Usage: vault unseal [options] [key]
|
|
|
|
Unseal the vault by entering a portion of the master key. Once all
|
|
portions are entered, the Vault will be unsealed.
|
|
|
|
Every Vault server initially starts as sealed. It cannot perform any
|
|
operation except unsealing until it is sealed. Secrets cannot be accessed
|
|
in any way until the vault is unsealed. This command allows you to enter
|
|
a portion of the master key to unseal the vault.
|
|
|
|
The unseal key can be specified via the command line, but this is
|
|
not recommended. The key may then live in your terminal history. This
|
|
only exists to assist in scripting.

|
|
|
General Options:

` + generalOptionsUsage() + `
|
|
|
|
Unseal Options:
|
|
|
|
-reset Reset the unsealing process by throwing away
|
|
prior keys in process to unseal the vault.
