5.6.3. 从私钥导入以太坊地址

首先将私钥存储到文件中，然后导入，导入后需要输入密码。

			
[ethereum@netkiller ~]$ echo "f592b7bf06ca9fd7696ba95d6ed8e357de6a2379b6d5fe1ffd53c6b4b063cd4a" > privatekey
[ethereum@netkiller ~]$ geth account import privatekey
INFO [04-27|17:25:38] Maximum peer count                       ETH=25 LES=0 total=25

Passphrase:
Repeat passphrase:

查看导入文件

			
[ethereum@netkiller ~]$ ls .ethereum/keystore/*372fda02e8a1eca513f2ee5901dc55b8b5dd7411
.ethereum/keystore/UTC--2018-04-27T09-25-48.189741023Z--372fda02e8a1eca513f2ee5901dc55b8b5dd7411

[ethereum@netkiller ~]$ cat .ethereum/keystore/UTC--2018-04-27T09-25-48.189741023Z--372fda02e8a1eca513f2ee5901dc55b8b5dd7411

最后一定记得删除私钥问题，因为这个私钥没有加密过，一旦泄露后果不堪设想。

			
[ethereum@netkiller ~]$ rm -rf privatekey
			
			

如果不存储文件可以单行执行，然后删除 history 历史文件

			
[ethereum@netkiller ~]$ geth account import <(echo f592b7bf06ca9fd7696ba95d6ed8e357de6a2379b6d5fe1ffd53c6b4b063cd4a)
[ethereum@netkiller ~]$ >.bash_history
