continue
			}

			_, err = manager.ImportPrivateKey(wif, &blockStamp)
			if err != nil {
				fmt.Printf("WARN: Failed to import private "+
					"key for address %v: %v\n",
					addr.Address(), err)
				continue
			}

		case keystore.ScriptAddress:
			_, err := manager.ImportScript(addr.Script(), &blockStamp)
			if err != nil {
				fmt.Printf("WARN: Failed to import "+
					"pay-to-script-hash script for "+
					"address %v: %v\n", addr.Address(), err)
				continue
			}

		default:
			fmt.Printf("WARN: Skipping unrecognized legacy "+
				"keystore type: %T\n", addr)
			continue
		}
