This is a work in progress. + +# The one thing that must be configured here is which Hardware +# Adaption Layer ("HAL") to build into Cryptlib. Due to the need to +# support different Cryptech configurations on different boards, it's +# not really possible to provide a single HAL which supports all +# Cryptech configurations in a sane way, so you have to pick one. +# This makefile provides a default, but you can override it by +# providing a value for the CRYPTECH_HAL makefile variable on the +# command line, or by setting the CRYPTECH_HAL environment variable +# (explicit argument overrides environment variable, see GNU make +# documentation for details). + +ifndef CRYPTECH_HAL + CRYPTECH_HAL := src/cryptech_novena_i2c_simple.c +endif + +# Notes on the option settings we use when building cryptlib: +# +# - Python extension modules need to be position-independent code. We +# could handle this by building cryptlib as a shared library, but +# for the moment it's simpler to force even the static library to +# use position independent code. Works with gcc and clang, anyway, +# which are the only compilers we care about at the moment. +# +# - Point of the exercise is a hardware device, and we want the full +# set of SHA-2 digests. +# +# - See config.h for other options we might want to add here. In +# particular, USE_ECDH, USE_ECDSA, and USE_GCM all touch on subjects +# that came up during the early Cryptech design discussions. + +################################################################ + +# From here down is not intended to be user-servicable.
