∟Import Private Key to "geth" Account

This section describes how to import a private key from MetaMask wallet to a 'geth' account.

With the private key exported from my MetaMask wallet, I want to import it my "geth" account before I destroy MetaMask wallet.

1. Insert the memory stick that has the private key file.

2. Run "geth account import" command in a command window:

C:\> \herong\bin\geth --datadir \herong\Ethereum\personal 
   account import "E:\MetaMask Herong's Wallet Private Key"
   
Your new account is locked with a password. Please give a password. 
Do not forget this password.
Passphrase: ******
Repeat passphrase: ******
Address: {ef6ea9f8bd78ac42fb2617ba90846d5785bb320c}

Good. The MetaMask account is restored on the "geth" node now. The account address (the public key) is calculated correctly.

3. Check Account balance on "geth" console:

> eth.accounts
["0x05d4e1a499775ce9d681abd50bda655c7b5ccb90", 
 "0x485410d2e7b8bfb6f78e5e5acf7d1057cb853fce", 
 "0xef6ea9f8bd78ac42fb2617ba90846d5785bb320c"]

> third = eth.accounts[2]
"0xef6ea9f8bd78ac42fb2617ba90846d5785bb320c"

> eth.getBalance(third)
97999979000000000000

> web3.fromWei(eth.getBalance(third),"ether")
97.999979
