  }, function (err, ks) {
    // Some methods will require providing the `pwDerivedKey`,
    // Allowing you to only decrypt private keys on an as-needed basis.
    // You can generate that value with this convenient method:
    ks.keyFromPassword('xxxxxxxxxxxxxx<密码>', function (err, pwDerivedKey) {
      if (err) throw err
      // generate five new address/private key pairs
      // the corresponding private keys are also encrypted
      ks.generateNewAddress(pwDerivedKey, 1)
      address = ks.getAddresses()[0]
      console.log('0x'+address)  // 地址
      privateKey = ks.exportPrivateKey(address, pwDerivedKey)
      console.log('0x'+privateKey) // 私钥
      randomSeed = ks.getSeed(pwDerivedKey)
      console.log(randomSeed) // 助记词
      // Now set ks as transaction_signer in the hooked web3 provider
      // and you can start using web3 using the keys/addresses in ks!
