providers/build.info

   1 # We place all implementations in static libraries, and then let the
   2 # provider mains pilfer what they want through symbol resolution when
   3 # linking.
   4 #
   5 # The non-legacy implementations (libimplementations) must be made FIPS
   6 # agnostic as much as possible, as well as the common building blocks
   7 # (libcommon).  The legacy implementations (liblegacy) will never be
   8 # part of the FIPS provider.
   9 #
  10 # If there is anything that isn't FIPS agnostic, it should be set aside
  11 # in its own source file, which is then included directly into other
  12 # static libraries geared for FIPS and non-FIPS providers, and built
  13 # separately.
  14 #
  15 # libcommon.a           Contains common building blocks, potentially
  16 #                       needed both by non-legacy and legacy code.
  17 #
  18 # libimplementations.a  Contains all non-legacy implementations.
  19 # liblegacy.a           Contains all legacy implementaions.
  20 #
  21 # libfips.a             Contains all things needed to support
  22 #                       FIPS implementations, such as code from
  23 #                       crypto/ and object files that contain
  24 #                       FIPS-specific code.  FIPS_MODE is defined
  25 #                       for this library.  The FIPS module uses
  26 #                       this.
  27 # libnonfips.a          Corresponds to libfips.a, but built with
  28 #                       FIPS_MODE undefined.  The default and legacy
  29 #                       providers use this.
