_Follow along with this video:_ --- ### Meanwhile, some things have changed In our previous lesson, we showed you how to configure and use a `.env` file to hold your private key and rpc url, some developments have taken place since that lesson was made so ... You should never use a `.env` again. ### Encrypting your Keys Using ERC2335 For now, let's pretend our private key is this: `0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80` (key 0 from Anvil) Type the following command in your terminal: ``` cast wallet import nameOfAccountGoesHere --interactive ``` Ideally, you don't do this in your VS Code. You will be asked for your private key and a password to secure it. You will do this only once, which is amazing! If you remember, last lesson we deployed running the following command: ``` forge script script/DeploySimpleStorage.s.sol --rpc-url $RPC_URL --broadcast --private-key $PRIVATE_KEY ``` Now that we configured our wallet we can deploy as following: ``` forge script script/DeploySimpleStorage.s.sol --rpc-url http://127.0.0.1:8545 --broadcast --account nameOfAccountGoesHere --sender 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266 ``` You will be asked for your password. You won't be able to deploy without your password. To see all the configured wallets you can call the following: `cast wallet list`. Clear your history so your private key won't randomly remain there using the following command: `history -c`. ***Stay safe! Stay froggy! Don't lose your keys. If you are seeing your private key in plain text, you are doing something wrong.***
