Note though that the library as we build it + is not FIPS validated and the FIPS mode is present for testing purposes + only. + + This version also contains a few differences from the upstream code + some of which are: + * There are added changes forward ported from the upstream OpenSSL + 0.9.8 FIPS branch however the FIPS integrity verification check + is implemented differently from the upstream FIPS validated OpenSSL + module. It verifies HMAC-SHA256 checksum of the whole shared + libraries. For this reason the changes are ported to files in the + crypto directory and not in a separate fips subdirectory. Also + note that the FIPS integrity verification check requires unmodified + libcrypto and libssl shared library files which means that it will + fail if these files are modified for example by prelink. + * The module respects the kernel FIPS flag /proc/sys/crypto/fips and + tries to initialize the FIPS mode if it is set to 1 aborting if the + FIPS mode could not be initialized. It is also possible to force the + OpenSSL library to FIPS mode especially for debugging purposes by + setting the environment variable OPENSSL_FORCE_FIPS_MODE. + * If the environment variable OPENSSL_NO_DEFAULT_ZLIB is set the module + will not automatically load the built in compression method ZLIB + when initialized. Applications can still explicitely ask for ZLIB + compression method. + DESCRIPTION -----------
