开源项目的地址：https://github.com/guoshijiang/blockchain-wallet-sdk/

可以看得出来，该项目仍在更新代码中，目前助记词和keystore部分的代码已经完成，下面咱们就来就SDK中的助记词生成部分进行简单的使用：

一.助记词

目前支持生成12,15,18,21,24个不同语言的助记词，支持的语言有中文简体，中文繁体，英语，法语，日语，意大利语，韩语和西班牙语。库中也提供助记词的编解码和随机数种子的生成。

1.助记词生成

使用该库前需要先引入库

var testWord = require("../sdk/mnemonic/generateWord");

下面简单地写几个案例

1.1.生成12个中文简体助记词

var chinese_simplified = testWord.createHelpWord(12, 'chinese_simplified');

侧 钟 毕 蓝 祝 牢 炭 旬 岛 锦 裁 萧

1.2.生成15个中文繁体助记词

var words = testWord.createHelpWord(15, 'chinese_traditional');

晚 錢 破 性 及 普 木 迷 矛 而 肅 揭 聖 擠 言

1.3.生成18个日文助记词

var words = testWord.createHelpWord(18, 'japanese');

かくとく　たもつ　けっせき　ちたい　こんわく　ぐっすり　しちょう　たいふう　まける　しほん　にんそう　てくび　さつまいも　ちつじょ　だいじょうぶ　ひっこし　てんらんかい　むかい

*注：您要生成多少个助记词，您就传入数字几（目前支持：12,15,18,21,24）；后面一个传入相应的语言，目前可以传入的语言有：chinese_simplified（中文简体）；chinese_traditional（中文繁体）；english（英语）；french（法语）；italian（意大利语）；japanese（日语）；korean（韩语）；spanish（西班牙语）。

2.助记词编解码

// 生成助记词
var words = testWord.createHelpWord(18, 'japanese');
console.log(words)

// 助词编码
var wordsEntropy = testWord.wordsToEntropy(words, 'japanese');
console.log(wordsEntropy);

// 助记词解码
var wd = testWord.entropyToWords(wordsEntropy, 'japanese');
console.log(wd);

3.验证助记词

var bool = testWord.validateMnemonic(words, 'japanese');
console.log(bool)  // 返回true表示验证成功

二.生成地址

目前该库支持以太坊，ERC20和比特币地址和私钥生成

1.生成BTC地址

下面代码是生成比特地址的代码

var mnemonicS = require("../sdk/mnemonic/generateWord");
var address = require("../sdk/address/generateAddress");

var mnemonic= mnemonicS.createHelpWord(12, 'english');
var seed = mnemonicS.mnemonicToSeed(mnemonic);
var addressParmas = {
    "seed":seed,
    "coinType":"BTC",
    "number":"12",
    "bipNumber":"0",
    "receiveOrChange":"1",
    "coinMark":"BTC"
}

var addr = address.blockchainAddress(addressParmas);
console.log(addr);

下面是生成效果：

{ 
  coinMark: 'BTC',
  privateKey: 'L3LK2uQQZCj7x7SzGSyRbiP8RwrYpGFPw7qbjuMKNfz83edmMJG3',
  address: '1AtMVGqbVSZDc4p5H414Q8zKqXMoYv7zxs' 
}

上述代码中参数seed是随机数种子，这里需要传入的是一个Buffer流；coinType是要生成地址的币的类别，目前支持三种传参方式：BTC，ETH和ERC20;number是要生成第几个地址，0默认是第一个；bipNumber是该要生成地址的币在BIP44协议中的规范数字；receiveOrChange是比特币地址生成专用参数，0代表普通地址，1代表找零地址；coinMark是币的标识，例如bitcoin的标识是BTC，ethereum的标识是ETH。

2.生成以太坊地址

下面是生成以太坊地址的代码，参数如上

var mnemonicS = require("../sdk/mnemonic/generateWord");
var address = require("../sdk/address/generateAddress");

var mnemonic= mnemonicS.createHelpWord(12, 'english');
var seed = mnemonicS.mnemonicToSeed(mnemonic);
var addressParmas = {
    "seed":seed,
    "coinType":"ETH",
    "number":"0",
    "bipNumber":"60",
    "receiveOrChange":"1",
    "coinMark":"ETH"
}

var addr = address.blockchainAddress(addressParmas);
console.log(addr);

生成效果

{ 
      coinMark: 'ETH',
      privateKey: '612c02325cbf84cd4ad3dac8ae107e2bf37f98834b23f6f6208547f1a179d852',
      address: '0x947ee95a84f9bdf00dbc600961a737cb92fca5f4' 
}

