如何使用 web3 创建私钥和公钥？

Question

I want to create a private key and public key, basically a new account in Ethereum using web3. But I want to generate a private key that is 32 bytes in length. Does anyone know how to generate the same? Used the following code, but not able to generate a 32 bytes long private key.

 web3.eth.accounts.create();

Answer 1

Ethereum uses 32 bytes (which is 64 hex characters) long private keys.

You can access the private key generated using the accounts.create() method ( docs ) in the privateKey property.

const account = web3.eth.accounts.create();
console.log(account.privateKey);

Answer 2

 web3.eth.accounts.create() address: '0xB9b1415Dbd1B3C9a5890433DF8B2b389445CC6Fa', privateKey: '0x498262a4afde2bdd9e1bef3aafc6442ec36ccf167e527457a211118de93346ba', signTransaction: [Function: signTransaction], sign: [Function: sign], encrypt: [Function: encrypt]

the private key is here '0x498262a4afde2bdd9e1bef3aafc6442ec36ccf167e527457a211118de93346ba' this is of a 64 hex format.

so the 32 bytes length private key is 498262a4afde2bdd9e1bef3aafc6442ec36ccf167e527457a211118de93346ba

(remove the 0x )
