These keys may be in any format supported by the Tendermint crypto library and can be used by light-clients, full nodes, or any other application that needs to sign with a private key. The keyring supports the following backends: os Uses the operating system's default credentials store. file Uses encrypted file-based keystore within the app's configuration directory. This keyring will request a password each time it is accessed, which may occur multiple times in a single command resulting in repeated password prompts. kwallet Uses KDE Wallet Manager as a credentials management application. pass Uses the pass command line utility to store and retrieve keys. test Stores keys insecurely to disk. It does not prompt for a password to be unlocked and it should be use only for testing purposes. kwallet and pass backends depend on external tools.
