Solana blockchain. How can i generate private key?

Question

       const solanaWeb3 = require("@solana/web3.js");
    const solanatoken = require("@solana/spl-token");
    
      var wallet = solanaWeb3.Keypair.generate();
      console.log("public key...", wallet.publicKey);
      console.log("secret key...", wallet.secretKey);
    
      console.log("secret key...", JSON.stringify(wallet.secretKey.toString()));`enter preformatted text here`

I got

public key... PublicKey {
  _bn: <BN: b5ec974285759f4004555c6890e045a4ce857c6a056895d77dd209c054e76556>
secret key... "211,55,244,72,160,174,33,152,24,226,97,172,91,91,47,3,148,83,99,188,150,111,153,248,253,237,31,223,194,194,199,0,181,236,151,66,133,117,159,64,4,85,92,104,144,224,69,164,206,133,124,106,5,104,149,215,125,210,9,192,84,231,101,86"

how I can get private key , like

kNykCXNxgePDjFbDWjPNvXQRa8U12Ywc19dFVaQ7tebUj3m7H4sF4KKdJwM7yxxb3rqxchdjezX9Szh8bLcQAjb

for use on the phantom wallet? docs: https://solana-labs.github.io/solana-web3.js/classes/Keypair.html

Answer 1

If you want the private key in base58, you'll have to do a conversion.

wallet.secretKey gives a Uint8Array : https://solana-labs.github.io/solana-web3.js/classes/Keypair.html#secretKey , so you'll have to convert from Uint8Array to a base58 string.

There are packages to do that, and Solana's web3 package uses bs58 : https://github.com/cryptocoinjs/bs58#encodeinput

So you'll have to do bs58.encode(wallet.secretKey) to get the string as you're expecting.

Answer 2

要在幻影钱包上使用，您可以直接复制和粘贴字节数组。

Answer 3

您可以使用 bs58() 或 PublicKeycode.en 将 UInt8Array 更改为字符串，例如“kNykCXNxgePDjFbDWjPNvXQRa8U12Ywc19dFVaQ7tebUj3m7H4sF4KKdJwM7yxxb3rqxchdjezX9Szh8bLcQAjb”。

let secretKey = keyPair.secretKey.toBase58();
