# libcommon.a           Contains common building blocks and other routines,
#                       potentially needed by any of our providers.
#
# libfips.a             Contains all algorithm implementations that should
#                       go in the FIPS provider.  The compilations for this
#                       library are all done with FIPS_MODULE defined.
#
# liblegacy.a           Contains all algorithm implementations that should
#                       go into the legacy provider.  The compilations for
#                       this library are all done with STATIC_LEGACY defined.
#
# libdefault.a          Contains all algorithm implementations that should
#                       into the default or base provider.
#
# To be noted is that the FIPS provider shares source code with libcrypto,
# which means that select source files from crypto/ are compiled for
# libfips.a the sources from providers/implementations.
#
# This is how a provider module should be linked:
#
#     -o {modulename}.so {object files...} lib{modulename}.a libcommon.a
#
# It is crucial that code that checks the FIPS_MODULE macro ends up in
# libfips.a.
# It is crucial that code that checks the STATIC_LEGACY macro ends up in
# liblegacy.a.
# It is recommended that code that is written for libcommon.a doesn't end
# up depending on libfips.a, liblegacy.a or libdefault.a
#
# Code in providers/implementations/ should be written in such a way that
# the OSSL_DISPATCH arrays (and preferably the majority of the actual code)
# end up in either libfips.a, liblegacy.a or libdefault.a.
