How to encrypt & decrypt a wallet?

[adriandelgg]

Hi, in Web3.js there are 2 methods that allow you to encrypt and decrypt a wallet so that you can use them to create a wallet app.

web3.eth.accounts.wallet.encrypt(password);
web3.eth.accounts.wallet.decrypt(keystoreArray, password);

How can I do the same thing with Ethers?

1. If I'm building a wallet app like MetaMask, how can I make it so a user inputs a password to encrypt and decrypt the wallet?

2. How can I create a brand new ETH account using Ethers.js?

All the methods you are looking for are documented here: https://docs.ethers.io/v5/api/signer/#Wallet

The createRandom() creates a new wallet, and there are various encrypting and decrypting options depending if you want sync or async; you will generally want to use the async methods, which allow a callback to update a progress bar.

Let me know if you have any issues. :)

Thank you, Richard!
So in order to decrypt, I would use ethers.Wallet.fromEncryptedJson()?

I guess I got a little confused since I was looking for the work decrypt like in Web3.js

[ricmoo]

Yes, that’s the method you want. :)

(I should prolly include the word decrypt in the docs so search works)

[adriandelgg]

Yes, that would definitely be helpful since I was pretty lost trying to find it throughout the docs. I'm sure others may have experienced the same thing.

Nonetheless, it all works beautifully.

Thank you, Richard!👷
