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/