仔细观看不难看出，上面地址生成中，主要是参数改变了

3.生成单个ERC20地址

下面是生成ERC20地址的代码，参数如上

var mnemonicS = require("../sdk/mnemonic/generateWord");
var address = require("../sdk/address/generateAddress");

var mnemonic= mnemonicS.createHelpWord(12, 'english');
var seed = mnemonicS.mnemonicToSeed(mnemonic);
var addressParmas = {
    "seed":seed,
    "coinType":"ERC20",
    "number":"0",
    "bipNumber":"518",
    "receiveOrChange":"1",
    "coinMark":"LET"
}

var addr = address.blockchainAddress(addressParmas);
console.log(addr);

也只是传入参数发生变化

生成效果：

{ 
      coinMark: 'LET',
      privateKey: '0bdf145ae58a71c0da7fc3cf5510de5909d1314722f8d90c6b9ee543e431f1c7',
      address: '0x7d0c60a5ef87ed7f43fcad648911327c1f474623' 
}

4.批量生成ERC20地址

var mnemonicS = require("../sdk/mnemonic/generateWord");
var address = require("../sdk/address/generateAddress");

var mnemonic= mnemonicS.createHelpWord(12, 'english');
var seed = mnemonicS.mnemonicToSeed(mnemonic);

var ERC20AddressParam = {
    "seed":seed,
    "erc20":[
        {
            "coinMark":"LET",
            "bipNumber":"618",
            "number":"0"
        },{
            "coinMark":"SSP",
            "bipNumber":"518",
            "number":"0"
        },{
            "coinMark":"Kcash",
            "bipNumber":"128",
            "number":"0"
        }
    ]
}

var addre= address.multiERC20AddressGenerate(ERC20AddressParam);
console.log(addre);

如下是生成的效果

[ 
      {
            coinMark: 'LET',
            privateKey: '164a6167e4c50e24ad6a74fd1cab6521e3a1472a70d67c88146a1952b7fb5092',
            address: '0x3a960d90b219ea4b9d3f5827ea6fba5bf40d391f' 
     },
     { 
            coinMark: 'SSP',
            privateKey: 'f8f766b246289f325e32cb28462096ade51f89b720dc6b064168baef2e6c9ac4',
            address: '0x8f5589faf64374788d1c8f3b1744bad1627ec565'
     },
     { 
            coinMark: 'Kcash',
            privateKey: '9bf8d4b890b391736cec94220d5d41d0c8a2b9555a5385316eecbeb89ce37d61',
            address: '0x910b0d94dd1f0f173f41e5ed0a2ddefeea6b4130' 
    } 
]

三.以太坊Keystore

1.生成Keystore

生成keystore的只需要传入密码，将自动生成keystore,下面函数中只需要传入一个参数，那就密码。“123456”就是传入的密码。

var testKeystore = require("../sdk/keystore/generateKeystore");
var keystore = testKeystore.createKeystore("123456");
console.log(keystore);


{ 
      address: '531fe5d8be925ceba9bfce0c305d93fc6deb862b',
      crypto:
      { 
            cipher: 'aes-128-ctr',
            ciphertext: '3cf8ba317042815338f7397d80a53cf84cc7861c9ce70ed26fd23b2fdab9efc',
            cipherparams: { iv: '82c3b2d97f65ff974563bd14d5edaf4f' },
            mac: '67b2960dd73cd4f35d375a4c8c0898fc6f6cd9b7190dafb1c14aa724179a1e06',
            kdf: 'pbkdf2',
            kdfparams:
            { 
                  c: 262144,
                  dklen: 32,
                  prf: 'hmac-sha256',
                  salt: 'cb7a82cba06330ffe0ad2fea7124034d53f5db559e30e7752f9562dab8caa39c
             } 
       },
      id: 'a101bdc9-54d6-44a9-b787-587c92fbc680',
      version: 3
}

2.导出keystore

exportKeystore是导出Keystore的函数，需要传入的参数是密码和路径，返回keystore的值

var testKeystore = require("../sdk/keystore/generateKeystore");

var keystore = testKeystore.createKeystore("123456");
console.log(keystore);
testKeystore.exportKeystore(keystore, "./");

在你指定的目录下会生成相应的keystore文件

3.导入keystore

var keystore = testKeystore.importKeystore("531fe5d8be925ceba9bfce0c305d93fc6deb862b", "./");
console.log(keystore);

