• key_info: a map indexed by the versions found in the keys list containing the following subkeys:
  • build_date: the time (in UTC) at which the Vault binary used to run the Vault server was built. Note: Only tracked from version 1.11.0 or greater
  • previous_version: the version installed prior to this version or null if no prior version exists
  • timestamp_installed: the time (in UTC) at which the version was installed
