 ## dmverity Layer Hashing
 
-To ensure the container that is being deployed is the intended container, the `confcom` tooling uses [dmverity hashing](https://www.kernel.org/doc/html/latest/admin-guide/device-mapper/verity.html). This is done by downloading the container locally with the Docker Daemon (or using a pre-downloaded tar file of the OCI image) and performing the dmverity hashing using the [dmverity-vhd tool](https://github.com/microsoft/hcsshim/tree/main/cmd/dmverity-vhd). These layer hashes are placed into the Rego security policy in the "layers" field of their respective container. Note that these dmverity layer hashes are different than the layer hashes reported by `docker image inspect`.
