+# Cryptech project makefile for Cryptlib. 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.
