addresses: CWE-459

Fail-safe procedures can explicitly require cleanup of temporary state, resources, or privileges on failure to avoid leaving the system in an inconsistent state.

addresses: CWE-459

The explicit delete step when information is no longer needed implements the cleanup that this weakness omits.
