Use: "keys",
Short: "Manage your application's keys",
Long: `Keyring management commands. 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. Refer to their respective documentation for more
information:
KWallet https://github.com/KDE/kwallet
pass https://www.passwordstore.org/
The pass backend requires GnuPG: https://gnupg.org/
