# Keyring

The private and public keys users use to interact with nodes are stored in the keyring. You can import, export, and delete keys using the keyring command line interface. A case study would be when a validator key needs to be set up before running the blockchain node; the keyring would be resourceful in correctly signing the block. 

The private key can be stored in different locations, called "backends", such as the operating system's own key storage or any file that supports it, such as a password manager or wallet manager like [KDE Wallet Manager](https://docs.kde.org/stable5/en/kwalletmanager/kwallet5/).
