Usage: vault operator unseal [options] [KEY]
|
|
|
|
Provide a portion of the master key to unseal a Vault server. Vault starts
|
|
in a sealed state. It cannot perform operations until it is unsealed. This
|
|
command accepts a portion of the master key (an "unseal key").
|
|
|
|
The unseal key can be supplied as an argument to the command, but this is
|
|
not recommended as the unseal key will be available in your history:
|
|
|
|
$ vault operator unseal IXyR0OJnSFobekZMMCKCoVEpT7wI6l+USMzE3IcyDyo=
|
|
|
|
Instead, run the command with no arguments and it will prompt for the key:
|
|
|
|
$ vault operator unseal
|
|
Key (will be hidden): IXyR0OJnSFobekZMMCKCoVEpT7wI6l+USMzE3IcyDyo=
