text: # Notes on the wolfssl-fips project
  
  First, if you did not get the FIPS files with your archive, you must contact
  wolfSSL to obtain them.
  
  
  # Building the wolfssl-fips project
  
  The wolfCrypt FIPS library for Windows is a part of the wolfSSL library. It
  must be built as a static library, for the moment.
  
  The library project is built with Whole Program Optimization disabled. This is
  required so that necessary components of the library are not optimized away.
  There are two functions added to the library that are used as markers in
  memory for the in-core memory check of the code. WPO consolidates them into a
  single function. WPO also optimizes away the automatic FIPS entry function.
  
  Each of the source files inside the FIPS boundary defines their own code and
  constant section. The code section names start with ".fipsA$" and the constant
  section names start with ".fipsB$". Each subsection has a letter to organize
  them in a secific order. This specific ordering puts marker functions and
  constants on either end of the boundary so it can be hashed.
  
  
  # In Core Memory Test
  
  The In Core Memory test calculates a checksum (HMAC-SHA256) of the wolfCrypt
  FIPS library code and constant data and compares it with a known value in
  the code.
  
  The Randomized Base Address setting needs to be disabled on the 32-bit builds
  but can be enabled on the 64-bit builds. In the 32-bit mode the addresses
  being different throws off the in-core memory calculation. It looks like in
  64-bit mode the library uses all offsets, so the core hash calculation
  is the same every time.
  
  The "verifyCore" check value in the source fips_test.c needs to be updated when
  building the code. The POS performs this check and the default failure callback
  will print out the calculated checksum. When developing your code, copy this
  value and paste it back into your code in the verifyCore initializer then
  rebuild the code. When statically linking, you may have to recalculate your
  check value when changing your application.
  
  
  # Build Options
  
  The default build options should be the proper default set of options:
  
   * HAVE_FIPS
   * HAVE_THREAD_LS
   * HAVE_AESGCM
   * HAVE_HASHDRBG
   * WOLFSSL_SHA384
   * WOLFSSL_SHA512
   * NO_HC128
   * NO_RC4
   * NO_RABBIT
   * NO_DSA
   * NO_MD4
  
  The "NO" options explicitly disable algorithms that are not allowed in
  FIPS mode.
  
  Additionally one may enable:
  
   * HAVE_ECC
   * OPENSSL_EXTRA
   * WOLFSSL_KEY_GEN
  
  These settings are defined in IDE/WIN/user_settings.h.
