A small utility to create and restore Ethereum wallets offline. It uses ethers.js and node's native crypto library under the hood.
Install the package locally or globally:
npm install -g offline-wallets
To create a new wallet simply use ofwl create.
You can "restore" a wallet from a 24 word seedphrase and passcode with ofwl restore. If your wallet didn't use a passphrase leave it blank.
If you want to generate a random passphrase use ofwl passphrase 12. The number is optional and will default to 12. You can specify how many random bytes to generate.
