Transforms a passphrase into a valid Ethereum/BSC/Polygon/... wallet
It uses the SHA256 Hash function to derivate private key from passphrase.
I needed a way to regain access to my wallets without depending on any physical instrument.
npm install -g ethbrain
Options:
-p Show private key in hex format.
-q Show private key QR code.
--help, -h Show help.
Usage example:
ethbrain -p -q #Show private key in hex format and QR code.
