»KV Secrets Engine - Version 1
kv secrets engine is used to store arbitrary secrets within the
configured physical storage for Vault.
Writing to a key in the
kv backend will replace the old value; sub-fields are
not merged together.
Key names must always be strings. If you write non-string values directly via the CLI, they will be converted into strings. However, you can preserve non-string values by writing the key/value pairs to Vault from a JSON file or using the HTTP API.
This secrets engine honors the distinction between the
capabilities inside ACL policies.
Note: Path and key names are not obfuscated or encrypted; only the values set on keys are. You should not store sensitive information as part of a secret's path.
To enable a version 1 kv store:
vault secrets enable -version=1 kv
After the secrets engine is configured and a user/machine has a Vault token with
the proper permission, it can generate credentials. The
kv secrets engine
allows for writing keys with arbitrary values.
Write arbitrary data:
$ vault kv put kv/my-secret my-value=s3cr3tSuccess! Data written to: kv/my-secret
Read arbitrary data:
$ vault kv get kv/my-secretKey Value--- -----my-value s3cr3t
List the keys:
$ vault kv list kv/Keys----my-secret
Delete a key:
$ vault kv delete kv/my-secretSuccess! Data deleted (if it existed) at: kv/my-secret
Unlike other secrets engines, the KV secrets engine does not enforce TTLs
for expiration. Instead, the
lease_duration is a hint for how often consumers
should check back for a new value.
If provided a key of
ttl, the KV secrets engine will utilize this value
as the lease duration:
$ vault kv put kv/my-secret ttl=30m my-value=s3cr3tSuccess! Data written to: kv/my-secret
Even with a
ttl set, the secrets engine never removes data on its own. The
ttl key is merely advisory.
When reading a value with a
ttl, both the
ttl key and the refresh interval
will reflect the value:
$ vault kv get kv/my-secretKey Value--- -----my-value s3cr3tttl 30m

The KV secrets engine has a full HTTP API. Please see the KV secrets engine API for more details.
