About gokey
gokey is a vaultless password and key generator written in Go that derives passwords and cryptographic private keys on demand from a master password or a seed file instead of storing them in a vault, aimed at developers and system administrators who want deterministic credentials available anywhere without managing, backing up, or syncing a password store.
