generate eos keys from Mnemonic/Seed

Question

I use this way to generate eos keys:

const hdkey = require('hdkey')
const wif = require('wif')
const ecc = require('eosjs-ecc')
const bip39 = require('bip39')
const mnemonic = 'real flame win provide layer trigger soda erode upset rate beef wrist fame design merit'
const seed = bip39.mnemonicToSeedHex(mnemonic)
const master = hdkey.fromMasterSeed(Buffer(seed, 'hex'))
const node = master.derive("m/44'/194'/0'/0/0")
console.log("publicKey: "+ecc.PublicKey(node._publicKey).toString())
console.log("privateKey: "+wif.encode(128, node._privateKey, false))

result:

publicKey: EOS61oRAVkx1rqPM8mEsBZxPAFAa9Nm6kLa7mQs6mRKTsRTFQaad7
privateKey: 5KX4T16FtxG9LvRJukA31TP9BKq3jYve3xQ3Px3ui8mzuJ7nUYE

With the new keys,I will update the EOS public key mapping to my Ethereum Wallet following this article.

So my question is, what different between this way and EOS Token Generator?

Answer 1

Mnemonic is a standard of bip39 for you to manage all chain private keys with a single master seed, so it's just a method to generate the private key, you can specify any private key you'd like if you don't want to use that standard.

Answer 2

What do you mean by "what is different"? The process you described above is correct for generating the EOS pub/priv key pair.

As for the site you linked, it appears they are using https://github.com/EOSIO/eosjs-ecc for the generation, which should provide the same/similar results.
