Non FIPS algorithms are not normally allowed in FIPS mode.
Any attempt to use them via high level functions will return an error.
The low level non-FIPS algorithm functions cannot return errors so they
produce assertion failures. HMAC also has to give an assertion error because
it (erroneously) can't return an error either.
There are exceptions (such as MD5 in TLS and non cryptographic use of
algorithms) and applications can override the blocking and use non FIPS
algorithms anyway.
For low level functions the override is perfomed by prefixing the algorithm
initalization function with "private_" for example private_MD5_Init().
For high level functions an override is performed by setting a flag in
the context.
and make all files the depend on it include it without prefixing it
with openssl/.
This means that all Makefiles will have $(TOP) as one of the include
directories.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
objects) or OPENSSL_BUILD_SHLIBSSL (for files that end up as libssl
objects) is defined, redefine OPENSSL_EXTERN to be OPENSSL_EXPORT.
This is actually only important on Win32, and can safely be ignored in
all other cases, at least for now.
This was meant for building individual ciphers separately;
but nothing of this is maintained, it does not work
because we rely on central configuration by the Configure
utility with <openssl/opensslconf.h> etc., so the files
are only wasting space and time.
in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers. So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes. Argh.
There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.
instead I've picked "enc", because that's what's in the prototypes.
("_encrypt" is reserved only as an external name, but still
using it in an application doesn't look like good style to me --
and it certainly isn't if the point is just avoiding shadowing,
which is apparently why the previous name "encrypt" was changed.)
