USAGE

extern crate ethereum_key;
use ethereum_key::Band;
// <- Keypair && Phrase ->
let band: Band = Band::generate();
println!("phrase:  {:?}", &band.phrase);
println!("secret:  {:?}", &band.secret);
println!("public:  {:?}", &band.public);
println!("address: {:?}", &band.address);
// phrase:  "reborn chair modular immunize handshake sampling moody outburst grower sweat clique affront"
// secret:  0x779ff5fe168de6560e95dff8c91d3af4c45ad1b261d03d22e2e1558fb27ea450
// public:  0xa90b7d1953d7462fa8e9d510dbb7aeb081606ef9d7f3fb0c2dd3666f84c9917e61a6c4bfa0483050be0bb6d650530c02263b6fcd092e0536a909cbb222d7c4c7
// address: 0x00be8153c55276be0b27e9f66db523f2f17cc783
// <- Generate from phrase of secret ->
let phrase: String = "hemstitch remover province donated outing oversized playoff outshoot trowel wimp palm flashily"
let secret: String = "26d1ec50b4e62c1d1a40d16e7cacc6a6580757d5"
let band2: Band = Band::from(phrase);
let band3: Band = Band::from(secret);

BIPs

BIP32: Hierarchical Deterministic wallet, 从单一 seed 产生树状结构存储多组 keypairs (私钥和公钥)。可以方便的备份、转移到其他相容装置，以及分层权限控制。

BIP39: 将 seed 方便记忆和书写的单字表示。一般由12个单字组成，称为 mnemonic code(phrase), 中文成为助记词和助记码。例如:

rose rocket invest real refuse margin festival danger anger border idle brown

BIP44: 基于 BIP32 的系统，赋予树状结构中的各层特殊的意义。让同一个 seed 可以支援多币种、多账户等。各层定义如下:

m / purpose' / coin_type' / account' / change / address_index

Ethereum HD wallet:
Ethereum 的钱包目前均采用以上 Bitcoin HD Wallet 的架构，并订 coin_type 为 60'。在一个 Ethereum HD Wallet 中，第一个账户(这里的账户是指 BIP44 中定义的 account) 的第一组 keypair, 其路径会是 m/44'/60'/0'/0/0。
