當麻許的超技八

最近在搞事情，然後遇到一個之前我沒有發現的問題，以前在產生錢包的時候，我以為只要符合 BIP39 規範任選 12 or 24 單字就可以了

事實上，如果當你要把這隨便亂取的 12 的單字放入 MetaMask 或是其他 Web3 錢包的時候，就會出現

因為我之前測試都是使用 cat 重複 12 次，後來研究 一下才知道，原來最後一個單字是一個 驗證的動作，所以沒有過的原因是因為最後一個字不對

最後一個字，會取決於你前面11個字，所以不是每個字都是可以用的，如果你是用 12 個單字的助記詞，則最後一個單字應該會有 128 個可能

其實在程式上面是沒有阻擋你最後一個單字，但是現在 MetaMask 還有 其他 Web3 或是硬體錢包都有阻擋，所以你還是得按照規則來

今天就延續這一篇 Ethereum 以太坊產生高清錢包 (HD Wallet) 繼續寫 

1. 安裝 Nethereum.HdWallet

2. 因為其實可以不用去理解它的原理直接用列舉法把所有的  wordlist 撈出來 加入比對即可
