Icon LinkEncrypting and storing wallets

Icon LinkCreating a wallet and storing an encrypted JSON wallet on disk

You can also manage a wallet using JSON wallets Icon Link that are securely encrypted and stored on the disk. This makes it easier to manage multiple wallets, especially for testing purposes.
You can create a random wallet and, at the same time, encrypt and store it. Then, later, you can recover the wallet if you know the master password: 
use fuels::prelude::*;
 
let dir = std::env::temp_dir();
let mut rng = rand::thread_rng();
 
// Use the test helper to setup a test provider.
let provider = setup_test_provider(vec![], vec![], None, None).await?;
 
let password = "my_master_password";
 
// Create a wallet to be stored in the keystore.
let (_wallet, uuid) =
    WalletUnlocked::new_from_keystore(&dir, &mut rng, password, Some(provider.clone()))?;
 
let path = dir.join(uuid);
 
let _recovered_wallet = WalletUnlocked::load_keystore(path, password, Some(provider))?;

Icon LinkEncrypting and storing a wallet created from a mnemonic or private key

If you have already created a wallet using a mnemonic phrase or a private key, you can also encrypt it and save it to disk: 
use fuels::prelude::*;
 
let dir = std::env::temp_dir();
 
let phrase =
    "oblige salon price punch saddle immune slogan rare snap desert retire surprise";
 
// Use the test helper to setup a test provider.
let provider = setup_test_provider(vec![], vec![], None, None).await?;
 
// Create first account from mnemonic phrase.
let wallet = WalletUnlocked::new_from_mnemonic_phrase(phrase, Some(provider))?;
 
let password = "my_master_password";
 
// Encrypts and stores it on disk. Can be recovered using `Wallet::load_keystore`.
let _uuid = wallet.encrypt(&dir, password)?;
