+# 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_eim_trng.c
+endif
+
+# RNG hack defaults to enabled if we're building the TRNG, disabled
+# otherwise.  This is a kludge, do better later.
+
+ifndef CRYPTECH_RANDOM
+  CRYPTECH_RANDOM := $(and $(findstring trng,${CRYPTECH_HAL}),src/cryptech_random.c)

+
+# 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.