{ 
      address: '531fe5d8be925ceba9bfce0c305d93fc6deb862b',
      crypto:
      { 
            cipher: 'aes-128-ctr',
            ciphertext: '3cf8ba317042815338f7397d80a53cf84cc7861c9ce70ed26fd23b2fdab9efc',
            cipherparams: { iv: '82c3b2d97f65ff974563bd14d5edaf4f' },
            mac: '67b2960dd73cd4f35d375a4c8c0898fc6f6cd9b7190dafb1c14aa724179a1e06',
            kdf: 'pbkdf2',
            kdfparams:
            { 
                  c: 262144,
                  dklen: 32,
                  prf: 'hmac-sha256',
                  salt: 'cb7a82cba06330ffe0ad2fea7124034d53f5db559e30e7752f9562dab8caa39c
             } 
       },
      id: 'a101bdc9-54d6-44a9-b787-587c92fbc680',
      version: 3
}

4.导出私钥

var privateKey = testKeystore.exportPrivateKey(keystore, "123456")

5.导入私钥

 var keystore = testKeystore.importPrivateKey("qeeqeqqeqwweq", "123456");
 console.log(keystore)

 { address: '805a06621171443bcf7d2bae9ac4c91539aef65f',
  crypto:
   { cipher: 'aes-128-ctr',
     ciphertext: 'f7c0ce4b3c83b9927ce75cbceb',
     cipherparams: { iv: '173ecf2cf4e34879175190a5a7b328cd' },
     mac: 'd8b829e98383cbc8eb69f090e765c085e0882006489c74837aa4bff69b7b62bc',
     kdf: 'pbkdf2',
     kdfparams:
      { c: 262144,
        dklen: 32,
        prf: 'hmac-sha256',
        salt: '85766bde5af062f631d62d16842d079e8a0a52a0555bfd94ce3f1b3c28fa839b'
 } },
  id: '70860efe-84f0-43c9-9d68-3f8f0262203b',
  version: 3 }

四.数字货币签名

1.比特币单笔转账签名

const testBtcSign = require('../sdk/sign/bitcoinSign');

var privateKey  = "L2CzLwNmNxVtV4RpgBMMRKPWhZmDeMofqxEqUjeRi8nQaVae5F51";
var amount = "100000";
var utxo = {
    "unspent_outputs":[
        {
            "tx_hash":"8ee886ba0c66ba2df2c0e3da3beee526996d9a5e6bbbdfea43e1a78340cb0128",
            "tx_hash_big_endian":"2801cb4083a7e143eadfbb6b5e9a6d9926e5ee3bdae3c0f22dba660cba86e88e",
            "tx_index":382253932,
            "tx_output_n": 0,
            "script":"76a914ca45c6eceea7aed14b6aea7e0ed466c6134f14bc88ac",
            "value": 1899000,
            "value_hex": "1cf9f8",
            "confirmations":2
        }
    ]
};
var sendFee = "100000";
var toAddress = "12zEJohMNqSZLXH1Msxpw41ykkk3rxgx1s";
var changeAddress = "12zEJohMNqSZLXH1Msxpw41ykkk3rxgx1s";

var signValue = testBtcSign.btcSingleSign(privateKey, amount, utxo.unspent_outputs, sendFee, toAddress, changeAddress);
console.log(signValue);

结果如下：

            "amount":10
        }
    ]
}

var bitUtxo = {
    "unspent_outputs":[
        {
            "tx_hash":"8ee886ba0c66ba2df2c0e3da3beee526996d9a5e6bbbdfea43e1a78340cb0128",
            "tx_hash_big_endian":"2801cb4083a7e143eadfbb6b5e9a6d9926e5ee3bdae3c0f22dba660cba86e88e",

            "value_hex": "1cf9f8",
            "confirmations":2
        }
    ]
};

var utxo = bitUtxo.unspent_outputs;
var signValue = testBtcSign.btcMultiSign(sendInfo, utxo);
console.log(signValue);

结果：

4.以太坊批量转账签名

const testEthSign = require('../sdk/sign/ethereumSign');

var sendData =
    {
        "signMark":"ETH",
        "privateKey":"a2506976294fc506f6969e8f914ae9371804b104163f07e8d0e96794d5b43189",

5.ERC20单笔转账签名

const testERC20Sign = require('../sdk/sign/erc20Sign');

var privateKey = "a2506976294fc506f6969e8f914ae9371804b104163f07e8d0e96794d5b43189";
var nonce = 78;
var currentAccount = "0xc6328b3a137b3be3f01c35ecda4ecda375be7fdf";
var contractAddress = "0xfa3118b34522580c35ae27f6cf52da1dbb756288";
var toAddress = "0xe558be4e90b2ac96ae5cad47dc39cd08316f2e57";
var gasPrice = 9000000000;
var gasLimit = 120000;
var totalAmount = 10;
var decimal = 6;

var signValue = testERC20Sign.ethereumErc20CoinSign(privateKey, nonce, currentAccount, contractAddress, toAddress,  gasPrice,  gasLimit, totalAmount, decimal);
console.log(signValue);

结果：
