+ WARNING
+ -------
+
+ This version of OpenSSL is built in a way that supports operation in
+ the so called FIPS mode. Note though that the library as we build it
+ is not FIPS 140-2 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:
+ * The FIPS validation support is significantly different from the
+ upstream FIPS support. For example the FIPS integrity verification
+ check is implemented differently as the FIPS module is built inside
+ the shared library. The HMAC-SHA256 checksums of the whole shared
+ libraries are verified. Also note that the FIPS integrity
+ verification check requires that the libcrypto and libssl shared
+ library files are unmodified which means that it will fail if these
+ files are changed for example by prelink.
+ * If the file /etc/system-fips is present the integrity verification
+ and selftests of the crypto algorithms are run inside the library
+ constructor code.
+ * With the /etc/system-fips present 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.
+ With the /etc/system-fips present 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.
+ * The library was patched so the certificates, CRLs and other objects
+ signed with use of MD5 fail verification as the MD5 is too insecure
+ to be used for signatures. If the environment variable
+ OPENSSL_ENABLE_MD5_VERIFY is set, the verification can proceed
+ normally.
+ * If the OPENSSL_ENFORCE_MODULUS_BITS environment variable is set,
+ the library will not allow generation of DSA and RSA keys with
+ other lengths than specified in the FIPS 186-4 standard.
