$ make -C <repository_root>/enclave
The default docker-install target will create a reproducible build environment image using
enclave/docker/Dockerfile, build the enclave inside a container based on the image, and
install the resulting enclave into service/kbupd/res/enclave/. The Dockerfile will
download a stock dated-snapshot debian Docker image. The Debian project builds their
docker images reproducibly, based on the a snapshot of the debian repos on the date of the
build from the Debian Snapshot Project. Make will then be
run inside the newly built Docker Debian image as in the Building with
Debian section below:
NB: the installed enclave will be signed with the SGX debug flag enabled by an
automatically generated signing key. Due to Intel SGX licensing requirements, a debug
enclave can currently only be run with SGX debugging enabled, allowing inspection of its
encrypted memory, and invalidating its security properties. To use an enclave in
production, provide the Intel-whitelisted signing key as
enclave/libkbupd_enclave.hardened.key before building. Alternatively, the generated
enclave/build/libkbupd_enclave.hardened.signdata file can be signed and saved as
enclave/build/libkbupd_enclave.sig with corresponding public key at
enclave/libkbupd_enclave.pub, and signed using make sign install.

$ make -C <repository_root>/enclave debuild install
debuild is a debian tool used to build debian packages after it sanitizes the
environment and installs build dependences. The primary advantage of using debian
packaging tools in this case is to leverage the Reproducible
Builds project. While building a debian
package, debuild will record the names and versions of all detected build dependencies
into a *.buildinfo file, for future reproducibility debugging.
The debuild target also builds parts needed from the Intel SGX SDK v2.7.1 after cloning it
from github.
The install target copies the enclave to service/kbupd/res/enclave/, which should
potentially be checked in to be used with the service.
The sign target may also be used as described in Building reproducibly with
Docker to produce a release-mode enclave.

The all target will probably fail to reproduce the same binary as above, but doesn't
require Docker or Debian Linux.
The sign target may also be used as described in Building reproducibly with
