在手机钱包 app 里可以选择通过助记词导入钱包。

不过星云的 Web 钱包在帮你生成钱包地址时并不会提供助记词,只会提供 keystore。你可以通过 keystore 在手机钱包 App 中导入你的钱包。

注意:助记词可以还原出你的私钥,所以不要泄漏你的助记词。


关于助记词,可以参考这篇文章:

还有一个大家使用钱包中经常遇到的,就是钱包帮你生成一串12个单词的句子,让你把这个句子抄下来保存好。比如这样的:

voice again pupil thumb strategy toss extend unusual neutral shuffle claim cave

这是什么呢?和私钥又是什么关系呢?

它叫助记词(mnemonic code),其实就跟以前地下工作者用的密码本一样,也跟“A for alpha, B for Brave, C for Charlie ”的原理类似。,BIP39(Bitcoin Improvement Proposal 39)定义了2048个单词的列表,每个单词都有编号,比如

voice ==>1964
again ==> 38
...
cave ==> 295

然后把这些数字按照一些复杂的算法拼起来就可以还原出来私钥了。
