Because in some circumstances the crypto is skipped regardless of the
communication settings by the Mifare DESFire (e.g. when reading a file which is
writable with any key), do not abort if the crypto fail, and make it possible
to the user to catch such an event to fix his code accordingly.
Only display crypto diagnostic if compiled with debug support.
Please note that according to the NXP documentation of the Mifare DESFire EV1,
the mifare_desfire_authenticate_iso() function can be used using either 3DES or
3K3DES keys. The former has not been tested yet and is likely not to work. To
word it differently, this is a 3K3DES crypto support, not a ISO authentication
support...
The autohell hack sucks and should be fixed, but I was unable to find the magic
trick to prevent automake from building broken libtool rules which produce
warnings about portability :-/.
- Lookup for crypto functions in libcrypto instead of libssl. Some systems
(Mac OS) do not provide libssl, and the other have crypto functions in
libcrypto but libssl is dynamically linked against libcrypto:
% ldd /usr/lib/libssl.so
/usr/lib/libssl.so:
libcrypto.so.6 => /lib/libcrypto.so.6 (0x800c00000)
libc.so.7 => /lib/libc.so.7 (0x800647000)
- Do not explicitly link against libssl (instead of libcrypto BTW): the
autotools magic already does this at some point;
- Improve error message when headers cannot be found.
After trying to tweak gindent so that it does not mess-up my ASCII art, give
and read the help of Vim to setup 'cinoptions' according to my needs
(cino=t0(0). This changeset reindent some bits that where not indented as they
should. A future commit will reindent the switch/case according to my (bad)
taste now that I have setup cindent correctly on my system (cino=t0(0:0).
The code can work with virtually any size of DESFire (since the operating
system embedded in the card handle almost everything), so there is no need for
us to distinguish cards of different sizes.
