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.
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.
"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order. Thusly fixed.
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.
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
consistent in the source tree and replaced `/bin/rm' by `rm'. Additonally
cleaned up the `make links' target: Remove unnecessary semicolons, subsequent
redundant removes, inline point.sh into mklink.sh to speed processing and no
longer clutter the display with confusing stuff. Instead only the actually
done links are displayed.
