Cubbyhole Secret Backend

Name: cubbyhole

The cubbyhole secret backend is used to store arbitrary secrets within the configured physical storage for Vault. It is mounted at the cubbyhole/ prefix by default and cannot be mounted elsewhere or removed.

This backend differs from the generic backend in that the generic backend's values are accessible to any token with read privileges on that path. In this backend, paths are scoped per token; no token can read secrets placed in another token's cubbyhole. When the token expires, its cubbyhole is destroyed.

Also unlike the generic backend, because the cubbyhole's lifetime is linked to an authentication token, there is no concept of a lease or lease TTL for values contained in the token's cubbyhole.

Writing to a key in the cubbyhole/ backend will replace the old value, the sub-fields are not merged together.

Quick Start

The cubbyhole backend allows for writing keys with arbitrary values.

As an example, we can write a new key "foo" to the cubbyhole backend, which is mounted at cubbyhole/:

$ vault write cubbyhole/foo \
    zip=zap
Success! Data written to: cubbyhole/foo

This writes the key with the "zip" field set to "zap". We can test this by doing a read:

$ vault read cubbyhole/foo
Key           	Value
zip           	zap

As expected, the value previously set is returned to us.
