This involves using HMAC-SHA256 with the unwrapped DEK as the key and a specific concatenation of metadata as data. The metadata consists of \"ResourceKeyDigest:\", the UTF-8 encoded `resource_name`, \":\", and the UTF-8 encoded `perimeter_id`. An example shows generating the hash using `openssl` with a sample `resource_name`, `perimeter_id`, and `unwrapped_dek`.\n"]]
