What is @ethersproject/json-wallets?
@ethersproject/json-wallets is a part of the ethers.js library, which provides utilities for handling JSON wallets. JSON wallets are a common format for storing Ethereum private keys in a secure, encrypted manner. This package allows you to create, encrypt, decrypt, and manage these wallets.
What are @ethersproject/json-wallets's main functionalities?
Creating a JSON Wallet
This feature allows you to create a new Ethereum wallet and encrypt it into a JSON format using a password.
const { Wallet } = require('@ethersproject/wallet');
const { save } = require('@ethersproject/json-wallets');
async function createJsonWallet(password) {
const wallet = Wallet.createRandom();
const json = await wallet.encrypt(password);
console.log(json);
}
createJsonWallet('your-password');
Decrypting a JSON Wallet
This feature allows you to decrypt an existing JSON wallet using the password it was encrypted with, and access the wallet's address and other properties.
const { Wallet } = require('@ethersproject/wallet');
const { fromEncryptedJson } = require('@ethersproject/json-wallets');
async function decryptJsonWallet(json, password) {
const wallet = await Wallet.fromEncryptedJson(json, password);
console.log(wallet.address);
}
decryptJsonWallet('your-json-wallet', 'your-password');
Saving a JSON Wallet to a File
This feature allows you to create a new JSON wallet and save it to a file for later use.
const { Wallet } = require('@ethersproject/wallet');
const { save } = require('@ethersproject/json-wallets');
const fs = require('fs');
async function saveJsonWalletToFile(password, filePath) {
const wallet = Wallet.createRandom();
const json = await wallet.encrypt(password);
fs.writeFileSync(filePath, json);
}
saveJsonWalletToFile('your-password', 'wallet.json');
